Architecture

Messaging architecture: REST or SMPP in, delivery reports back

Two ways to submit traffic, one routing layer, and delivery reports for both.

A2P SMS architecture Submit messages over REST (JSON over HTTPS) or bind over SMPP 3.4. Each message returns a message ID and is routed per destination and message type with your registered sender ID, with rate limits and geo-restrictions on by default. Operators deliver to the handset; delivery reports come back to your webhook for REST traffic, or as deliver_sm PDUs on your SMPP bind.
