How to get a QR code?

I am not a web developer but am creating a simple site to get a QR code from here

I want to test the API in postman, so I set the POST request to be this:

and then set the body to:


as raw (application/json)

But I get a response which says " Sorry, the page you are looking for could not be found."

What am I doing wrong?

Here’s a screenshot


Do you have a subscription with Mashape? I believe you would have to supply authorization for Mashape in order to have access to the QR Code API. From your screenshot it doesn’t look like you are setting anything for authorization.
