You can add products to your account either individually or in bulk.
Adding a single product
Go to the Catalogue tab and click on the “Add product” button
Complete the fields for GTIN and product name (adding a group is optional)
The GTIN field does error validation so that you cannot upload an invalid GTIN or one that your company does not own
(Optional) For the group field you can either select an existing group you have already created by clicking inside the Group box, or you can type in a new one to create along with the product
Click on the "OK" button
Note that if you have created any product attributes, these fields will also show here.
