v1.0.0 · public preview

Payments infrastructure,
built for developers.

Accept cards, mobile money and bank transfers with a single REST API. Hosted checkout keeps you out of PCI scope, and every response is boringly predictable.

Everything you need

SAQ-A ready

Card capture happens on the bank's hosted page. Card numbers never touch your servers or ours.

Reliable webhooks

HMAC-signed, exponential backoff retries, replay from the dashboard.

Idempotency built-in

Every mutating endpoint accepts an idempotency key so retries are safe.
