Outbound — call an external API

The Webhook action sends a POST (or GET/PUT/DELETE) to any URL with headers and a body you define. Use it to push data to Slack, Zapier, Make, your own backend, or any service with an HTTP API.

Inbound — trigger a workflow from elsewhere

  1. 1
    Trigger: Inbound Webhook
    Open Doors generates a unique URL.
  2. 2
    Copy the URL
    Paste it into whatever system needs to fire the workflow.
  3. 3
    Send a test payload
    Open Doors captures the shape of the data and lets you map it to contact fields.
