Get notified in a Slack channel when someone submits your form. Needs Zapier, Make or n8n in between to format the message.

Webhook payload format
When a form is submitted, SendForm sends a POST request with the following JSON payload:

"form_id": "abc123",
"submission": {
"id": "sub_xyz789",
"form_id": "abc123",
"data": {
"Name": "John Doe",
"Email": "john@example.com",
"Message": "Hello!"
},
"created_at": "2025-01-15T10:30:00.000Z"
},
"timestamp": "2025-01-15T10:30:00.000Z"
}Security features
- •Signature verification: Add a secret to sign requests with HMAC-SHA256
- •Human-readable labels: Field data uses your labels, not internal IDs
- •Retry on failure: Failed webhooks are retried automatically (temporary failures only - 5xx, 429 or network errors)
