SMPP API

The Twilio Short Message Peer-to-Peer (SMPP) API enables you to send and receive SMS messages over Twilio using the SMPP protocol(link takes you to an external page).

With the SMPP API, you can send outbound messages, and receive final delivery receipts across all Twilio-supported sender types, including short code, long code, toll-free, 10DLC, and alphanumerics numbers. This capability is available across all markets supported by Twilio.

Twilio's SMPP integration also supports receiving inbound messages, known as Mobile Originated (MO) messages, for supported short code and long code inventories in supported markets.

Twilio's system handles high message volumes, provides monitoring tools, and automatically selects the best path for sending your messages across Twilio's global network.
