Integrate Seedance 2.5 in Six Steps
1
1. Create and Protect an API Key
Create a GoEnhance key and send bearer authorization only from trusted server-side code.
2

4. Submit the Async Task
POST JSON to
https://api.goenhance.ai/api/v1/videos/generations and confirm application-level success. 5
5. Persist img_uuid
Store
data.img_uuid before the request handler exits so retries and status checks refer to the same task. 6
6. Handle the Terminal Result
Poll
GET /api/v1/jobs/detail or process HTTPS callbacks idempotently, then review the returned video before release.Use authorized prompts and source images, then evaluate motion, continuity, audio, and subject fidelity before shipping.
