How to update billing information for a Flex Token?
Currently, I'm working with 2 apps where user can generate a payment token associated with their account. 1 uses the Secure Acceptance Hosted Checkout and the other uses Flex Microform. 1 possible case involves the user's card being captured via the Microform and then later updated via the Hosted Checkout.
The docs mention being able to replace the billing info associated with the Flex token, but it's unclear the mechanism available. I'm aware that the Hosted Checkout supports updating this info, but it's preferred to make the update without prompting the user via the Hosted Checkout so the user never needs to see the default address or require putting in their address twice. Is there an endpoint that can be uses to achieve this?
