## How it works
In order to block credit card details to be shared on the client-side callback, you will need to contact Affirm to configure your account appropriately.
This action will return the Affirm virtual card details associated with the `
checkout_token` that was returned by your [client-side integration](🔗). You need to request the card details via this [endpoint](🔗).
## Step 1: Retrieve the `
checkout_token` on the Client-side
## Step 2: Retrieve the full [card details](🔗) via your server
