If you're experiencing a Facebook Catalog permission error, there are several steps you can take to try and resolve the issue:
Check your Business Manager permissions: Make sure you have the necessary permissions in Business Manager to access and manage catalogs. You must have either the "Catalog Admin" or "Catalog Manager" role to view, create, or modify catalogs.
Check your catalog permissions: If you have the necessary Business Manager permissions, check the permissions for the specific catalog you're trying to access. Make sure you have the appropriate permissions to view, add, or modify products in the catalog.
Verify your domain ownership: If you're trying to set up a new catalog or add a new domain, you may need to verify domain ownership to ensure that you have the necessary permissions to add products or make changes to the catalog.
Check for account or catalog restrictions: Facebook may restrict access to catalogs for certain types of accounts or businesses. Check to see if your account or business is affected by any of these restrictions.
Contact Facebook support: If you're still experiencing issues with your catalog permissions, you can contact Facebook support for assistance. Provide as much detail as possible about the issue you're experiencing and any steps you've already taken to try and resolve it.
By following these steps, you can troubleshoot and resolve Facebook Catalog permission errors, allowing you to effectively manage your product catalogs and run dynamic product ad campaigns.
