  title: Telkomsel DigiHub APIs Consent Management USSD API
  description: Consolidated OpenAPI for the API products Telkomsel exposes to developers and enterprises through DigiHub (https://digihub.telkomsel.com), Telkomsel's API marketplace. Paths, methods, parameters, schemas, and examples are taken verbatim from DigiHub's own published per-endpoint OpenAPI documents (served publicly at https://digihub.telkomsel.com/apis/V2/endpoint/{id}); $refs were inlined and the per-endpoint documents merged into one file. Most APIs authenticate with an api_key header plus an x-signature header of SHA256(API Key + Secret Key + epoch timestamp); the CAMARA-style SIM Swap API uses OIDC CIBA (/bc-authorize + /token) with a bearer token. Calling any of these endpoints requires a DigiHub account and a subscribed plan (sandbox, quota, tier, or PAYU); enterprise plans require an NDA or commercial contract.
