# Bulk mapping of materials/products to Avalara T/S pairs

**Element type: Suggested**

**Endpoints/models used:** N/A

AFC provides a number of available transaction type/service type (T/S) pairs. Your integration should allow users to map their own individual materials and products in bulk to Avalara type/service pairs. This task is handled through your environment backend and not directly via an AFC API call.
