Is there a way that I can provide any custom document metadata when adding documents to my DocuSign envelopes when using the REST API?
DocuSign appear to enforce the use of a positive integer for the DocumentId's we provide in the envelope. Whilst we are indeed using a positive integer, sometimes, there is some additional info that we need to supply, which we would like to come back in the DocuSign webhook events for specific documents.
I've had a look at the Document object but can't see anything obvious that I could use. An example would be simply providing a true/false along with a specific document, which I can inspect when I receive the DS webhook events.
At the moment, the only workaround I can think of is to add an Envelope Custom Field which contains any of my DocumentId's where 'true' is applicable, which feels like a bit of a shoddy solution, and I don't know if there's a character limit in those Envelope Custom Fields, which could break such a workaround.
