Authorization Information

Each account has all the permissions required to call all APIs, but IAM users must be assigned the required permissions.

If you are using role/policy-based authorization, see Permissions Policies and Supported Actions for details on the required permissions.

If you are using identity policy-based authorization, the following identity policy-based permissions are required.

Action	Access Level	Resource Type (*: required)	Condition Key	Alias	Dependencies
apig:asyncTask:get	Read	instance *	g:ResourceTag/<tag-key>	apig:apis:export apig:apis:import	apig:instance:get

URI

GET /v2/{project_id}/apigw/instances/{instance_id}/async-tasks/{task_id}

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID. For details about how to obtain it, see Obtaining a Project ID.
instance_id	Yes	String	Gateway ID, which can be obtained from the gateway information on the APIG console.
task_id	Yes	String	Asynchronous task ID.

Request Parameters

**Table 2** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	User token. It can be obtained by calling the IAM API used to obtain a user token. The value of X-Subject-Token in the response header is a token.

**Table 3** Response body parameters
Parameter	Type	Description
task_id	String	Task ID.
task_status	String	Asynchronous task status. waiting: The asynchronous task is waiting to be processed. processing: The asynchronous task is being processed. succeeded: The asynchronous task is complete. failed: The asynchronous task failed.
