You need to ensure that app developers have the necessary permission to submit apps for deployment. Which permission level should you grant to the SharePoint_App_Dev group?

App Manager permission in Central Administration is an administrative role scoped to managing app licenses and purchases, not for granting developers the ability to submit app packages to the catalog.

The App Store site is the SharePoint App Catalog where developers submit apps for organizational deployment, and Full Control is required to upload app packages, manage catalog library settings, and complete the submission workflow. Contribute alone is insufficient because certain catalog operations - such as managing content type settings and approval metadata - require elevated permissions beyond item-level contribution.

Contribute permission allows adding list items but does not provide the library management rights needed to fully publish and manage app packages in the App Catalog submission process.

Farm Administrator permission grants unrestricted access to the entire farm infrastructure, far exceeding what is needed for app submission and violating the principle of least privilege.

Full Control to the Central Administration site grants access to farm management functions but does not extend permissions to the App Store site where app submissions actually take place.
