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 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 and how routing is affected by
dispatch files. 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 app_engine_routing_override is set on the queue, this value 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. Because tasks are not run as any user, they cannot be dispatched to URIs restricted with
login: required Task dispatches also do not follow redirects. The task attempt has succeeded if the app’s request handler returns an HTTP response code in the range [
200 -
299]. The task attempt has failed if the app’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’ traffic congestion control to temporarily throttle the queue’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.

Associates members, or principals, with a role.
Request message for BufferTask.
Response message for BufferTask.

Describes the customer-managed encryption key (CMEK) configuration associated with a project and location.
Request message for CreateTask.
A generic empty message that you can re-use to avoid defining duplicated empty messages in your APIs. A typical example is to use it as the request or the response type of an API method. For instance: service Foo { rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty); }
Represents a textual expression in the Common Expression Language (CEL) syntax. CEL is a C-like expression language. The syntax and semantics of CEL are documented at https://github.com/google/cel-spec. Example (Comparison): title: “Summary size limit” description: “Determines if a summary is less than 100 chars” expression: “document.summary.size() < 100” Example (Equality): title: “Requestor is owner” description: “Determines if requestor is the document owner” expression: “document.owner == request.auth.claims.email” Example (Logic): title: “Public documents” description: “Determine whether the document should be publicly visible” expression: “document.type != ‘private’ && document.type != ‘internal’” Example (Data Manipulation): title: “Notification string” description: “Create a notification string with a timestamp.” expression: “’New message received at ’ + string(document.create_time)” The exact variables and functions that may be referenced within an expression are determined by the service that evaluates it. See the service documentation for additional information.
Request message for GetIamPolicy method.
Encapsulates settings provided to GetIamPolicy.
Defines a header message. A header can have a key and a value.
Wraps the Header object.
Message that represents an arbitrary HTTP body. It should only be used for payload formats that can’t be represented as JSON, such as raw binary or an HTML page. This message can be used both in streaming and non-streaming API methods in the request as well as the response. It can be used as a top-level request field, which is convenient if one wants to extract parameters from either the URL or HTTP template into the request fields and also want access to the raw HTTP body. Example: message GetResourceRequest { // A unique request id. string request_id = 1; // The raw HTTP body is bound to this field. google.api.HttpBody http_body = 2; } service ResourceService { rpc GetResource(GetResourceRequest) returns (google.api.HttpBody); rpc UpdateResource(google.api.HttpBody) returns (google.protobuf.Empty); } Example with streaming methods: service CaldavService { rpc GetCalendar(stream google.api.HttpBody) returns (stream google.api.HttpBody); rpc UpdateCalendar(stream google.api.HttpBody) returns (stream google.api.HttpBody); } Use of this type only changes how the request and response bodies are handled, all other features will continue to work unchanged.
HTTP request. The task will be pushed to the worker as an HTTP request. 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’s state. * System throttling: To prevent the worker from overloading, Cloud Tasks may temporarily reduce the queue’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 target. When specified as a Queue, all the tasks with
HttpRequest will be overridden according to the target.

