Card Provider Server API

This page is the OpenAPI reference for the Card Provider Server (version 1.0). Ledger Backend calls these endpoints when a user buys crypto with a debit or credit card inside Ledger Wallet. Implement them on your backend as described in the sell-card backend and fund-card backend guides.

The specification below is the source of truth for paths, request bodies, and responses. Those backend guides document /sell for the signed fund payload and the /transaction/{sellId}/status webhook.
