Moosyl is the Masrvi API for developers: create a payment, your customer pays in Masrvi, and your system is notified the moment it’s paid.

Masrvi is the banking app of BMCI. Moosyl connects you to it — and to every other Mauritanian bank app.
Your server creates a checkout session or payment request through the Moosyl API.
They choose Masrvi at checkout and confirm the payment in the app they already use.
Moosyl sends a signed payment-updated webhook the moment the payment is completed.
The same call accepts Masrvi and every other supported bank app.
