  <pre>Creates a task and adds it to a queue. Tasks cannot be updated after creation; there is no UpdateTask command. * The maximum task size is 100KB.

Args:
  parent: string, Required. The queue name. For example: `projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID` The queue must already exist. (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for CreateTask.
  &quot;responseView&quot;: &quot;A String&quot;, # The response_view specifies which subset of the Task will be returned. By default response_view is BASIC; not all information is retrieved by default because some data, such as payloads, might be desirable to return only when needed because of its large size or because of the sensitivity of data that it contains. Authorization for FULL requires `cloudtasks.tasks.fullView` [Google IAM](https://cloud.google.com/iam/) permission on the Task resource.
  &quot;task&quot;: { # A unit of scheduled work. # Required. The task to add. Task names have the following format: `projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks/TASK_ID`. The user can optionally specify a task name. If a name is not specified then the system will generate a random unique task id, which will be set in the task returned in the response. If schedule_time is not set or is in the past then Cloud Tasks will set it to the current time. Task De-duplication: Explicitly specifying a task ID enables task de-duplication. If a task&#x27;s ID is identical to that of an existing task or a task that was deleted or executed recently then the call will fail with ALREADY_EXISTS. If the task&#x27;s queue was created using Cloud Tasks, then another task with the same name can&#x27;t be created for ~1hour after the original task was deleted or executed. If the task&#x27;s queue was created using queue.yaml or queue.xml, then another task with the same name can&#x27;t be created for ~9days after the original task was deleted or executed. Because there is an extra lookup cost to identify duplicate task names, these CreateTask calls have significantly increased latency. Using hashed strings for the task id or for the prefix of the task id is recommended. Choosing task ids that are sequential or have sequential prefixes, for example using a timestamp, causes an increase in latency and error rates in all task commands. The infrastructure relies on an approximately uniform distribution of task ids to store and serve tasks efficiently.
    &quot;appEngineHttpRequest&quot;: { # App Engine HTTP request. The message defines the HTTP request that is sent to an App Engine app when the task is dispatched. Using AppEngineHttpRequest requires [`appengine.applications.get`](https://cloud.google.com/appengine/docs/admin-api/access-control) Google IAM permission for the project and the following scope: `https://www.googleapis.com/auth/cloud-platform` The task will be delivered to the App Engine app which belongs to the same project as the queue. For more information, see [How Requests are Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed) and how routing is affected by [dispatch files](https://cloud.google.com/appengine/docs/python/config/dispatchref). Traffic is encrypted during transport and never leaves Google datacenters. Because this traffic is carried over a communication mechanism internal to Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS). The request to the handler, however, will appear to have used the HTTP protocol. The AppEngineRouting used to construct the URL that the task is delivered to can be set at the queue-level or task-level: * If set, app_engine_routing_override is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing. The `url` that the task will be sent to is: * `url =` host `+` relative_uri Tasks can be dispatched to secure app handlers, unsecure app handlers, and URIs restricted with [`login: admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref). Because tasks are not run as any user, they cannot be dispatched to URIs restricted with [`login: required`](https://cloud.google.com/appengine/docs/standard/python/config/appref) Task dispatches also do not follow redirects. The task attempt has succeeded if the app&#x27;s request handler returns an HTTP response code in the range [`200` - `299`]. The task