docusignapi - How to map each DocuSign request to envelopeId -

i trying implement docusign api app send documents our clients e-signature. in application, need send 1 document each client e-signature. example, agreement doc user sign , agree our terms , conditions.

so sending same document each client , assume receiving unique envelopeid each individual request.

so how keep track of envelopeid associated user?

can send custom tag in request , receive in response track it?

most docusign users build functional integration.

integration such salesforce, crm , other products integrate docusign system track either through envelope custom field (with internal application record information) or document envelopeid responses , store them in application.

either way work out same, it's on how want integration work.
