}Query Task Status
After submitting a task, use the unified query endpoint to check progress and retrieve results:Get Task Details
Learn how to query task status and retrieve generation results
For production use, we recommend using the
callBackUrl parameter to receive automatic notifications when generation completes, rather than polling the status endpoint.Related Resources

Common API
Check credits and account usage
Authorizations
All APIs require authentication via Bearer Token.
Get API Key:
- Visit API Key Management Page to get your API Key
Usage: Add to request header: Authorization: Bearer YOUR_API_KEY
Note:
- Keep your API Key secure and do not share it with others
- If you suspect your API Key has been compromised, reset it immediately in the management page
Body
application/json
The model name to use for generation. Required field.
- Must be
kling/v2-1-master-text-to-videofor this endpoint
Available options:
kling/v2-1-master-text-to-video Example:
"kling/v2-1-master-text-to-video"
The URL to receive generation task completion updates. Optional but recommended for production use.
- System will POST task status and results to this URL when generation completes
- Callback includes generated content URLs and task information
- Your callback endpoint should accept POST requests with JSON payload containing results
- Alternatively, use the Get Task Details endpoint to poll task status
- To ensure callback security, see Webhook Verification Guide for signature verification implementation
Example:
"https://your-domain.com/api/callback"
