The Jay Product Data API of the Media Jay application provides the capability to add full or update volatile (stock count, prices, etc.) product data.
To access the endpoints you require a X-API-Key in the header. Partners, please contact Transfermedia support@transfermedia.de to retrieve one.
To use a specific implementation version of this API place it to the request header X-API-Version. If the header is missed the latest implementation version 2025-07-09 is used. The response header X-API-Version returns the implementation version the request was processed with.
For further details please visit the documentation or contact Transfermedia support@transfermedia.de.
