- Adds a clear validation checkpoint
- Reports when no IBAN is available

- 5Test with one real event containing an IBAN.
Questions about this workflow
Does Mailchimp always provide an IBAN?
No. The workflow only validates an IBAN when one is present in the event context or supplied by the user.
Does validation authorize a payment?
No. It checks the IBAN structure through the Api labz validation action.
