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 parameters

Parameter	Type	Required	Description	Example
VideoId	string	No	The audio or video ID. You can obtain the ID by using one of the following methods: For audio or video files uploaded through the console, log on to the ApsaraVideo VOD console and choose Media Files > Audio/Video to view the video ID. Obtain the video ID from the VideoId parameter returned by the CreateUploadVideo operation when you request an upload URL and credential. After the video is uploaded, call the SearchMedia operation to query the audio or video ID, which is the value of VideoId in the response.	1f1a6fc03ca04814031b8a6559e****
AuthTimeout	integer	No	The validity period of the signature for FileURL (source file URL). Unit: seconds. Default value: 3600. The minimum value is 1. If OutputType is set to cdn: FileURL expires periodically only if URL signing is enabled. Otherwise, FileURL is permanently valid. Minimum value: 1. Maximum value: unlimited. Default value: 3600 if this parameter is not specified. If OutputType is set to oss: FileURL expires periodically only if the storage permission is set to private. Otherwise, FileURL is permanently valid. Minimum value: 1. Maximum value: To reduce security risks to the origin server, the maximum value is 2592000 (30 days) when the audio or video file is stored in a bucket managed by ApsaraVideo VOD, and 129600 (36 hours) when the file is stored in your own OSS bucket. Default value: 3600 if this parameter is not specified.	3600
OutputType	string	No	The type of the output URL. Valid values: oss: back-to-origin URL. cdn (default): CDN URL. Note If the bucket type of the source file is in, only the OSS URL is returned.	oss
AdditionType	string	No	The type of additional information. Separate multiple values with commas (,). By default, only basic information is returned. Valid values: video: video stream information. audio: audio stream information.	video
ReferenceId	string	No	The custom ID. Only lowercase letters, uppercase letters, digits, hyphens (-), and underscores (_) are supported. The value must be 6 to 64 characters in length and is unique at the user level.	123-123
