Hello. I tried to send "docx", "rtf" and "txt" files using sendDocument API method but had errors every time. Also there was a try by your soft to convert "rtf" to PDF but with no success and with PDF source code in the final document(the one that a recipient got ). I just wanted to ask if it is possible to send you specified file formats using your API sendDocument method or it is possible only through your website? Thanks )
Yes, EchoSign supports most of the document file formats via API. If your API call is not going through you must be defining some API parameters wrong.
Support will need to check your account info to look into the API log and troubleshoot it. You will need to contact the support team to troubleshoot.
