Value-added transactions let you append extra charges — like gratuities or service fees — to a base payment. Use these features to streamline tipping, cover incidentals, or support custom billing scenarios without creating separate follow-up charges.

Tips

Enable customers to add a gratuity or service fee alongside their payment. You can handle tips in two main ways:

Implementation options

Adjust a Sale
Once a sale has been made, send an adjustment request before batch closure to update the sale amount to include the tip.
Authorization adjustment
After the initial authorization, send an adjustment request before capture to update the authorized amount to include the tip.
Over-capture
When capturing, specify an amount higher than the original authorization (within scheme limits) so the tip is included in a single capture call.
