# Proper bundle handling

**Element type: Required for Voice**

**Endpoints used:** [GetProfiles](https://developer.avalara.com/api-reference/communications/v2/methods/Customization/GetProfiles/), [GetTsPairs](https://developer.avalara.com/api-reference/communications/v2/methods/Lookups/GetTsPairs/)

For partners who are achieving the Voice advanced feature, you must show that your integration correctly sends a profile ID along with customer T/S pairs to trigger a bundle.

Refer to the [Add a Bundle Group to apply separate transaction/service pairs to bundled items](https://help.avalara.com/AvaTax_for_Communications/Customer_Portal/Add_a_Bundle_Group_to_apply_separate_transaction%2F%2Fservice_pairs_to_bundled_items) Help Center article for information on how to add bundles.
