This question is already posted here in Salesforce Stackexchange (https://salesforce.stackexchange.com/questions/268188/is-it-possible-to-retrieve-a-signed-pdf-from-docusign-and-then-put-it-in-the-not/268196#268196), I just wanna ask more about this.
We have connected the DocuSign to Salesforce using DocuSign Connect. Our problem is that we have a little knowledge on retrieving the API calls of DocuSign to Salesforce in order to get the document status and envelop. Do you have any tips and step by step process for implementing this. A use case is that we will send a document to the recipient using an API call to the DocuSign and using createAndSendEnvelope function (which we have done), and retrieve that completed document to the Salesforce to be saved in our object (which we still need to do). Thanks guys!
