Webhooks push data to your URL when events happen, instead of you polling. Lower latency, lower API usage.

  1. 1
    Settings → API → Webhooks → New
    Enter your endpoint URL.
  2. 2
    Pick events
    Contact created, opportunity moved, invoice paid, etc.
  3. 3
    Set secret
    Open Doors signs every payload with HMAC-SHA256 using this secret. Verify on your end.
  4. 4
    Test
    Send a test payload from the UI; confirm your endpoint returns 200.
