Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request syntax

POST /2023-03-30/functions/{functionName}/invocations HTTP/1.1

Path Parameters

Parameter	Type	Required	Description	Example
functionName	string	Yes	The function name.	my-func

Request parameters

Parameter	Type	Required	Description	Example
qualifier	string	No	The function version or alias.	LATEST
x-fc-invocation-type	string	No	The function invocation type. Valid values: Sync and Async.	Sync
x-fc-log-type	string	No	The type of log to return for the function invocation. Valid values: None and Tail.	Tail
body	string	No	The function invocation parameters.	event
x-fc-async-task-id	string	No	The ID of the asynchronous task. You must enable the asynchronous task feature to use this parameter. Note When you use an SDK, set this parameter to a business-related ID. This helps you manage the task execution. For example, a video processing function can use the video filename as the invocation ID. Use this ID to check whether the video is processed or to stop the processing task. The ID must start with a letter or an underscore (_). It can contain letters, digits, underscores (_), and hyphens (-). The ID can be up to 128 characters long. If you do not specify an ID for an asynchronous invocation, the system automatically generates one.	test-id

Response elements
