# Partner review

Learn how to contact Avalara for integration review and understand key features of RESTv2 for partners.

If you're a technology partner refactoring your integration, contact Partner Launch at [DG-PartnerLaunch@avalara.com](mailto:DG-PartnerLaunch@avalara.com) when you're ready for Avalara to review your integration.

* RESTv2 users have access to a TransactionBuilder SDK, which isn't available in SOAP.

* In RESTv2, multitax is enabled by default for users who have the appropriate entitlements and who pass the appropriate parameters for each specific tax type. You can retrieve a list of all supported tax types by running the [ListTaxTypeGroups](https://developer.avalara.com/api-reference/avatax/rest/v2/methods/Definitions/ListTaxTypeGroups/) RESTv2 API. If you have questions about implementing a particular tax type, contact Partner Launch at [DG-PartnerLaunch@avalara.com](mailto:DG-PartnerLaunch@avalara.com).
