The Seller Transaction API is designed to allow you to include transactional information where needed to suit your implementation. For example, you might choose the send the buyer's details in a Calculate Tax request or you may decide to send it in a Store Transaction request.

To facilitate this, the same structure is used for the JSON that is attached to all requests. Fields like currency_code are used to represent information like the currency. A full list of the available fields is provided in the Fields Reference section

Some fields are generated by the API so these are known as response-only fields.

You can include information at transaction and transaction line-item level. See Transaction Details
