What you can build

One API for money coming in, money going out, and everything needed to account for both.

Charge a customer's mobile wallet. They approve on their phone; you get a confirmed status rather than an assumption.

Send money to a mobile wallet. Available funds are checked before submission, so a payout never leaves against a balance that is not there.

Refund all or part of a successful collection. A refund is its own transaction, linked to the original and capped at what remains refundable.

A page we host and you send the customer to. They pick their operator and enter their number, so you never handle it yourself.

HMAC-signed notifications, retried with growing delays, and redeliverable by hand from the dashboard. Every event stays available to poll as well.

Your transactions and their full history, balances, API keys, team and the webhook delivery log — in French or English.