attempt has failed if the app&#x27;s handler returns a non-2xx response code or Cloud Tasks does not receive response before the deadline. Failed tasks will be retried according to the retry configuration. `503` (Service Unavailable) is considered an App Engine system error instead of an application error and will cause Cloud Tasks&#x27; traffic congestion control to temporarily throttle the queue&#x27;s dispatches. Unlike other types of task targets, a `429` (Too Many Requests) response from an app handler does not cause traffic congestion control to throttle the queue. # HTTP request that is sent to the App Engine app handler. An App Engine task is a task that has AppEngineHttpRequest set.
      &quot;appEngineRouting&quot;: { # App Engine Routing. Defines routing characteristics specific to App Engine - service, version, and instance. For more information about services, versions, and instances see [An Overview of App Engine](https://cloud.google.com/appengine/docs/python/an-overview-of-app-engine), [Microservices Architecture on Google App Engine](https://cloud.google.com/appengine/docs/python/microservices-on-app-engine), [App Engine Standard request routing](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed), and [App Engine Flex request routing](https://cloud.google.com/appengine/docs/flexible/python/how-requests-are-routed). # Task-level setting for App Engine routing. If set, app_engine_routing_override is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing.
        &quot;host&quot;: &quot;A String&quot;, # Output only. The host that the task is sent to. The host is constructed from the domain name of the app associated with the queue&#x27;s project ID (for example .appspot.com), and the service, version, and instance. Tasks which were created using the App Engine SDK might have a custom domain name. For more information, see [How Requests are Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed).
        &quot;instance&quot;: &quot;A String&quot;, # App instance. By default, the task is sent to an instance which is available when the task is attempted. Requests can only be sent to a specific instance if [manual scaling is used in App Engine Standard](https://cloud.google.com/appengine/docs/python/an-overview-of-app-engine?hl=en_US#scaling_types_and_instance_classes). App Engine Flex does not support instances. For more information, see [App Engine Standard request routing](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed) and [App Engine Flex request routing](https://cloud.google.com/appengine/docs/flexible/python/how-requests-are-routed).
        &quot;service&quot;: &quot;A String&quot;, # App service. By default, the task is sent to the service which is the default service when the task is attempted. For some queues or tasks which were created using the App Engine Task Queue API, host is not parsable into service, version, and instance. For example, some tasks which were created using the App Engine SDK use a custom domain name; custom domains are not parsed by Cloud Tasks. If host is not parsable, then service, version, and instance are the empty string.
        &quot;version&quot;: &quot;A String&quot;, # App version. By default, the task is sent to the version which is the default version when the task is attempted. For some queues or tasks which were created using the App Engine Task Queue API, host is not parsable into service, version, and instance. For example, some tasks which were created using the App Engine SDK use a custom domain name; custom domains are not parsed by Cloud Tasks. If host is not parsable, then service, version, and instance are the empty string.
      },
      &quot;body&quot;: &quot;A String&quot;, # HTTP request body. A request body is allowed only if the HTTP method is POST or PUT. It is an error to set a body on a task with an incompatible HttpMethod.
