and I want to use these fields in the email templates. I can see that there is $custom1 and $custom2, but neither of these seem to work. There also seems to be 4 custom field options…so where is $custom3 and $custom4? Are these variables for something else?
How can I use my custom fields in email templates?
In the next release you can use $payment.custom1,2,3,4 on the invoice. Just to note, if there are multiple payments on the one invoice, only the first payment custom value will appear.
