The payment ledger for The Gambia
Every dalasi,
on one live ledger.
Collections, payouts, and reconciliation across Wave, APS, and cards — one API, one source of truth for the money moving through your business.



The platform
One platform to move every dalasi.
Collections
Get paid the way your customers already pay.
Accept mobile money and cards with a single request. Wave, APS, and card checkout — localized, hosted, and reconciled for you, from the first transaction to the millionth.
Payouts
Send money to any rail, automatically.
One request per payout, queued and retried automatically if a rail wobbles. Nothing silently disappears — a payout settles, tells you why it failed, or waits for float and says so.
Built for developers
Three requests. That's the whole integration.
Plain REST and JSON — no SDK required. Amounts as decimal strings, idempotent by reference, documented in an OpenAPI spec that's checked in CI, so the docs can't drift from the API.
