Verify a payment card.

Use this to perform card verification for a payment card.

### Example
```ruby
# load the gem
require 'openapi_client'

api_instance = OpenapiClient::CardVerificationApi.new
content_type = 'application/json' # String | content type
client_request_id = 'client_request_id_example' # String | A client-generated ID for request tracking and signature creation, unique per request.  This is also used for idempotency control. We recommend 128-bit UUID format.
api_key = 'api_key_example' # String | 
timestamp = 56 # Integer | Epoch timestamp in milliseconds in the request from a client system. Used for Message Signature generation and time limit (5 mins).
card_verification_request = OpenapiClient::CardVerificationRequest.new # CardVerificationRequest | 
opts = {
  message_signature: 'message_signature_example', # String | Used to ensure the request has not been tampered with during transmission. The Message-Signature is the Base64 encoded HMAC hash (SHA256  algorithm with the API Secret as the key.) For more information, refer to the supporting documentation on the Developer Portal.
  region: 'region_example' # String | The region where client wants to process the transaction
}

begin
  #Verify a payment card.
