This change adds one entry only; existing facilitators remain unchanged.
Integration update — 9 October 2026
Capabilities remain public. POST /verify and POST /settle require a merchant API key through X-API-Key or Authorization: Bearer. Unauthenticated empty requests were checked and return HTTP 401. Integration guide: https://facilitator-xpay.llc/docs
The proposed listing has been corrected to match these requirements. No new paid transaction was executed; an authenticated end-to-end settlement test is still pending.
