This operation retrieves the PAN of a card for a given client and card ID. TOQIO will send a card ID and a temporal encryption key to the integrator and the integrator will send back this body encrypted as a response. This is critical and MUST be sent encrypted as otherwise it won't be PCI compliant. You, as an integrator, MUST be PCI compliant as well.
