# API Configuration source: https://developer.mastercard.com/mastercard-processing-core/documentation/api-basics-section/configuration/index.md The Mastercard Processing API enables a customized configuration for each issuer to align with specific requirements. Configuration includes, among others, definitions of special fields, available characters, and dictionaries. Part of the API configuration is also a list of `operationId` enabled for each issuer. The list depends on the product that the issuer wants to implement. The following `operationIds` are available for credit, debit, and prepaid products. | Section | Use case | OperationId | Credit card | Debit card | Prepaid Card | |---------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------|-------------|------------|--------------| | Card lifecycle management | [Order a Virtual Card](https://developer.mastercard.com/mastercard-processing-core/documentation/use-cases/card-lifecycle/order-a-virtual-card/index.md) | createClient | + | + | + | | | | createAccountContract | + | + | + | | | | createCardContract | + | + | + | | | [Order a Physical Card through Mastercard Processing Personalization Bureau](https://developer.mastercard.com/mastercard-processing-core/documentation/use-cases/card-lifecycle/order-through-mc-pb/index.md) | reissueCard | + | + | + | | | [Order a Physical Card through Issuer's Personalization Bureau](https://developer.mastercard.com/mastercard-processing-core/documentation/use-cases/card-lifecycle/order-through-is-pb/index.md) | reissueCard | + | + | + | | | [Replace a Card with New Virtual and Physical Cards](https://developer.mastercard.com/mastercard-processing-core/documentation/use-cases/card-lifecycle/replace-vc-with-pc/index.md) | changeCardContractStatus | + | + | + | | | | reissueCard | + | + | + | | | [Replace a Physical Card](https://developer.mastercard.com/mastercard-processing-core/documentation/use-cases/card-lifecycle/replace-pc/index.md) | changeCardContractStatus | + | + | + | | | | reissueCard | + | + | + | | | [Renew a Card with New Virtual and Physical Cards](https://developer.mastercard.com/mastercard-processing-core/documentation/use-cases/card-lifecycle/renew-with-vc-pc/index.md) | reissueCard | + | + | + | | | [Renew a Physical Card](https://developer.mastercard.com/mastercard-processing-core/documentation/use-cases/card-lifecycle/renew-pc/index.md) | reissueCard | + | + | + | | | [Activate a Card](https://developer.mastercard.com/mastercard-processing-core/documentation/use-cases/card-lifecycle/activate-a-card/index.md) | activateCard | + | + | + | | | [Display Card Details to the Cardholder](https://developer.mastercard.com/mastercard-processing-core/documentation/use-cases/card-lifecycle/disp-card-det-to-crdholder/index.md) | getCardContract | + | + | + | | | | getCVC | + | + | + | | | [Set or update authentication method](https://developer.mastercard.com/mastercard-processing-core/documentation/use-cases/card-lifecycle/set-update-auth-method/index.md) | setAuthenticationMethod | + | + | + | | | [Verify Card details (PAN, expiry date, CVC2)](https://developer.mastercard.com/mastercard-processing-core/documentation/use-cases/card-lifecycle/verify-card-details/index.md) | verifyCardDetails | -

Note: If you try to execute the `operationId` that is disabled in your API configuration, you will receive a dedicated error. For more information about error messages, see [Error Codes](https://developer.mastercard.com/mastercard-processing-core/documentation/code-and-formats/index.md). Tip: As an issuer, you determine the scope of API operations to support. During onboarding, you can select the operations and business use cases you want to enable by completing the Product Parametrization Workbook (PPW), specifically the API Operations worksheet. A minimum set of core operations is mandatory and is pre-enabled in the PPW with Value = Yes and Type = Default. These operations must be implemented by every issuer. Examples include `createClient`, `createAccountContract`, and `createCardContract`. All API operations enabled in the PPW must be implemented, tested, and formally validated during User Acceptance Testing (UAT). Successful validation of these operations is required to obtain approval and gain access to the Production environment. ## Dictionaries {#dictionaries} API uses dictionaries to: * Validate values used in requests. * Transform values between API and Card Management System (CMS) in both directions. Realizing those functionalities requires a specific configuration based on which API operation can execute validation and transformation actions. Dictionaries store the possible values of some fields used in API operations and sometimes store mappings to CMS values. All dictionaries must be configured during onboarding. API allows limiting or extending the available characters or setting a specific mask for sending the data, such as phone number or e-mail.
