How it works

Architecture and functionality: How it works

Two payment flows that the gateway supports through one integration.

1. Online invoice payment

The project sends a request with its X-Project-Key, Somonly creates an invoice in SmartPay, the customer pays via payment_link or a deeplink in their banking app, and the project receives a signed webhook with retries.

2. Account-number payment

The customer finds the service in Alif Mobi or another bank and enters an account number. SmartPay sends a check or pay request, Somonly identifies the project by the account prefix (for example, 104 for "TV CRM") and proxies the answer back to the banking app.
