Suno API Workflow Guide
If you are building with the Suno API, the biggest integration question is usually not “can Suno generate a song?” It is “which Suno endpoint should my app call first, and what should happen next?” This guide maps the main Suno API workflows on TTAPI so you can choose the right path for your product.Choose the right Suno starting point
| Goal | Best entry point |
|---|---|
| Generate a full song from a prompt | Suno Music API |
| Write lyrics before generation | Suno Lyrics API |
| Start from a reference file or source audio | Suno Upload API |
| Continue an existing track | Suno Extend API |
| Restyle or reinterpret a song | Suno Cover API |
| Split vocals and backing audio | Suno Stems API |
| Retrieve async job status and results | Suno Fetch V2 API |
The main Suno workflows
Prompt to song
This is the standard workflow for teams starting from an idea, theme, or prompt.- Optionally create lyrics through the Suno Lyrics API.
- Submit the song through the Suno Music API.
- Poll Fetch V2 or receive a
hookUrlcallback. - Continue with Extend, Cover, WAV export, or Stems.
Upload to downstream processing
Use this path when the workflow starts from existing vocals, a demo, or reference audio.- Upload the source file with the Suno Upload API.
- Pass the uploaded asset into the next Suno workflow.
- Fetch the result through Suno Fetch V2.
Extension and post-processing
Use this path when the first song draft is good and you want to improve or expand it.- Use Suno Extend to continue a track.
- Use Suno Cover to restyle an existing song.
- Use Suno Stems or Suno Stems All for separation workflows.
- Use Suno WAV when higher-quality delivery matters.
Which endpoint should come first?
| You already have… | Recommended first call |
|---|---|
| Only a concept or prompt | Suno Music API |
| A theme but no lyrics | Suno Lyrics API |
| A source file or voice reference | Suno Upload API |
| A promising song you want to continue | Suno Extend API |
| A song you want to reinterpret | Suno Cover API |
Common workflow mistakes
- Starting with Suno Music when the real asset is already an uploaded audio reference
- Treating submit endpoints as if they return final media immediately
- Using the older Fetch pattern instead of Fetch V2 for new integrations
- Forgetting to store
jobIdfor polling or retry logic - Calling stems too early when the final song has not finished processing
