Click on Buyer from the left sidebar, select API Integration, and click the Edit icon next to any integration to open its settings.

Click on the Field Mapping tab at the top of the API Integration edit page.

Click on the Post Method dropdown to see all available methods for sending lead data to the buyer. The following methods are available:

• HTTP POST Method — sends lead data as a standard HTTP POST request to the buyer’s endpoint
• JSON Method — sends lead data in JSON format via API — commonly used for modern REST API integrations
• XML Method — sends lead data in XML format via API — used for buyers that require XML based integrations
• Google Sheet — posts lead data directly into a connected Google Sheet — useful for buyers who manage leads in spreadsheets
• Zoho Leads — sends lead data directly into Zoho CRM as a new lead record
• Static File — delivers lead data as a static file to the buyer’s specified location

After selecting the Post Method, fill in the Authorize Header and cURL Username & Password fields if the buyer’s API requires authentication to accept lead data.

Map your system’s lead fields to the buyer’s API fields in the Post data using API section below — such as Applicant First Name, Last Name, Email, Phone, and more. Once all fields are mapped, click Save to apply the configuration.
