You must work with Pismo to pre-register a script and get its script ID. For information on generating a PINBlock and key ID, refer to the [PIN/PINBlock tutorial](doc:pinpinblock-tutorial) guide. For more information, refer to the [Card scripts](doc:card-scripts) guide. **Note:** This is a PCI endpoint, use the https://gw-pci.pismolabs.io/ environment. # OpenAPI definition ```json { "openapi": "3.1.0", "info": { "title": "Card issuing - Cards", "version": "1.4.6", "description": "Card endpoints API", "contact": { "name": "API Support", "url": "https://developers.pismo.io/support/" }, "license": { "name": "Copyright Pismo" } }, "servers": [ { "url": "https://sandbox.pismolabs.io", "description": "Sandbox API server for testing." }, { "url": "https://gw-pci.pismolabs.io", "description": "Sandbox PCI API server for testing." } ], "security": [ { "BearerAuth": [] } ], "tags": [ { "name": "PCI", "description": "Card PCI/sensitive information endpoints" } ], "components": { "parameters": { "cardId": { "in": "path", "name": "cardId", "schema": { "type": "string" }, "description": "Pismo card ID", "example": "12345", "required": true }, "x-AccountIdHeader": { "in": "header", "name": "x-account-id", "schema": { "type": "string" }, "description": "Account ID", "required": true, "example": "8675309" } }, "schemas": { "AccountID": { "type": "integer", "description": "Pismo account ID", "example": 7654776 }, "AppendUpdatePinIssuerScriptBody": { "type": "object", "description": "Object used to append issuer script to update card PIN", "required": [ "script_id" ], "properties": { "script_id": { "type": "string", "description": "Issuer script ID.
