If you are looking to implement Wayfair API as a connection within your Electronic Data Interchange network, this article will provide you with an understanding of the requirements, preliminary and next steps, as well as commonly used transaction types.

Wayfair API utilizes the following IDs for identification purposes. This ID will be sent in the header level of the XML data. This allows Transaction Manager to be able to identify the Sender and Receiver of any sent/received XML transaction.
​

The table, below, lists the most common IDs used by Wayfair API.

In order to integrate the marketplace connection, the API Keys will need to be generated by following these steps:

Your assigned Implementation Specialist will coordinate with your team to ensure that we connect your Foundry to your Wayfair marketplace site, in order to receive orders and send outbound transactions within Foundry to update your marketplace order status (as applicable).
