Merchant Onboarding
Create your account, get credentials, sign requests, and go live end to end.
Webhooks
Receive and verify transaction events, and optionally send inbound payment events.
How it works
1
Create your account
Register on the Faira merchant site
(web.getfaira.com/merchant/register).
You receive API credentials after signup — not via a public registration API.
2
Authenticate
Sign server-to-server checkout requests with your API secret (HMAC-SHA256).
3
Initiate checkout
Create a session, redirect your customer into Faira’s hosted flow, and let
them authorize the transaction.
4
Receive webhooks
Faira posts signed events to your endpoint as transactions change state.
