Introduction to the Taxamo Assure service and the Seller Transaction API.

What is Taxamo Assure by Vertex?

You can use the Taxamo Assure by Vertex service to complete the following tasks:

  • Determine the party (seller, buyer, or Taxamo) who is liable for tax.
  • Calculate the tax rate.
  • Process refunds.
  • Generate invoices.

The service is intended for physical goods valued at €150 or below. For more information, see Taxamo Assure.

For more detailed information about how it works, see How Taxamo Assure Works.

What is the Seller Transaction API?

The service is based on the Seller Transaction API. This is a RESTful API that contains a set of endpoints for handling transactions, like sales and refunds.

The API facilitates the integration between Taxamo and your checkout processes and baskets.

The following table outlines an example of what this integration might look like. It is intended to show how your business processes can be mapped to the endpoints that you send requests to. These examples are simplified to give you a sense of how the API integration works:

Where Taxamo is liable for VAT, an invoice is generated automatically for confirmed transactions and emailed to the buyer. Where Taxamo is not liable, an invoice link is provided in the API response. For more information, see Configuring Invoices.
