What this sandbox does and does not test
It demonstrates request fields, validation errors, A2P duplicate-request handling and selected response states. Spend-limit validation is a local preview only; it does not submit a billing request. The 403 scenarios are fixed examples, not token verification or live policy evaluation. A2P accepts only the fixed demo scope and reserved fictional number +12025550123. It keeps at most 100 messages in memory.
Responses are illustrative and include simulator-only fields. Pricing, encoding/segment calculation, batch processing, OTP feedback, OAuth, mTLS, tenant authorization, callbacks, carrier delivery and production policy execution are not implemented here. No certification or production compatibility is implied.
Updated 14 September 2026. Source basis: partner contracts, A2pMessageController and the API billing validation changes under qualification. Live access requires separately provisioned endpoints and credentials from Sovrion Labs; this page provides neither.
