API Response for the send_document call for the Echosign.
HTTPI POST request to secure.echosign.com (net_http) SOAP response (status 500) soap:Server Invalid API Key:
API key is not the invalid one as this is working fine for the "getUsersInAccount" API call.
Did anyone faced this issue and know what could be the probable solution for this.
It's an data error. That means APi key which u are passing in request is not valid for particular operation. If you want to find the exact error, which is being return by server about that data, run this wsdl in soapui.
