API / Webhooks
Use the developer path for SMS API documentation, Sandbox planning and webhook target notes.
Trial
Use the developer path for SMS API documentation, Sandbox planning and webhook target notes.
Use the no-code path for campaign planning, lists, validation and production readiness context.
Use the carrier-style path for a separate commercial discussion. SMPP does not automatically create Trial production access.
A sandbox API key is target account behavior. The current website does not issue keys, balances or live test sends.
Production sending requires confirmed account state, billing, sender and country readiness, consent controls and anti-abuse checks.
