Every form has a unique endpoint URL, shown in the form’s Setup tab. Create more forms from the dashboard with New Form.abc123def456) is the form’s slug.
4. Point your HTML form at the endpoint
{ "success": true, "message": "Submission received" }.
5. Configure integrations
Open the form’s Integrations tab and connect:Resend

A new row for every submission
Webhook

The SDK renders forms you design in the form’s Builder tab:formId is the form’s slug. The form needs a schema saved in the Builder tab; a form without one renders nothing.