A resource that represents a Google Cloud location.
Contains information needed for generating an
OAuth token. This type of authorization should generally only be used when calling Google APIs hosted on *.googleapis.com.
Contains information needed for generating an
OpenID Connect token. This type of authorization can be used for many scenarios, including calling Cloud Run, or endpoints where you intend to validate the token yourself.
PathOverride. Path message defines path override for HTTP targets.
Request message for PauseQueue.
An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources. A
Policy is a collection of
bindings. A
binding binds one or more
members, or principals, to a single
role. Principals can be user accounts, service accounts, Google groups, and domains (such as G Suite). A
role is a named list of permissions; each
role can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a
binding can also specify a
condition, which is a logical expression that allows access to a resource only if the expression evaluates to
true. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the
IAM documentation.
JSON example: { "bindings": [ { "role": "roles/resourcemanager.organizationAdmin", "members": [ "user:mike@example.com", "group:admins@example.com", "domain:google.com", "serviceAccount:my-project-id@appspot.gserviceaccount.com" ] }, { "role": "roles/resourcemanager.organizationViewer", "members": [ "user:eve@example.com" ], "condition": { "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression": "request.time < timestamp('2020-10-01T00:00:00.000Z')", } } ], "etag": "BwWWja0YfJA=", "version": 3 } YAML example: bindings: - members: - user:mike@example.com - group:admins@example.com - domain:google.com - serviceAccount:my-project-id@appspot.gserviceaccount.com role: roles/resourcemanager.organizationAdmin - members: - user:eve@example.com role: roles/resourcemanager.organizationViewer condition: title: expirable access description: Does not grant access after Sep 2020 expression: request.time < timestamp('2020-10-01T00:00:00.000Z') etag: BwWWja0YfJA= version: 3 For a description of IAM and its features, see the
IAM documentation.
Gets information about a location.
Gets the CMEK config. Gets the Customer Managed Encryption Key configured with the Cloud Tasks lcoation. By default there is no kms_key configured.
Lists information about the supported locations for this service.
Creates a queue. Queues created with this method allow tasks to live for a maximum of 31 days. After a task is 31 days old, the task will be deleted regardless of whether it was dispatched or not. WARNING: Using this method may have unintended side effects if you are using an App Engine
queue.yaml or
queue.xml file to manage your queues. Read
Overview of Queue Management and queue.yaml before using this method.
Deletes a queue. This command will delete the queue even if it has tasks in it. Note: If you delete a queue, you may be prevented from creating a new queue with the same name as the deleted queue for a tombstone window of up to 3 days. During this window, the CreateQueue operation may appear to recreate the queue, but this can be misleading. If you attempt to create a queue with the same name as one that is in the tombstone window, run GetQueue to confirm that the queue creation was successful. If GetQueue returns 200 response code, your queue was successfully created with the name of the previously deleted queue. Otherwise, your queue did not successfully recreate. WARNING: Using this method may have unintended side effects if you are using an App Engine
queue.yaml or
queue.xml file to manage your queues. Read
Overview of Queue Management and queue.yaml before using this method.
Gets a queue.
Gets the access control policy for a Queue. Returns an empty policy if the resource exists and does not have a policy set. Authorization requires the following
Google IAM permission on the specified resource parent: *
cloudtasks.queues.getIamPolicyLists queues. Queues are returned in lexicographical order.
Updates a queue. This method creates the queue if it does not exist and updates the queue if it does exist. Queues created with this method allow tasks to live for a maximum of 31 days. After a task is 31 days old, the task will be deleted regardless of whether it was dispatched or not. WARNING: Using this method may have unintended side effects if you are using an App Engine
queue.yaml or
queue.xml file to manage your queues. Read
Overview of Queue Management and queue.yaml before using this method.
Pauses the queue. If a queue is paused then the system will stop dispatching tasks until the queue is resumed via ResumeQueue. Tasks can still be added when the queue is paused. A queue is paused if its state is PAUSED.
Purges a queue by deleting all of its tasks. All tasks created before this method is called are permanently deleted. Purge operations can take up to one minute to take effect. Tasks might be dispatched before the purge takes effect. A purge is irreversible.
Resume a queue. This method resumes a queue after it has been PAUSED or DISABLED. The state of a queue is stored in the queue’s state; after calling this method it will be set to RUNNING. WARNING: Resuming many high-QPS queues at the same time can lead to target overloading. If you are resuming high-QPS queues, follow the 500/50/5 pattern described in
Managing Cloud Tasks Scaling Risks.
Sets the access control policy for a Queue. Replaces any existing policy. Note: The Cloud Console does not check queue-level IAM permissions yet. Project-level permissions are required to use the Cloud Console. Authorization requires the following
Google IAM permission on the specified resource parent: *
cloudtasks.queues.setIamPolicyCreates and buffers a new task without the need to explicitly define a Task message. The queue must have HTTP target. To create the task with a custom ID, use the following format and set TASK_ID to your desired ID: projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks/TASK_ID:buffer To create the task with an automatically generated ID, use the following format: projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks:buffer.
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.
Deletes a task. A task can be deleted if it is scheduled or dispatched. A task cannot be deleted if it has executed successfully or permanently failed.
Gets a task.
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.
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’s target, then the task will be deleted; otherwise the task’s schedule_time will be reset to the time that RunTask was called plus the retry delay specified in the queue’s RetryConfig. RunTask returns NOT_FOUND when it is called on a task that has already succeeded or permanently failed.
Returns permissions that a caller has on a Queue. If the resource does not exist, this will return an empty set of permissions, not a NOT_FOUND error. Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may “fail open” without warning.
Creates or Updates a CMEK config. Updates the Customer Managed Encryption Key assotiated with the Cloud Tasks location (Creates if the key does not already exist). All new tasks created in the location will be encrypted at-rest with the KMS-key provided in the config.
A builder providing access to all methods supported on
project resources.
It is not used directly, but through the
CloudTasks hub.
Request message for PurgeQueue.
QueryOverride. Query message defines query override for HTTP targets.
A queue is a container of related tasks. Queues are configured to manage how those tasks are dispatched. Configurable properties include rate limits, retry options, queue types, and others.
Rate limits. This message determines the maximum rate that tasks can be dispatched by a queue, regardless of whether the dispatch is a first task attempt or a retry. Note: The debugging command, RunTask, will run a task even if the queue has reached its RateLimits.
Request message for ResumeQueue.
Retry config. These settings determine when a failed task attempt is retried.
Request message for forcing a task to run now using RunTask.
Request message for SetIamPolicy method.
The
Status type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by
gRPC. Each
Status message contains three pieces of data: error code, error message, and error details. You can find out more about this error model and how to work with it in the
API Design Guide.
A unit of scheduled work.
Request message for TestIamPermissions method.
Response message for TestIamPermissions method.
URI Override. When specified, all the HTTP tasks inside the queue will be partially or fully overridden depending on the configured values.
