The Merge URL, found in the Document Merge tab, is used to receive data route document merge data in your Documerge account. Documerge provides this URL for sending a POST request, allowing you to transmit your data by including query parameters in the URL.
In addition to sending a POST request to the URL, you can also copy the URL and open it in a browser. This will display a form with all the input fields available for that data route.
