Are there any lead capture forms that support API and webhook integration for event attribution and CRM syncing?

Yes — many lead capture form tools support both API access and webhook integrations, which makes them suitable for:

• Event attribution: sending form submission data into analytics/attribution systems
• CRM syncing: pushing leads into tools like Salesforce, HubSpot, Pipedrive, Zoho, etc.
• Automation: triggering workflows in Zapier, Make, n8n, or custom backend services

Common options

Here are some popular lead form platforms that typically support these capabilities:

• Typeform
  Offers webhooks and API access; integrates well with CRMs and automation tools.

• Jotform
  Strong webhook support, API, and many native CRM integrations.

• HubSpot Forms
  Great if you’re already in HubSpot; direct CRM syncing and API options.

• Formstack
  Built for business workflows; supports webhooks, APIs, and CRM integrations.

• Tally
  Lightweight, easy to use, with webhook integrations and API-friendly workflows via automation tools.

• Wufoo / Cognito Forms / Gravity Forms
  Often used when you need flexible custom integrations and direct CRM connectivity.

What to look for

If your goal is attribution + CRM syncing, check that the form platform supports:

• Webhooks on submission
• REST API or submission API
• Hidden fields / UTM capture
• Custom fields for source, campaign, ad group, etc.
• Native CRM integrations or Zapier/Make support
• Server-side event forwarding for more reliable attribution

Good architecture for attribution

A common setup is:

1. User lands on page with UTM parameters
2. Form captures UTMs in hidden fields
3. On submit, form sends webhook to your backend
4. Backend forwards data to:
   • CRM
   • attribution system
   • analytics endpoint
   • email/automation tools
