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 Response Mapping tab at the top of the API Integration edit page.

On the left side, locate the Ping Response Type dropdown and select the format in which the buyer sends back their ping response.

On the right side, locate the Post Response Type dropdown and select the format in which the buyer sends back their post response. The following response types are available:

• JSON — buyer responds in JSON format — commonly used for modern REST API integrations
• XML — buyer responds in standard XML format
• XML with Attribute — buyer responds in XML format with attribute-based values instead of node values
• String/GoogleSheet — buyer responds as a plain string or via Google Sheet integration

Once the response type is selected, fill in the mapping fields for both Ping and Post responses:

• Success Ping/Post Response — enter the success keyword the buyer returns when accepting a lead — for example “Accepted”
• Ping/Post Price — map the field that returns the price offered by the buyer
• Lead ID — map the field that returns the buyer’s Lead ID
• Ping/Post Redirect URL — map the field for redirect URL if applicable
• Ping/Post Error — map the field that returns error descriptions on rejection
• Ping Bidids & Seller Name — map additional ping response fields if required
• Post Phone Number & Post Price Reject — map post-specific response fields as needed
• Buyer Full Ping/Post Response — map to capture the complete raw response from the buyer

Once all response mapping fields are configured, click Save. The system will now correctly parse the buyer’s ping and post responses based on your selected response type and field mappings.
