I reply you by email

Can you put this instruction in the Authentication settings description? Alternatively, I’d like to discuss with you the option of setting a Secret Parameter so that Mashape developers can immediately start using your API without having to register to a separate page (which in our opinion affects adoption of APIs). You can check the details here - http://blog.mashape.com/post/50590118603/new-feature-secret-parameter-and-headers . Please email me at chris@mashape.com if you have questions. Thanks!
