Messages API
Send and track SMS
The Messages API is the general-purpose OpenSMS endpoint for outbound SMS, delivery tracking, and two-way message capture when a gateway runs in inbound mode.
What you can do
- Queue outbound SMS with your own request identifiers
- Track queued, pending, sent, delivered, failed, and received states
- List recent messages or inspect an individual message record
- Receive inbound replies through polling or signed webhooks
