Include this token in the `Authorization: Bearer ` header on every call. Tokens expire and must be refreshed. Use the optional `ApiEndpoint` field to scope a token to a specific endpoint URL for tighter security. **What this does:** Returns a `token` string and `tokenExpiry` timestamp. Include the token as `Authorization: Bearer ` on every subsequent request. The optional `ApiEndpoint` field scopes the token to a single endpoint URL — a token scoped to `/v1.0/numbers/provision` will be rejected by any other endpoint. Re-authenticate from scratch when a token expires; there is no refresh mechanism. **Next steps:** - Use the token on any other endpoint — `POST /v1.0/numbers/provision`, `POST /v1.0/message/outbound`, etc. ## OpenAPI ````yaml /api-reference/openapi.json post /v1.0/OAuth2/tokens openapi: 3.0.3 info: title: mPaaS Core APIs version: 1.0.8 description: >- The Telegent mPaaS (Mobile Platform as a Service) API gives you full programmatic control over mobile phone numbers, messaging, voice routing, subscribers, and account management.
