asasii acceptance for developers and integrators
A merchant's developer goes from a test key to a first payment from the portal, without a ticket to the institution.
Start in the sandbox
A test key, a checkout session and the payment.succeeded webhook, against the live platform in test mode.
Keys and webhooks
Scoped keys that rotate with an overlap window, and signed webhooks retried with backoff and replayable from the portal.
Every call on the record
A request log with the idempotency key on each call, so a duplicate order is explained without a ticket, and an event log with each delivery to each endpoint.
SDKs and versions
Embedded checkout SDKs for web, iOS and Android, server SDKs for Node and Python, and API versions pinned per key.
