Ooredoo M-Faisa API Documentation

Reverse-engineered from traffic captures and live Frida hooks of the official Ooredoo SuperApp (com.mventus.ooredoomaldives).

Overview

M-Faisa is Ooredoo Maldives' mobile wallet, exposed via a JSON/form-encoded REST API on superapp.ooredoo.mv. The wire format is unusual in three ways:

Field-level RSA encryption. The MSISDN (mdnId, mobileNumber, userName, initiatingMDN, identifier) and the mPIN (mPin) are each encrypted with a different RSA public key before being placed in the request body. See 01-encryption.md.
Anti-replay envelope. Every session-scoped form-encoded POST carries an rndValue (RSA-encrypted timestamp) and a csValue (Adler32 of formDataJson + nonceStr). See 01-encryption.md → rndValue / csValue.
Cloudflare-fingerprinted header order. A User-Agent header sent explicitly (instead of letting OkHttp add it last) returns HTTP 400.

Base URL

All M-Faisa endpoints are mounted at /api/mfaisaa-bff/mfino/v1.1/web/....

Authentication Model

Value	How obtained	How used
`loginExchangeKey`	Returned by `doMobileLogin` on success	Held in memory only; identifies the session
Session timeout	`mobileLoginSessionTimeout` field, default 240 seconds	After expiry the user must re-login (no refresh-token flow)

Because there is no refresh, Thijooree re-runs fetchSubscriberByMDN + doMobileLogin on every cold-start refresh, using the saved msisdn + mPIN from CredentialStore. The SESSION_EXPIRED error envelope is also caught at runtime and the session is silently re-established before retrying the failed request.

Common Request Headers

Content-Type: application/json; charset=UTF-8           (fetchSubscriberByMDN)
Content-Type: application/x-www-form-urlencoded         (every other endpoint)
Host: superapp.ooredoo.mv
Connection: Keep-Alive
Accept-Encoding: gzip
User-Agent: okhttp/4.12.0

Do NOT set User-Agent in code. Cloudflare fingerprints the header order; an explicit User-Agent header is pushed to the front of the request and the request is rejected with HTTP 400. Let OkHttp's BridgeInterceptor add the default okhttp/4.12.0 at the end.
