Connect Your Waivers to Everything
When a waiver is signed, the data should flow where you need it — your CRM, your spreadsheet, your team chat, your booking system. Happy Waiver integrates with 7,000+ apps through Zapier and webhooks.
How It Works
A waiver is signed
A customer signs your waiver on any device — phone, tablet, kiosk, or computer.
Webhook fires instantly
Happy Waiver sends the signer data, form fields, and document info to your configured endpoints in real time.
Zapier routes it anywhere
Zapier catches the webhook and sends the data to Google Sheets, Slack, your CRM, email platform, or any of 7,000+ apps.

Frequently Asked Questions
How does Happy Waiver integrate with Zapier?
Happy Waiver sends a real-time webhook every time a waiver is signed. Zapier catches this webhook and can route the data to any of 7,000+ connected apps — Google Sheets, Slack, Mailchimp, HubSpot, Salesforce, and more. No coding required.
What data is sent when a waiver is signed?
The webhook includes the signer's name, email, phone, birthday, all custom form fields, the document name, signing timestamp, tags, and a direct link to view the submission in your dashboard.
Is the webhook integration secure?
Yes. Every webhook payload is signed with HMAC-SHA256 using a unique signing key per endpoint. You can verify the signature to confirm the payload was sent by Happy Waiver and was not tampered with.
How many webhook endpoints can I create?
The number of webhook endpoints depends on your plan: Launch (2 endpoints), Scale (5 endpoints), Elevate (20 endpoints). Each endpoint can subscribe to multiple event types.
Do I need to know how to code?
