Brand

The "brand_id" attribute (optional) is available in Lengow at the attribute mapping step. Enter either the brand name or the TikTok brand ID. 

• If the brand exists on TikTok Shop, Lengow checks if the seller is authorized to use it.
• If the brand doesn’t exist, Lengow creates it using the provided name. The seller must then request authorization in the TikTok Seller Center.

If you provide a brand, your product can only be listed once this brand is authorized.

To get a brand authorization, log in to your TikTok Seller account and submit the necessary documents. Once approved, the brand can be linked to your products.
