Webhooks

Send form data to any URL endpoint via HTTP POST. Webhooks enable you to connect Web3Forms with thousands of applications and services, creating powerful automation workflows without writing code.

This is a PRO feature. You must have an active PRO plan subscription to use this feature.

What are Webhooks?

Webhooks allow you to automatically send form submission data to any HTTP endpoint in real-time. This opens up endless possibilities for integrating with:

  • Automation Platforms: Zapier, Make (Integromat), n8n, Pipedream

  • CRM Systems: Salesforce, HubSpot, Pipedrive

  • Email Marketing: Mailchimp, ConvertKit, SendGrid

  • Project Management: Asana, Trello, ClickUp

  • Databases: Airtable, MongoDB, PostgreSQL

  • Communication: Slack, Discord, Microsoft Teams

  • Custom Applications: Your own backend services

Key Features

  • ✅ Universal Compatibility: Works with any service that accepts HTTP POST requests

  • ✅ Real-time Delivery: Data is sent immediately after form submission

  • ✅ Secure Transmission: Data is sent over HTTPS

  • ✅ Automatic Retry: Failed webhooks are retried automatically

  • ✅ Clean Payload: Sensitive data is removed before sending

Setup Instructions

Step 1: Create a Webhook URL

Webhook URLs can be created using various platforms:

Recommended Platforms:

  • Zapier - Connect with 5,000+ apps (Commercial)

  • Make (formerly Integromat) - Advanced automation (Free tier available)

  • Pipedream - Developer-friendly automation (Generous free plan)

  • n8n - Open-source automation (Self-hosted or cloud)

We recommend Pipedream if you're technical, as it offers a generous free plan and provides excellent debugging tools.

Step 2: Access the Integrations Tab

  1. Log in to your Web3Forms Dashboard

  2. Select the form you want to connect

  3. Navigate to the Integrations tab in your form settings

Step 3: Enable Webhook Integration

Testing Your Webhook

Test in Web3Forms

  2. Check if the webhook was triggered

  3. Verify data arrived at your endpoint

Debug with Webhook Testing Tools

Use these tools to inspect webhook payloads:

Check Delivery Status

Monitor webhook delivery in your automation platform:

  • Check execution logs in Zapier/Make/Pipedream

  • Review error messages if delivery fails

  • Verify payload structure matches expectations

Troubleshooting

Webhook Not Triggering

  • Verify URL: Ensure the webhook URL is correct and accessible

  • Check Status: Make sure the integration is enabled (toggle on)

  • Test Endpoint: Use webhook testing tools to verify your endpoint works

  • Check Logs: Review logs in your automation platform

  • Firewall: Ensure your endpoint isn't blocked by a firewall

Invalid URL Error

  • Webhook URL must start with https://

  • URL must be publicly accessible

  • Don't include spaces or invalid characters

  • Test the URL in a browser or curl command

Data Not Received

  • Check the payload structure in your automation platform

  • Verify field names match what you expect

  • Ensure your endpoint is processing JSON correctly

  • Check for rate limits on your receiving service

Timeout Errors

  • Webhook endpoints must respond within 30 seconds

  • If processing takes longer, return 200 OK immediately

  • Process data asynchronously in the background

Advanced Configuration

Multiple Webhooks

To send data to multiple endpoints:

  1. Use one webhook URL in Web3Forms

  2. Configure your automation platform to forward to multiple services

  3. Example: Zapier → Send to both Slack and Airtable

Data Transformation

Transform data before sending to your destination:

  • Use automation platforms to map and modify fields

  • Filter submissions based on conditions

  • Enrich data with external API calls

  • Format data for specific integrations

Conditional Logic

Send to different endpoints based on form data:

  • Use automation platforms to add conditional routing

  • Example: Send enterprise leads to sales team, others to support

  • Filter spam or test submissions

Error Handling

Handle webhook failures gracefully:

  • Set up retry logic in your automation platform

  • Create error notifications for failed webhooks

  • Log failures for debugging

  • Implement fallback endpoints

Security Best Practices

Protect Your Webhook URLs

  • Never share webhook URLs publicly

  • Regenerate URLs if compromised

  • Use URL parameters for authentication if supported

  • Monitor webhook activity for unusual patterns

Validate Incoming Data

In your webhook handler:

  • Validate data types and formats

  • Sanitize input to prevent injection attacks

  • Check for required fields

  • Implement rate limiting

Use HTTPS

  • Always use HTTPS endpoints

  • Never use HTTP for webhooks

  • Ensure SSL certificates are valid