      &quot;headers&quot;: { # HTTP request headers. This map contains the header field names and values. Headers can be set when the task is created. Repeated headers are not supported but a header value can contain commas. Cloud Tasks sets some headers to default values: * `User-Agent`: By default, this header is `&quot;AppEngine-Google; (+http://code.google.com/appengine)&quot;`. This header can be modified, but Cloud Tasks will append `&quot;AppEngine-Google; (+http://code.google.com/appengine)&quot;` to the modified `User-Agent`. If the task has a body, Cloud Tasks sets the following headers: * `Content-Type`: By default, the `Content-Type` header is set to `&quot;application/octet-stream&quot;`. The default can be overridden by explicitly setting `Content-Type` to a particular media type when the task is created. For example, `Content-Type` can be set to `&quot;application/json&quot;`. * `Content-Length`: This is computed by Cloud Tasks. This value is output only. It cannot be changed. The headers below cannot be set or overridden: * `Host` * `X-Google-*` * `X-AppEngine-*` In addition, Cloud Tasks sets some headers when the task is dispatched, such as headers containing information about the task; see [request headers](https://cloud.google.com/tasks/docs/creating-appengine-handlers#reading_request_headers). These headers are set only when the task is dispatched, so they are not visible when the task is returned in a Cloud Tasks response. Although there is no specific limit for the maximum number of headers or the size, there is a limit on the maximum size of the Task. For more information, see the CreateTask documentation.
        &quot;a_key&quot;: &quot;A String&quot;,
      },
      &quot;httpMethod&quot;: &quot;A String&quot;, # The HTTP method to use for the request. The default is POST. The app&#x27;s request handler for the task&#x27;s target URL must be able to handle HTTP requests with this http_method, otherwise the task attempt fails with error code 405 (Method Not Allowed). See [Writing a push task request handler](https://cloud.google.com/appengine/docs/java/taskqueue/push/creating-handlers#writing_a_push_task_request_handler) and the App Engine documentation for your runtime on [How Requests are Handled](https://cloud.google.com/appengine/docs/standard/python3/how-requests-are-handled).
      &quot;relativeUri&quot;: &quot;A String&quot;, # The relative URI. The relative URI must begin with &quot;/&quot; and must be a valid HTTP relative URI. It can contain a path and query string arguments. If the relative URI is empty, then the root path &quot;/&quot; will be used. No spaces are allowed, and the maximum length allowed is 2083 characters.
    },
    &quot;createTime&quot;: &quot;A String&quot;, # Output only. The time that the task was created. `create_time` will be truncated to the nearest second.
    &quot;dispatchCount&quot;: 42, # Output only. The number of attempts dispatched. This count includes attempts which have been dispatched but haven&#x27;t received a response.
    &quot;dispatchDeadline&quot;: &quot;A String&quot;, # The deadline for requests sent to the worker. If the worker does not respond by this deadline then the request is cancelled and the attempt is marked as a `DEADLINE_EXCEEDED` failure. Cloud Tasks will retry the task according to the RetryConfig. Note that when the request is cancelled, Cloud Tasks will stop listening for the response, but whether the worker stops processing depends on the worker. For example, if the worker is stuck, it may not react to cancelled requests. The default and maximum values depend on the type of request: * For HTTP tasks, the default is 10 minutes. The deadline must be in the interval [15 seconds, 30 minutes]. * For App Engine tasks, 0 indicates that the request has the default deadline. The default deadline depends on the [scaling type](https://cloud.google.com/appengine/docs/standard/go/how-instances-are-managed#instance_scaling) of the service: 10 minutes for standard apps with automatic scaling, 24 hours for standard apps with manual and basic scaling, and 60 minutes for flex apps. If the request deadline is set, it must be in the interval [15 seconds, 24 hours 15 seconds]. Regardless of the task&#x27;s `dispatch_deadline`, the app handler will not run for longer than than the service&#x27;s timeout. We recommend setting the `dispatch_deadline` to at most a few seconds more than the app handler&#x27;s timeout. For more information see [Timeouts](https://cloud.google.com/tasks/docs/creating-appengine-handlers#timeouts). `dispatch_deadline` will be truncated to the nearest millisecond. The deadline is an approximate deadline.

