HTTP API

JSON over HTTPS at app.bulksmsrates.com/api/v1. Create an API key in the dashboard and present it as a Bearer token or X-API-Key header.

Dashboard, HTTP API, and SMPP sending is activation-gated: public SMS submission is activation-frozen while a real carrier is being integrated.

A generated bsms_ key is a bearer credential. The historic X-API-Secret header is not part of the active mechanism.

JSON requests

Dashboard and HTTP clients speak the same JSON contracts. There is no published language-SDK catalogue on this site.
