What are the GTIN and MPN codes?

A GTIN is an international product identifier. The module reads the EAN-13/JAN and UPC fields according to available data and the priority selected in feed options. Use the codes actually assigned to the product; do not invent them.

An MPN is the manufacturer’s part number. It is not necessarily your internal reference or your supplier’s reference. On PrestaShop versions supported by the module, fill in the product or combination MPN field; the module uses the product MPN when the combination has none.

In Feed management > Product exclusion rules > General exclusion, you can choose to exclude products missing the relevant codes. These are exclusion choices; they do not mean that TikTok always requires both GTIN and MPN.

After changing settings, regenerate the feed and check exclusion causes. Definitions and accepted fields appear in the official TikTok product parameters.

TikTok accepting ISBNs as GTINs does not mean that the module automatically reads PrestaShop’s native ISBN field: check the EAN-13 and UPC codes actually exported.
