Read a card verification
Reads the verification’s state without changing it, including whether it has expired and the saved method once approved. This is how a member API client follows the issuer challenge: poll it after showing the challenge, until state leaves pending (approved once the issuer accepted it, otherwise denied, timed_out or cancelled), then confirm. No event stream is offered to member API clients. A POST, as the catalogue specifies. The verification is bound to the member that started it: another member’s verification, or an unknown id, returns 404. Responses carry Cache-Control: no-store. Requires a writable member credential.

}Authorizations
A member credential in the Authorization: Bearer header: a member
session JWT, a portal JWT whose login is linked to a membership in
that company, or an opaque member token. The credential alone
identifies the member and company.
Body
application/json
The verification id returned by POST /payment-methods when verification was required. It names the verification for the authenticated member only and grants nothing on its own.
Minimum string length:
