Check - ZenPayments

For 3DS v1.0 this will return the status for the specific id.

For 3DS v2.2 if the additional challenge is needed this will return a new iframe along with the status for the specific id.

Always initiate Check for a specific id to verify the status before proceeding to an Auth or Sale. Once a status changes from the initial Pending it will never change again. The acceptable statuses for proceeding to an Auth or Sale are Success, Attempted, and Not Enrolled.

When the request is made it uses the long polling technique that keeps the request open for up to 15 seconds. During that time if a response hasn't been returned, it is strongly advised to not repeatedly poll until then. To prevent from an excess amount of polling, a polling rate limit has been put in place.

Below are the possible status values:

Code	Description	Liability Shift
Y	Authentication Successful by issuer	Yes
A	Network stepped in for the authentication because the issuer was not participating	Yes
