We send Docusign documents from Salesforce Opportunities.  Currently when the main signatory has completed and signed their section of the document, we aren't notified if any other party has signed until all parties have signed.  We need to be notified if any of the parties have signed.  Is there a way to configure this? We'd like to be proactively informed when one of a number of parties have undertaken their individual part.  We have been advised to "setup a custom webhook with the trigger event -> recipient event -> recipient signed/completed". I am fairly new to developing and I do not understand how to configure this with the salesforce url endpoint?  Can anybody assist?
