Update fees

In case you need to update the fee after you've submitted it to Rootline, you can do so by using the PATCH /payments/{id} method. Some scenarios that can be solved:

a fee needs to be lowered or removed because of a full or partial refund;
a fee needs to be added because an extra service was used.

Important

There is a time limit to updating the payment. You can do so by updating the payment up to 7 hours after the payment is authorized.

PATCH the payment to update the fee(s)

Provide the split payment_id with the fees array, and:

add a fee object to charge a(nother) fee;
provide the fee_id of a fee that you want to increase, decrease or set to € 0.00.
