# Simulate step-up retrieve methods

**POST** `/simulate/issuing/cards/tokens/{card_token_id}/step-up/methods`

Simulate Visa's retrieve step-up methods callback for a sandbox card token. Returns the SMS and email methods available
from the cardholder's contact info, or an empty list when none is on file, and records them on the token so a later
send passcode call can resolve the selected method.

### Path Parameters

- `card_token_id` `string` _(required)_ — Unique identifier for the card token.
