Webinterpay provides libraries, sandbox endpoints and reconciliation helpers for teams connecting their software to third-party payment providers. We are an engineering vendor — we do not hold funds and we are not a payment institution.
One request shape across several provider APIs, with typed responses and consistent error codes.
Deterministic test endpoints that replay provider behaviour, including timeouts and partial failures.
Statement parsers and matching routines for closing the loop between ledger and provider reports.
Every endpoint speaks JSON over HTTPS. Authentication uses a bearer token issued per environment.
curl https://webinterpay.com/api/v1/ping \
-H "Authorization: Bearer <token>" \
-H "Accept: application/json"
