A semi-automated process for app approval is available in the Developer Console.
Navigate to the Authorization tab for your application in the Developer console.
Submitting the application for approval will send an email to your enterprise's Admin to approve the application. More information on this process is available in our support article on app authorization.
If the above process is not an option, the following steps provide instructions on how to manually approve the application.
As the developer, navigate to the Configuration tab for your application in the Developer Console. Scroll down to the OAuth 2.0 Credentials section and copy the Client ID value to provide to your Box Admin.
As a Box Admin, navigate to the Admin Console and select the Apps tab (1) from the left navigation panel. Then, click the Custom Apps tab (2) at the top of your screen. On this screen, you will see a + button in the top right corner to add a new app authorization.
In the popup that appears, enter the client ID for the application that the developer collected from the Configuration tab of the Developer Console.
When the application's scopes or access level change the application needs to be re-authorized. Repeat the process above and request a new Access Token for the new changes to take effect.
In the same section where the application was initially authorized, an Admin can re-authorize the application by clicking on the ellipses to the right of the application name and selecting "Reauthorize App".
