# Test transactions

The examples in this section are based on the Nexus settings that are described in the [Create and activate a company](https://developer.avalara.com/vat-erp/configure-your-avatax-account/create-and-activate-a-company-vat) topic. If you set up your test company the same way, then you'll see the same responses when you run these examples.

These examples are broken out into Core requirements, Input VAT, and Triangulation.

* All integrations must review and run the Core requirements examples.

* If you're also attempting to get certified in the Input VAT advanced feature, then review and run the Input VAT examples.

* If you're also attempting to get certified in the Triangulation advanced feature, then review and run the Triangulation examples.
