I’m building a contract management system using Node.js that integrates with DocuSign. When a contract is created from the frontend, an email is sent to the customer with a document to be signed. I’ve successfully set up a trigger event using DocuSign Connect, so that once the customer signs the document, DocuSign sends a payload to a specified URL (currently pointing to a test URL from WebHook.site).

Now, I need to configure my Node.js application to receive this webhook payload, allowing me to process it and perform certain database updates after a successful customer signature. What’s the best way to achieve this integration?
