App Not Setup

If you see the following error message when attempting to sign in using Facebook, your app is still in development mode and you need to set it to public mode:

App Note Setup: This app is still in development mode, and you don't have access to it. Switch to a registered
test user or ask an app admin for permissions.

For instructions on setting your app to public mode, see step 11 at Configuring Sign-In using Facebook.

Does my App require approval by Facebook?

Some permissions and features of the Facebook API require review by the Facebook team. The WHMCS Sign-In Integrations use the following permissions:

• public_profile
• email

These permissions do not require approval for use and you can continue to use your app without submitting it for approval.
