I've added CARD_STREET_ADDRESS to the Iframe integration sample in the clover docs.
The CARD_STREET_ADDRESS seems to be mandatory since if my user doesnt type in a value, the createToken method returns a null result, but there doesnt seem to be any validation or error message
if the merchant has AVS fraud rules enabled and backend says that the street address provided is wrong the charge will fail
Yes. In this document: https://docs.clover.com/docs/using-the-clover-hosted-iframe
the call to clover.createToken() returns a null result if the address doesnt meet the requirements.
I was expecting something similar to the validation of the card number, that is to say, a result object with an errors object with "CARD_NUMBER" set to a string representing the reason for the validation failure.
