dousign api soap composite templates - docusignapi

Question

See Updated XML. It has changed the output but still not quite right. Now it uploads doc1 and applies template correctly and inserts templates 2 & 3 in the correct location, however doc2 & doc3 are not there. Just the document that was used to create the template.

"Content-Disposition: file; filename=\"" + fileName + "\";documentId=2; compositeTemplateId=2\r\n\r\n";
"Content-Disposition: file; filename=\"" + fileName + "\";documentId=3; compositeTemplateId=3\r\n\r\n";

This is REST using XML for payload rather than JSON. In the DocuSign REST API, using compositeTemplates with multi-part form contribution of documents gets a little tricky when applying server templates to those documents. The server template's tabs are assigned to documentId=1. Therefore, you must do the same. To properly map the document contributed by each composite to the correct document contributed per multi-part form, you must use compositeTemplateId.
For each element, add . Make the first one "1", second "2", third "3". Then, for each form where you attach the documents, add the "compositeTemplateId=n" (where n= 1, 2, or 3) to that form's Content-Disposition.
e.g.:
--BOUNDARY
Content-Disposition: file; documentid=1; name="Option2"; filename="Option2.pdf"; compositeTemplateId=2
Content-Type: application/pdf
