Integrations
We don't sell generic third-party connectors — we offer three real integration points that you wire straight into your own backend or CRM.
REST API for your own backend
Send SMS, WhatsApp and push directly from your code, with OAuth2 client_credentials authentication and a short-lived JWT.
See the API reference →WhatsApp webhook
Receive delivery events and customer replies back through a webhook verified with your Meta token.
See the technical detail →Templates & automated workflows
Define a template once per channel and trigger it from the panel or the API; workflows tie an event to a sequence of sends across channels.
