The IBAN of your customers can be updated in your eCurring account or through the API(update customer).
If you want to do it through your eCurring account, follow these steps:
- Go to 'Customers' in the menu
- Search for the customer and click on it
- Scroll down until you reach 'Mandate details' and click 'Revoke'
- After you've revoked the old mandate, you can click 'Activate'.
- Fill out the new bank account holder and IBAN
- If applicable, tick the box for 'Assign the mandate to all active subscriptions of this customer'
- Click on 'Submit'
All future SEPA direct debit transactions will now be charged from the new IBAN.
