Usually this issue occurs when you have just created your Apple Developer account. It should start working roughly 2 days after paying the Apple Developer account fee. Apple will also send you an e-mail with the subject "Welcome to App Store Connect".

So please wait 2 days and then try following this guide again. If the issue still persists, you can also try clearing your browser's cache and cookies. If that doesn't help either, please contact Apple's support.

Requesting access to the API

Click "Request Access" to get access to the App Store Connect API.

Click "Request Access".

Tick the checkbox to agree to the terms and click "Submit".

Information about the API terms

Unfortunately the terms for the App Store Connect API are a bit short and vague. They say you may only use the API for internal purposes. We think that your use of webtoapp.design to create and upload your app counts as internal purpose. There's lots of other services where you access the App Store Connect API in a similar way for similar purposes, which supports this point of view.

Tick the checkbox to agree to the terms.

You might have to wait a bit until your request gets approved. You will get an e-mail then. In many cases the approval is instant though.
