To group your vouchers together, making reporting much easier, you can create categories. Third parties also often use categories via API, so they know which category of voucher to display to customers.
To create categories, follow the steps below:
Click Vouchers, then click Manage Categories.
Click Add Category.
Enter a name and description for the category.
You can also change the order it appears in your list, and add an image.
For third parties, the category ID is the order number.
Click Add.
