You can subscribe to different event types and receive notifications when forms are submitted or updated. Configure webhooks to subscribe to form events with the Formo API.

​

Base URL

All Forms API requests should be made to:

https://api.formo.so/api

​

Finding Your Form ID

Before setting up webhooks, you’ll need your Form ID. To locate it:

1. Click on the form you want to track
2. Navigate to Settings
3. Select General from the sidebar
4. Find and copy your Form ID from the displayed information

​

Available Webhook Events

• FORM_SUBMISSION: Triggered when a user submits a form
• FORM_UPDATED: Triggered when a form is updated

​

Managing Webhooks

​

Creating Webhooks

To create a new webhook subscription, use the Subscribe to Webhook endpoint.

​

Listing Webhooks

To view all your webhook subscriptions for a form, use the List Webhooks endpoint.

​

Removing Webhooks

To remove a webhook subscription, use the Unsubscribe from Webhook endpoint.

​

Event Payload

When an event occurs, Formo will send a POST request to your webhook URL with the following payload structure:

{
	"formId": "string",
	"formTitle": "string",
	"submissionId": "string",
	"submittedAt": "string"
	// Form field data with transformed values
}

​

Best Practices

1. Verify Requests: Always validate that requests are coming from Formo by checking the API key
2. Handle Retries: Implement retry logic in case your endpoint is temporarily unavailable
3. Process Asynchronously: Handle webhook events asynchronously to prevent timeouts
4. Monitor Events: Keep track of webhook delivery status for debugging
