Starting from April 8th, the fields: cards.issuer, cards.payment_method, and cards.security_code will no longer be returned in queries made to search for customers, unless the parameters: email or customer_id are included. If you need to access these fields, it will be necessary to consume the GET endpoint: /v1/customers/{customer_id}/cards.

We included the new SDK Go language in some integration sections of the documentation for Checkout API, Checkout Pro , and Webhooks notifications.
