Key Takeaways

  • Send SMS from Python with requests or httpx against REST HTTPS/JSON — not a pip “Complete SDK” product from us.
  • Bearer from environment; confirm live JSON in Developer Center.
  • Persist message ids; accept ≠ delivered.
  • You need a working Android phone with a SIM and SMS credit from your mobile operator. Operator message costs are yours—we do not sell carrier SMS balance. Service pricing is based on device count and total SMS sent through the gateway.
  • Free canaries use 300 SMS lifetime — not Unlimited SMS.

Server-side workers only. Pair phones via setup. Prefer async workers for bulk; keep OTP on a separate pool.

requests/httpx + ENV is the client. A PyPI “official SDK” is not required to ship SMS.

requests/httpx — not an SDK package

JSON body fields come from OpenAPI. Optional deviceIds for multi-device. Language samples elsewhere are PHP/C# shapes — same wire format.
