Changing a Collection Order

API Method = ChangeCollectionOrder

The change in payment slips is necessary when the data in the slip is not consistent with the billing data (values or due date).

Due Date
Principal Value
Rebate Value
Fine Date

Important:

Only issued or registered Collection Orders can be changed;
Collection Orders that are in the payment process, settled, or cancelled cannot be altered;
Changing Collection Orders works 24/7;