If the worker or the redirected worker acknowledges the task by returning a successful HTTP response code ([`200` - `299`]), the task will be removed from the queue. If any other HTTP response code is returned or no response is received, the task will be retried according to the following: * User-specified throttling: retry configuration, rate limits, and the queue&#x27;s state. * System throttling: To prevent the worker from overloading, Cloud Tasks may temporarily reduce the queue&#x27;s effective rate. User-specified settings will not be changed. System throttling happens because: * Cloud Tasks backs off on all errors. Normally the backoff specified in rate limits will be used. But if the worker returns `429` (Too Many Requests), `503` (Service Unavailable), or the rate of errors is high, Cloud Tasks will use a higher backoff rate. The retry specified in the `Retry-After` HTTP response header is considered. * To prevent traffic spikes and to smooth sudden increases in traffic, dispatches ramp up slowly when the queue is newly created or idle and if large numbers of tasks suddenly become available to dispatch (due to spikes in create task rates, the queue being unpaused, or many tasks that are scheduled at the same time). # HTTP request that is sent to the task&#x27;s target.

Because this traffic is carried over a communication mechanism internal to Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS). The request to the handler, however, will appear to have used the HTTP protocol. The AppEngineRouting used to construct the URL that the task is delivered to can be set at the queue-level or task-level: * If set, app_engine_routing_override is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing. The `url` that the task will be sent to is: * `url =` host `+` relative_uri Tasks can be dispatched to secure app handlers, unsecure app handlers, and URIs restricted with [`login: admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref). Because tasks are not run as any user, they cannot be dispatched to URIs restricted with [`login: required`](https://cloud.google.com/appengine/docs/standard/python/config/appref) Task dispatches also do not follow redirects. The task attempt has succeeded if the app&#x27;s request handler returns an HTTP response code in the range [`200` - `299`]. The task attempt has failed if the app&#x27;s handler returns a non-2xx response code or Cloud Tasks does not receive response before the deadline. Failed tasks will be retried according to the retry configuration. `503` (Service Unavailable) is considered an App Engine system error instead of an application error and will cause Cloud Tasks&#x27; traffic congestion control to temporarily throttle the queue&#x27;s dispatches. Unlike other types of task targets, a `429` (Too Many Requests) response from an app handler does not cause traffic congestion control to throttle the queue. # HTTP request that is sent to the App Engine app handler.

If the task has a body, Cloud Tasks sets the following headers: * `Content-Type`: By default, the `Content-Type` header is set to `&quot;application/octet-stream&quot;`.

Note that when the request is cancelled, Cloud Tasks will stop listening for the response, but whether the worker stops processing depends on the worker. For example, if the worker is stuck, it may not react to cancelled requests. The default and maximum values depend on the type of request: * For HTTP tasks, the default is 10 minutes. The deadline must be in the interval [15 seconds, 30 minutes]. * For App Engine tasks, 0 indicates that the request has the default deadline. The default deadline depends on the [scaling type](https://cloud.google.com/appengine/docs/standard/go/how-instances-are-managed#instance_scaling) of the service: 10 minutes for standard apps with automatic scaling, 24 hours for standard apps with manual and basic scaling, and 60 minutes for flex apps. If the request deadline is set, it must be in the interval [15 seconds, 24 hours 15 seconds]. Regardless of the task&#x27;s `dispatch_deadline`, the app handler will not run for longer than than the service&#x27;s timeout. We recommend setting the `dispatch_deadline` to at most a few seconds more than the app handler&#x27;s timeout.

<div class="method">
    <code class="details" id="list">list(parent, pageSize=None, pageToken=None, responseView=None, x__xgafv=None)</code>
  <pre>Lists the tasks in a queue. By default, only the BASIC view is retrieved due to performance considerations; response_view controls the subset of information which is returned. The tasks may be returned in any order. The ordering may change at any time.

Args:
  parent: string, Required. The queue name. For example: `projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID` (required)
  pageSize: integer, Maximum page size. Fewer tasks than requested might be returned, even if more tasks exist; use next_page_token in the response to determine if more tasks exist. The maximum page size is 1000. If unspecified, the page size will be the maximum.
  pageToken: string, A token identifying the page of results to return. To request the first page results, page_token must be empty. To request the next page of results, page_token must be the value of next_page_token returned from the previous call to ListTasks method. The page token is valid for only 2 hours.
  responseView: string, The response_view specifies which subset of the Task will be returned. By default response_view is BASIC; not all information is retrieved by default because some data, such as payloads, might be desirable to return only when needed because of its large size or because of the sensitivity of data that it contains. Authorization for FULL requires `cloudtasks.tasks.fullView` [Google IAM](https://cloud.google.com/iam/) permission on the Task resource.
    Allowed values
      VIEW_UNSPECIFIED - Unspecified. Defaults to BASIC.
      BASIC - The basic view omits fields which can be large or can contain sensitive data. This view does not include the body in AppEngineHttpRequest. Bodies are desirable to return only when needed, because they can be large and because of the sensitivity of the data that you choose to store in it.
      FULL - All information is returned. Authorization for FULL requires `cloudtasks.tasks.fullView` [Google IAM](https://cloud.google.com/iam/) permission on the Queue resource.
  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

