DocuSign using Chilkat dll, how do I pass templateRoles in json?

I am creating demo application which Docusing pass file and signer dynamically, for that i need to use docusign templateid and pass details, i can pass file using templateid which signer already defined in template itself, now i want to pass multiple signer as dynamically.For that need to use templateRoles.

 Dim json As New Chilkat.JsonObject
    json.UpdateString("documents[0].name", "Testing.pdf")
    json.UpdateString("documents[0].documentBase64", base64String)
    json.UpdateString("documents[0].documentId", "2")
    json.UpdateString("emailSubject", "DocuSign REST API Testing Sample")
    json.UpdateString("emailBlurb", "Create and send an envelope from a document.")
    json.UpdateString("templateId", "xxxxx-xxxxx-xxxxx-xxxx-xxxx")
    json.UpdateString("templateRoles", "{roleName: Signer 1, name: Aravind, email: [email protected], recipientId: 1}") ' Here i pass template role for signer 1, and also need to pass multiple signer.
    json.UpdateString("status", "sent")

    rest.AddHeader("X-DocuSign-Authentication", "{ ""Username"":    ""[email protected]"",  ""Password"":""DocuSign_password"",  ""IntegratorKey"":""DocuSign_Integrator_Key"" }")
     

    rest.AddHeader("Content-Type", "application/json")
    rest.AddHeader("Accept", "application/json")

    Dim sbRequestBody As New Chilkat.StringBuilder
    json.EmitSb(sbRequestBody)


    Dim sbResponseBody As New Chilkat.StringBuilder

    success = rest.FullRequestSb("POST", "/restapi/v2.1/accounts/xxxxxx/envelopes", sbRequestBody, sbResponseBody)
    Dim respStatusCode As Integer = rest.ResponseStatusCode

Here i paste code for ur reference, in that email,password,key everything i chanage,bcz it releted to security purpose. When i pass templateroles with values i get error.For above code i get following error return from api.

"errorCode":"INVALID_REQUEST_PARAMETER","message":"The request contained at least one invalid parameter. 'recipientId' not set for recipient."

Pls help me to solve this error.

Solution

Try to remove recipientId: 1 from the JSON in line 8.

But I strongly suggest you reconsider your architecture choices. You are using legacy authentication which is not very secure.

You could use the C# SDK, which is a Nuget package and works just as well with VB.NET and that would help you make these calls without using JSON and also using modern OAuth that is much more secure.
