Send leads from Blastform API to Zapier

🎯 General principle

When a form is submitted, the data is automatically sent to the configured URL as an HTTP POST request with information in JSON format.

Each form has its own configuration. To set it up: Settings → API Lead Configuration.

📸 Configuration interface

The API Lead Configuration page has 3 main areas:

1. URL* The address to send data to (required).
2. Secret key (Bearer Authentication): Used to secure the transmission (sent in headers).
3. Field mapping: Correspondence between your form fields and JSON names.

• Left column: The form field (e.g. Last name, Email, Mobile phone)
• Right column: The name to be sent as JSON (e.g. name, email, mobile_phone)

1. Secret key (body): Optional key sent in the request body.

💡 You can add as many mappings as you need with the + Add field button.
