integration of Appian workflow with DocuSign

Thanks Tyler, It did fix the issue related to expression but I guess removing[] another issue. When I ran the process, It got completed but got following error on output:

{ "errorCode": "INVALID_REQUEST_BODY", "message": "The request body is missing or improperly formatted. Cannot deserialize the current JSON object (e.g. {\\"name\\":\\"value\\"}) into type 'API_REST.Models.v2.document[]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.\\r\
To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List<T>) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.\\r\
Path 'documents.documentId', line 1, position 98."}

Could you paste your latest expression :-)?

=a!toJson({status: "sent",emailSubject: "Request a signature via email example",documents:{documentId: "1",name: "Test_sign_PDF_Template.pdf",documentBase64: "#31754#"},recipients: {signers: {name: "Rishu Bansal",email: "r.rishubansal@gmail.com",recipientId: "1",tabs: {signHereTabs: {xPosition: "25",yPosition: "50",documentId: "1",pageNumber: "3"}}}}})

Could you try this? I just wrapped the documents and signers fields in brackets to make them an Appian list.

a!toJson(
{
status: "sent",
emailSubject: "Request a signature via email example",
documents: {
{
documentId: "1",
name: "Test_sign_PDF_Template.pdf",
documentBase64: "#31754#"
}
},
recipients: {
{
signers: {
{
name: "Rishu Bansal",
email: "r.rishubansal@gmail.com",
recipientId: "1",
tabs: {
signHereTabs: {
xPosition: "25",
yPosition: "50",
documentId: "1",
pageNumber: "3"
}
}
}
}
}
}
}
)

Sure

Actually, try this one. Did the same with signers and tabs:

a!toJson(
{
status: "sent",
emailSubject: "Request a signature via email example",
documents: {
{
documentId: "1",
name: "Test_sign_PDF_Template.pdf",
documentBase64: "#31754#"
}
},
recipients: {
{
signers: {
{
name: "Rishu Bansal",
email: "r.rishubansal@gmail.com",
recipientId: "1",
tabs: {
{
signHereTabs: {
{
xPosition: "25",
yPosition: "50",
documentId: "1",
pageNumber: "3"
}
}
}
}
}
}
}
}
}
)

Sorry, Still getting error:

{ "errorCode": "INVALID_REQUEST_BODY", "message": "The request body is missing or improperly formatted. Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'API_REST.Models.v2.recipients' because the type requires a JSON object (e.g. {\\"name\\":\\"value\\"}) to deserialize correctly.\\r\
To fix this error either change the JSON to a JSON object (e.g. {\\"name\\":\\"value\\"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.\\r\
Path 'recipients', line 1, position 1718938."}

Sorry, still above mentioned issue

Hmm, okay I'm not sure why that's not working. If you can't figure that out, another thing to try would be using a CDT. On my project we had a CDT for envelope, which had a nested CDT of recipients, which had a nested CDT of signers, etc. So you could try creating a CDT matching the structure and then just to toJson on your CDT.

Otherwise, not sure what that error means.

okay, Thank you so much for all your help Tyler.
