Developers
API overview
Send OTPs, alerts, and session messages from your own product. Credentials are issued when the channel is activated — this page is the map, not a live key.
Send an approved template, then continue the 24-hour session with text, media, and buttons. Inbound replies arrive on your webhook.
RCS and voice
Rich cards use the same contact record. Voice OTP and IVR calls are requested per number and billed per pulse.
Webhooks
Subscribe to sent, delivered, read, and failed events so your CRM stays in step with the inbox.
