Thanks..But that does not seem to work too... POSTED , with headers as appKey(key) - value (application key) and Content-Type - application/xml
In body - selected Form-Data and browsed the xml file and hit the URL :
Recieved error :
<h1>HTTP Status 405 - HTTP method POST is not supported by this URL</h1>
<HR size="1" noshade="noshade">
Which version of Thingworx are you using? I believe older versions doesn't support POST.
For sending plain text data we could use method=POST in query parameter as:
however for sending File, even I'm not sure.
