DocuSign for Salesforce Integration Pt 2: Automatically generate Documents via Apex with DocuSign 

So why exactly this doc is not listed officialy in the website, i mean if you go from navigation menu > all apis ...notice this is not listed anywhere

I'm not sure if you are replying to comments here. I am having an issue with this. Specifically, in the following line "jsGen.writeStringField('OpportunityName', oppRec.Name);" you are using OpportunityName instead of "Name". When I try and use "Name" in the key value, then the whole thing breaks is there a reason for that? Also a lot of things seem to break if I start increasing the depth of the JSON. Is there something that prevents that on Docusign's end? Are there other sample JSON that I can reference. That might clear up some of my questions Thanks