    { # Response message for listing tasks using ListTasks.
  &quot;nextPageToken&quot;: &quot;A String&quot;, # A token to retrieve next page of results. To return the next page of results, call ListTasks with this value as the page_token. If the next_page_token is empty, there are no more results.
  &quot;tasks&quot;: [ # The list of tasks.
    { # A unit of scheduled work.
      &quot;appEngineHttpRequest&quot;: { # App Engine HTTP request. The message defines the HTTP request that is sent to an App Engine app when the task is dispatched. Using AppEngineHttpRequest requires [`appengine.applications.get`](https://cloud.google.com/appengine/docs/admin-api/access-control) Google IAM permission for the project and the following scope: `https://www.googleapis.com/auth/cloud-platform` The task will be delivered to the App Engine app which belongs to the same project as the queue. For more information, see [How Requests are Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed) and how routing is affected by [dispatch files](https://cloud.google.com/appengine/docs/python/config/dispatchref). Traffic is encrypted during transport and never leaves Google datacenters. Because this traffic is carried over a communication mechanism internal to Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS). The request to the handler, however, will appear to have used the HTTP protocol. The AppEngineRouting used to construct the URL that the task is delivered to can be set at the queue-level or task-level: * If set, app_engine_routing_override is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing. The `url` that the task will be sent to is: * `url =` host `+` relative_uri Tasks can be dispatched to secure app handlers, unsecure app handlers, and URIs restricted with [`login: admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref). Because tasks are not run as any user, they cannot be dispatched to URIs restricted with [`login: required`](https://cloud.google.com/appengine/docs/standard/python/config/appref) Task dispatches also do not follow redirects. The task attempt has succeeded if the app&#x27;s request handler returns an HTTP response code in the range [`200` - `299`]. The task attempt has failed if the app&#x27;s handler returns a non-2xx response code or Cloud Tasks does not receive response before the deadline. Failed tasks will be retried according to the retry configuration. `503` (Service Unavailable) is considered an App Engine system error instead of an application error and will cause Cloud Tasks&#x27; traffic congestion control to temporarily throttle the queue&#x27;s dispatches. Unlike other types of task targets, a `429` (Too Many Requests) response from an app handler does not cause traffic congestion control to throttle the queue. # HTTP request that is sent to the App Engine app handler.

<div class="method">
    <code class="details" id="list_next">list_next(previous_request, previous_response)</code>
  <pre>Retrieves the next page of results.

Args:
  previous_request: The request for the previous page. (required)
  previous_response: The response from the request for the previous page. (required)

Returns:
  A request object that you can call &#x27;execute()&#x27; on to request the next
  page. Returns None if there are no more items in the collection.
    </pre>
</div>

<div class="method">
    <code class="details" id="run">run(name, body=None, x__xgafv=None)</code>
  <pre>Forces a task to run now. When this method is called, Cloud Tasks will dispatch the task, even if the task is already running, the queue has reached its RateLimits or is PAUSED. This command is meant to be used for manual debugging. For example, RunTask can be used to retry a failed task after a fix has been made or to manually force a task to be dispatched now. The dispatched task is returned. That is, the task that is returned contains the status after the task is dispatched but before the task is received by its target. If Cloud Tasks receives a successful response from the task&#x27;s target, then the task will be deleted; otherwise the task&#x27;s schedule_time will be reset to the time that RunTask was called plus the retry delay specified in the queue&#x27;s RetryConfig. RunTask returns NOT_FOUND when it is called on a task that has already succeeded or permanently failed.

Args:
  name: string, Required. The task name. For example: `projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks/TASK_ID` (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for forcing a task to run now using RunTask.
  &quot;responseView&quot;: &quot;A String&quot;, # The response_view specifies which subset of the Task will be returned. By default response_view is BASIC; not all information is retrieved by default because some data, such as payloads, might be desirable to return only when needed because of its large size or because of the sensitivity of data that it contains. Authorization for FULL requires `cloudtasks.tasks.fullView` [Google IAM](https://cloud.google.com/iam/) permission on the Task resource.
}

