- Why is the install button for my app not clickable?
This occurs when your app is requesting access to API scopes that are gated to higher plans than the given site is on. Some features and as a result the associated API endpoints are only available on higher Thinkific plans. If the site installing the app is not on a sufficient plan they can not install the app.
For example: A site is on the Free Plan and your app requests the Groups API (Start/Pro+Growth or higher) scope the users will not be able to install the app.
If you find that this is occurring during testing for your app, we recommend using your Sandbox instance which will not be restricted in terms on API endpoint access.
