Build on Petunia.

For MVP launch, Petunia’s APIs are used primarily by the product itself and a small set of partner integrations. Public, self-serve API access is coming soon.

Docs available

Public API: Coming soon

Swagger UI: Signed-in / internal

Interactive API explorer

Signed-in

Swagger UI is available inside the app environment for internal + partner use.

Note: API docs and many endpoints require an authenticated session or partner access.

Public API

Coming soon

We’re productizing a stable public API (keys, scopes, quotas, versioning). If you need early access, contact us—happy to set up a partner integration.

Webhooks

Webhooks are the preferred integration surface for many providers (signature auth + idempotency).