  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

    { # A unit of scheduled work.
  &quot;appEngineHttpRequest&quot;: { # App Engine HTTP request. The message defines the HTTP request that is sent to an App Engine app when the task is dispatched. Using AppEngineHttpRequest requires [`appengine.applications.get`](https://cloud.google.com/appengine/docs/admin-api/access-control) Google IAM permission for the project and the following scope: `https://www.googleapis.com/auth/cloud-platform` The task will be delivered to the App Engine app which belongs to the same project as the queue. For more information, see [How Requests are Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed) and how routing is affected by [dispatch files](https://cloud.google.com/appengine/docs/python/config/dispatchref). Traffic is encrypted during transport and never leaves Google datacenters. Because this traffic is carried over a communication mechanism internal to Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS). The request to the handler, however, will appear to have used the HTTP protocol. The AppEngineRouting used to construct the URL that the task is delivered to can be set at the queue-level or task-level: * If set, app_engine_routing_override is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing. The `url` that the task will be sent to is: * `url =` host `+` relative_uri Tasks can be dispatched to secure app handlers, unsecure app handlers, and URIs restricted with [`login: admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref). Because tasks are not run as any user, they cannot be dispatched to URIs restricted with [`login: required`](https://cloud.google.com/appengine/docs/standard/python/config/appref) Task dispatches also do not follow redirects. The task attempt has succeeded if the app&#x27;s request handler returns an HTTP response code in the range [`200` - `299`]. The task attempt has failed if the app&#x27;s handler returns a non-2xx response code or Cloud Tasks does not receive response before the deadline. Failed tasks will be retried according to the retry configuration. `503` (Service Unavailable) is considered an App Engine system error instead of an application error and will cause Cloud Tasks&#x27; traffic congestion control to temporarily throttle the queue&#x27;s dispatches. Unlike other types of task targets, a `429` (Too Many Requests) response from an app handler does not cause traffic congestion control to throttle the queue. # HTTP request that is sent to the App Engine app handler. An App Engine task is a task that has AppEngineHttpRequest set.
    &quot;appEngineRouting&quot;: { # App Engine Routing. Defines routing characteristics specific to App Engine - service, version, and instance.

This header can be modified, but Cloud Tasks will append `&quot;AppEngine-Google; (+http://code.google.com/appengine)&quot;` to the modified `User-Agent`. If the task has a body, Cloud Tasks sets the following headers: * `Content-Type`: By default, the `Content-Type` header is set to `&quot;application/octet-stream&quot;`. The default can be overridden by explicitly setting `Content-Type` to a particular media type when the task is created. For example, `Content-Type` can be set to `&quot;application/json&quot;`. * `Content-Length`: This is computed by Cloud Tasks. This value is output only. It cannot be changed. The headers below cannot be set or overridden: * `Host` * `X-Google-*` * `X-AppEngine-*` In addition, Cloud Tasks sets some headers when the task is dispatched, such as headers containing information about the task; see [request headers](https://cloud.google.com/tasks/docs/creating-appengine-handlers#reading_request_headers). These headers are set only when the task is dispatched, so they are not visible when the task is returned in a Cloud Tasks response. Although there is no specific limit for the maximum number of headers or the size, there is a limit on the maximum size of the Task. For more information, see the CreateTask documentation.

Note that when the request is cancelled, Cloud Tasks will stop listening for the response, but whether the worker stops processing depends on the worker. For example, if the worker is stuck, it may not react to cancelled requests. The default and maximum values depend on the type of request: * For HTTP tasks, the default is 10 minutes. The deadline must be in the interval [15 seconds, 30 minutes]. * For App Engine tasks, 0 indicates that the request has the default deadline. The default deadline depends on the [scaling type](https://cloud.google.com/appengine/docs/standard/go/how-instances-are-managed#instance_scaling) of the service: 10 minutes for standard apps with automatic scaling, 24 hours for standard apps with manual and basic scaling, and 60 minutes for flex apps. If the request deadline is set, it must be in the interval [15 seconds, 24 hours 15 seconds]. Regardless of the task&#x27;s `dispatch_deadline`, the app handler will not run for longer than than the service&#x27;s timeout. We recommend setting the `dispatch_deadline` to at most a few seconds more than the app handler&#x27;s timeout.
