I want to create an app. The key part of this is the authenticate and deliver specific content based on tiered permission levels. The CMS for handling and delivering the content will also be a core part of the project. Hierarchy is as below: 1. Country 2. County 3. Location 4. Village 5. Group 6. User So the user logged in should only get articles (or whatever content is there) related to the group he is a part of. Basically authentication is needed in the app. Would it be possible to create a module (and the APIs) using ProcessWire for this purpose? Is there any module available as per my requirements?
