DOB field is now optional

Action Required

None


Overview

The dob field has been made optional in our Create External Bank Account endpoint, to remove friction for customers who cannot easily obtain the date of birth of the individual on the account.

As a best practice, customer who do maintain this information should still continue to send the field to assist with potential future transaction monitoring efforts.
