I have been beating my head against the wall trying to figure out some things with the PLM 360 API and have been continually getting "500 - Internal Server Error" messages. I think this is primarily due to me not formatting the body of my request correctly, but at this point, the best I can do is blindly guess at what correction needs to be made (the help guide is fairly useful, but something like that can only go so far when it's not customized for what you're trying to use it for). Therefore, I would really love to have access to an API console similar to what 500px has set up for their API (https://apigee.com/vova/embed/console/api500px). This would be an immense help in figuring out how the API requests should be made.
