All API requests return error 403

Any uses of the API return error 403, even using the devoloper preview for basic requests like getting classes. The same requests and code worked a few days ago. Sorry if the wording is weird, I’m still pretty new to this kind of stuff. Below I’ll past the error.

“status”: 403,
“error”: “No Application Name associated with this API key. A name must be specified so that your application can be identified.”

You need to go to your user Settings and specify a name for your application so that it can be identified.

I knew it would end up being a stupid question. Thanks for the help.
