When creating a transaction, a surcharge fee can be added to the request in amountDetails. See the main surcharge guide or any of the API links above for more details. You must contact Moov to enable surcharging and start the registration process.

Note that API v2026.07.00 is considered in-development until the final release in July.

Tax amount

The taxAmount field is being deprecated in Moov API v2026.07.00 onwards. Taxes can now be added to amountDetails. This affects general transfers, payment links, and invoices.
