Ensure that the EnvelopeDefinition object you are passing to CreateEnvelope is correctly structured. A common reason for a 500 Internal Server Error is malformed or incomplete data.

Can you share the structure of your API call?

I have attached the example I am using to create the Envelope along with the json of the envelope object I am sending.

Have you got the api log for this request? is the base url correct?

I am not sure the API log logs 500 errors, as I do not see it anywhere. Does the base url change after authentication, and if so what would that be?

Thanks

You can get API logs as this document told. clear the log and enable it. then reproduce, then download the logs. if the request can’t be find in the api log, I think the url should be not correct.

Fiddler Classic does not even show a call out when calling the CreateEnvelope, so my guess is the envelope is not valid, but i am using the example docusign provided? Any suggestions? 

could you provide the code?

Hi,

I have downloaded your envelope.json, changed the email for each recipient, and sent it via Postman and it worked correctly.

Here is the response from the API

{
    "envelopeId": "61c8897b-xxxx-xxxx-xxxx-788454b53a16",
    "uri": "/envelopes/61c8897b-xxxx-xxxx-xxxx-788454b53a16",
    "statusDateTime": "2024-09-11T06:26:44.8030000Z",
    "status": "sent"
}

If you can provide your C# code as other have suggested, this might help assist.

I would suggest you utilize Docusign's API Request Log to find the exact error you've got from the Docusign server. More information about how you can capture the log is here: https://support.docusign.com/en/guides/ndse-user-guide-api-request-logging

Thanks everyone. It would seem I did not have the correct url.

for authentication i was using account-d.docusign.com but when posting to CreateEnvelope I was not putting the /restapi at the end.

that's good news, I,also meet this,issue before.
