Settings reference

Currently there are three settings the marketplace admin can change:

• global_product_catalog - toggle whether sellers can only add inventory to admin-managed global products,
• require_product_approval - decide whether seller-added products require admin approval before becoming ready to list,
• product_request_enabled - allow sellers to propose new products for inclusion in the catalog.

All settings are false by default.

​

Example Scenarios

1. Global Catalog ON, Require Admin Approval ON, Sellers Can Request Products ON:
   • Sellers can list inventory for global products.
   • Sellers can request new global/unique products.
   • All inventory and product additions require admin approval.
2. Global Catalog OFF, Require Admin Approval OFF:
   • Sellers freely add products without needing admin approval.
   • Admin does not need to manage requests or approve listings.
3. Hybrid Mode (Global Catalog ON, Sellers Can Request Products OFF):
   • Sellers can list inventory for global products.
   • Sellers cannot request new global/unique products.

Verification middleware

The middleware checkConfigurationRule is used to restrict route availability according to the setting value, and can be found in apps/backend/src/shared/infra/http/middlewares/check-configuration-rule.ts. It takes two arguments, rule_type and expected_value. Advanced users can use it to modify the default Mercur behaviour.
