If you're using DocuSign's REST API for integrating e-Signing into your application then it's possible you'll come up against the issue of duplicate fields not populating. This is when you have the same field with the same label e.g. Company Name in multiple places on the Document but you only want to send a single label, value instance to the API and have it populate in all places where the field is. When you pass the label and value like so: { label: "company_name", value: "Blogger.com" } If you have the field company_name more than once in the document then only the first field will be populated. After a lot of digging into the DocuSign documentation I discovered the solution is to append "\\*" to the label name: { label: "\\*company_name", value: "Blogger.com" } Why this isn't the default behaviour is beyond me but the solution works as expected.
