According to DocuSign documentation, we have to use "Modify or Correct and Resend Recipient Information" method in order to resend an envelope. However, this method is also expecting a collection of recipients.
Is there a way to simply resend the envelope to the current recipients?
I had originally thought about something like this:
string requestUrl = string.Format("https://{0}/restapi/v2/accounts/{1}/envelopes/{2}?resend_envelope=true", Properties.Settings.Default.Domain, Properties.Settings.Default.AccountNumber, envelopeId);
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(requestUrl);
request.Method = "PUT";
request.Headers["Authorization"] = string.Format("bearer {0}", Properties.Settings.Default.AccessToken);
