    Hi @cookney,

    Do you have fees or coupons that have amounts of $0 on your site?

    In version 3.2.1, we added additional transaction line items for accounting. The new code includes fees and coupons but I wouldn’t expect a fee or coupon to have a $0 amount but that’s the only way you would be getting that message.

    @cookney,

    I just released a new version, 3.2.2, which prevents $0 unit amounts. Or you can just disable line items all together which prevents those validations.

    Can you explain how your site could have $0 fee or $0 coupons?

    Kind Regards,

    we have a coupon which adds a product for free to the basket if they spend ￡20+

    these 3 baskets had this however we have had baskets over ￡20 and paid by PayPal and these sent through ok..

    I. did disable line amounts so hopefully now looks like is ok.

    @cookney,

    Thanks for explaining. The new release, 3.2.2, will ensure line items with unit amounts of $0 are not added to the transaction and thus not fail Braintree’s validation.

    @cookney,

    Would you mind contacting me via our support email? I have some more questions about how you are using coupons and if you’re using the WC coupon functionality or a coupon plugin.

    Kind Regards,
