In the same way that you may download a product template, containing a list of all your listings within our system, you may retrieve and upload this file programmatically. The file format you must upload is comma-separated ('CSV’). The format of the file you may retrieve is also comma-separated. When uploading a repricer file, only those listings contained within the file will be updated within our system. Also, the smaller the file size, the faster the desired action occurs.
