Developers
Every message, lead and event — in your systems too
A JSON:API over HTTPS, signed webhooks per number, and a public capture endpoint for your website forms. The same API the apps use.
# Forward every inbound message

Four ways in
REST API
Endpoints for conversations, persons, leads, broadcasts, templates and team.
Webhooks
Per-number forwarding of message and status events. Signed per attempt, retried for up to 7 days. Business events — lead created, lead stage changed, lead owner assigned, request opened or changed, payment received, order placed, form completed — from Settings → Integrations → Webhooks & events.
Lead capture
One token, one POST. Website forms, Zapier, Make — straight into the pipeline.
Auth & scopes
Session tokens for people, capture tokens for systems. Each route checks the caller’s permissions and refuses anything not allowed.
