Mapping categories guarantees that the VTEX category tree has a correct association with the marketplace’s category tree.
To perform this association, VTEX made VTEX Mapper available. It is a tool integrated to the VTEX platform that allows the user to relate categories created in VTEX to categories from the marketplace.
This endpoint allows connectors to send the marketplace's category tree mapped in the integration.
Connectors should send the payload compacted in .gzip format.
