Pricing: paid
Base URL: https://msgapi.threema.ch/

Last checked: 2026-07-05
Production caveat: Keep credentials server-side and confirm current limits, pricing, and webhook/error behaviour in the provider docs.

Help me set up the correct onboarding/authentication path and make the first valid request ~ explain exactly where credentials go and what must happen before production.
