Migrating a Suno API integration without breaking production
The models are similar. The things that break production are task ids, status names, media URLs and billing semantics.
Map the differences first
| Area | What to check |
|---|---|
| Auth | Bearer token vs account cookie; key rotation and scopes |
| Task id | One id per request, or one per track; where it is returned |
| Status | queued / generating / complete / failed — map every value |
| Media URL | Temporary or permanent; whether a fresh fetch is free |
| Billing | Per submit vs per track; what happens on failure |
A four-step cutover
- Shadow reads: point status checks at the new provider without submitting writes.
- Adapter layer: normalize status values and task ids behind one interface.
- Dual write: submit a small percentage to both providers and compare results.
- Cut over: move traffic in batches, keeping the old provider available for reconciliation.
What not to migrate
Do not copy account cookies, undocumented endpoints, or temporary media URLs. Re-create keys, use documented endpoints, and store task ids instead of URLs. If your old integration relied on a private web app endpoint, treat it as a rewrite, not a port.
Next: endpoint reference · error handling · task lifecycle.
常见问题 / FAQ
Can I keep the same task ids?
No. Task ids belong to the provider; store the new id alongside your own request id and reconcile by your id.
Do I need to change my prompt format?
Usually not. Keep a provider-neutral prompt and map model names and parameters in the adapter.
How long should I run both?
At least one full billing cycle or a representative batch, whichever is longer.
Is there an official Suno API? What you can actually use, and what it costs.
