The `Card` resource never carries a reveal URL. When `cardCapabilities.supportsPanReveal` is false, this endpoint cannot reveal the card. Use the card issuer's challenge-based hosted reveal flow instead. Request the reveal right before rendering the iframe and render the returned `panEmbedUrl` immediately; it expires at `expiresAt` (within minutes). Never store, cache, or log the URL — it is a bearer secret for the full card details. The card data renders inside the processor's iframe and never crosses Grid's or your servers. Set `cardConfigs.panRevealCssUrl` on your platform config to style the iframe with your own stylesheet, or send `cssUrl` in the body to override it for one reveal. Every reveal is audit-logged with the requesting actor. ## OpenAPI ````yaml https://app.stainless.com/api/spec/documented/grid/openapi.documented.yml post /cards/{id}/reveal openapi: 3.1.0 info: title: Grid API description: > API for managing global payments on the open Money Grid.
