Open Platform · open.atasuai.com

One Open API,
connect to all of Atasuai.

A unified way to connect, one set of conventions, and one place for documentation — partners and developers integrate with Atasuai's modules according to their own permissions. Delivery is in pre-release, and the rest are coming online.

Why everything is unified at open.atasuai.com

Not a pile of scattered endpoints crammed under one domain — but a truly unified foundation.

Unified authentication, least privilege

All modules share one OAuth 2.0 way to connect, but each partner receives only the scopes they should have — delivery partners get only deliveries:*, sellers get only orders:*, with no overreach.

Consistent conventions

All modules share the same specification: versioned paths, idempotency keys, cursor pagination, RFC 7807 errors, and HMAC-signed webhooks. Learn it once, apply it everywhere.

One place for docs and a sandbox

Unified developer documentation, an interactive API reference, and an isolated sandbox at sandbox.open.atasuai.com (Planned, certificate not yet ready). Every new module launches right here.

Unified access, authorized as needed.

Create API credentials in the partner back office, or have an Atasuai account manager enable them during onboarding — you are only authorized to access the modules that match your identity (delivery partners cannot see order data). Agent (delivery-partner) credentials are temporarily disabled; seller credentials work normally. Integrate delivery today; when you genuinely need more modules, add the corresponding scopes to your credentials later.
