I have a DocuSign with multiple signature field (one primary and others secondary), I need to send a form to primary signer where there are few additional email fields which the primary signer will fill and the document needs to go to those email ids (which primary signer has provided in the form). Primary recipient has to sign first signature field and then send the same form to another recipient and he has to sign other signature field keeping the previous recipient signature and so on and I have to set the recipients programmatically in envelop. Is it possible? and how can I implement that?
