1. API Description

Domain name for API request: mps.tencentcloudapi.com.

This API is used to parse the content of an MPS event notification from the msgBody field in the message received from CMQ.
Instead of initiating a video processing task, this API is used to help generate SDKs for various programming languages. You can parse the event notification based on the analytic function of the SDKs.

A maximum of 20 requests can be initiated per second for this API.

We recommend you to use API Explorer

Try it

API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

2. Input Parameters

The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

Parameter Name	Required	Type	Description
Action	Yes	String	Common Params. The value used for this API: ParseNotification.
Version	Yes	String	Common Params. The value used for this API: 2019-06-12.
Region	No	String	Common Params. This parameter is not required for this API.
Content	Yes	String	Event notification obtained from CMQ.

3. Output Parameters

Parameter Name	Type	Description
EventType	String	The event type. Valid values: WorkflowTask EditMediaTask ScheduleTask (scheme)
WorkflowTaskEvent	WorkflowTask	The information of a video processing task. Information will be returned only if `EventType` is `WorkflowTask`. Note: This field may return null, indicating that no valid values can be obtained.
EditMediaTaskEvent	EditMediaTask	The information of a video editing task. Information will be returned only if `EventType` is `EditMediaTask`. Note: This field may return null, indicating that no valid values can be obtained.
SessionId	String	The ID used for deduplication. If there was a request with the same ID in the last seven days, the current request will return an error. The ID can contain up to 50 characters. If this parameter is left empty or an empty string is entered, no deduplication will be performed.
SessionContext	String	The source context which is used to pass through the user request information. The task flow status change callback will return the value of this field. It can contain up to 1,000 characters.
ScheduleTaskEvent	ScheduleTask	The information of a scheme. Information will be returned only if `EventType` is `ScheduleTask`. Note: This field may return null, indicating that no valid values can be obtained.
Timestamp	Integer	- The expiration time (Unix timestamp) of the notification's signature. - By default, notifications sent by MPS expire after 10 minutes. If the expiration time specified has elapsed, a notification will be considered invalid. This can prevent replay attacks. - The format of this parameter is a decimal Unix timestamp, i.e., the number of seconds that have elapsed since 00:00 (UTC/GMT time) on January 1, 1970.
Sign	String	The notification signature. Sign = MD5 (Timestamp + NotifyKey) MPS concatenates `Timestamp` and `NotifyKey` in `TaskNotifyConfig` and calculates a signature using the MD5 algorithm. This signature is included in the notification sent to your backend server. If the signature in the notification matches your own calculation result, it indicates that the notification is from MPS.
RequestId	String	The unique request ID, which is returned for each request. RequestId is required for locating a problem.
