| SourceType | Yes | String | The source type. Valid values: PullLivePushLive: Live streaming PullVodPushLive: Video files PullPicPushLive: Images |
| SourceUrls.N | Yes | Array of String | The source URL(s).

To avoid push and playback issues, make sure the source files are properly interleaved. 4. Supported video coding formats: H.264, H.265. 5. Supported audio coding format: AAC. 6. Use small video files, preferably not longer than one hour. Large files may take a long time to load or resume after pause. Relay may fail if the time consumed exceeds 15 seconds. |
| DomainName | Yes | String | The push domain name. The pulled stream is pushed to this domain. Note: If the destination is not a CSS address and its format is different from that of CSS addresses, pass the full address to ToUrl. For details, see the description of the ToUrl parameter. |
| AppName | Yes | String | The application to push to. The pulled stream is pushed to this application. |
| StreamName | Yes | String | The stream name. The pulled stream is pushed under this name. |
| StartTime | Yes | String | The start time. It must be in UTC format. Example: 2019-01-08T10:00:00Z. Note: Beijing time is 8 hours ahead of UTC. The ISO 8601 format is used. |

| Operator | Yes | String | The operator. |
| PushArgs | No | String | The push parameter. This is a custom parameter carried during push. Example: bak=1&test=2 |
| CallbackEvents.N | No | Array of String | The events to listen for. If you do not pass this parameter, all events will be listened for. TaskStart: Callback for starting a task TaskExit: Callback for ending a task VodSourceFileStart: Callback for starting to pull from video files VodSourceFileFinish: Callback for stopping pulling from video files ResetTaskConfig: Callback for modifying a task TaskAlarm indicates a warning event. AlarmType examples:PullFileUnstable: Pull from video files is unstable. PushStreamUnstable: Push is unstable. PullFileFailed: Error pulling from video files. PushStreamFailed: Push error. FileEndEarly: The video file ended prematurely. |
| VodLoopTimes | No | String | The number of times to loop video files. Default value: -1. -1: Loop indefinitely 0: Do not loop > 0: The number of loop times. A task will end either when the videos are looped for the specified number of times or at the specified task end time, whichever is earlier. This parameter is valid only when the source is video files. |
| VodRefreshType | No | String | The behavior after the source video files (SourceUrls) are changed.ImmediateNewSource: Play the new videos immediately ContinueBreakPoint: Play the new videos after the current video is finished playing (the remaining videos in the old playlist will not be played). This parameter is valid only if the source before the change is video files. |
| CallbackUrl | No | String | A custom callback URL. Callbacks about pull and relay events will be sent to this URL. |
| ExtraCmd | No | String | Other parameters. For example, you can use ignore_region to ignore the region passed in and assign a region based on load distribution. |
| Comment | No | String | The remarks for a task, not longer than 512 bytes. |
| ToUrl | No | String | The complete destination URL. If you specify this parameter, make sure you pass in an empty string for DomainName, AppName, and StreamName.Note: Make sure that the expiration time of the signature is later than the task end time. |
| BackupSourceType | No | String | The backup source type. PullLivePushLive: Live streaming PullVodPushLive: Video files Notes: 1. Backup sources are supported only if the primary source type is live streaming. 2. When pull from the primary source is interrupted, the system will pull from the backup source. 3. If the backup source is a video file, each time the video is finished, the system will check if the primary source is recovered and will switch back if it is. |
| BackupSourceUrl | No | String | The URL of the backup source. You can specify only one backup source URL. |
| WatermarkList.N | No | Array of PullPushWatermarkInfo | The information of watermarks to add. Notes: 1. You can add up to four watermarks to different locations of the video. 2.

The default is 0.0: Do not use local mode 1: Use local mode Note: If you enable local mode, MP4 files will be downloaded to local storage, and the local files will be used for push. This ensures more reliable push. Pushing a local file will incur additional fees. |
| Parameter Name | Type | Description |
