# Release History source: https://developer.mastercard.com/mastercard-checkout-solutions/documentation/release-history/index.md This section details all updates to Mastercard Checkout Solutions, with dates and a summary of what has changed. | Date | Description | |--------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | June 2, 2026 | The [authenticate()](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/sdk-reference/authenticate/authenticate_clicktopay/index.md) function for Click to Pay now supports Passkey verification at the login stage of the user workflow. To learn more, see [Identity Lookup and Authenticate Consumer](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/use-cases/click-to-pay/repeatuser_newdevice/index.md#step-2-identity-lookup-and-authenticate-consumer). | | April 28, 2026 | Secure Card on File Integrators can now include the consumer's email and/or mobile phone number in the [Authentication](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/api-reference/apis/index.md#AccountHolderAuthenticationsAuthenticateProfile) API. This enhancement improves the Mastercard payment passkey experience by enabling a default passkey name that uses a consumer‑recognizable identifier instead of Mastercard, making passkeys easier for users to identify. | | April 8, 2026 | The Authentication Orchestration API now supports India-based URLs for sandbox and production environments and we've added region-specific test cards for testing purposes. For more information, see the [Authentication API resource](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/api-reference/apis/index.md#authentication) and related [Test Cards](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/testing/test_cases/secure_card_on_file/index.md#test-cards). | | March 3, 2026 | New reference applications for [Click to Pay](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/ref-app/ref-app-ctp/index.md), [Secure Card on File](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/ref-app/ref-app-cof/index.md), and [Guest Checkout Tokenization](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/ref-app/ref-app-gct/index.md) are now available. These fully functional, preconfigured examples show how Mastercard APIs work together in real payment flows, helping developers speed setup, validate behavior, and troubleshoot issues more easily. | | February 13, 2026 | * Cardholders can now authenticate in the issuer's mobile banking app via push notification (Click to Pay and Secure Card on file) or callback URL (Secure Card on File only). For more information, see [Fetch Authentication Methods](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/token-authentication/secure-card-on-file/by-mastercard/authentication-with-passkey/fetch-authentication-methods/index.md). * Secure Card on File integrators can choose to ID\&V cardholders before or after [creating a passkey](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/token-authentication/secure-card-on-file/by-mastercard/authentication-with-passkey/create-passkey/index.md), allowing customization of the authentication process. * Issuers now receive notifications once a payment passkey is successfully created. For more information, see [Binding](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/token-authentication/secure-card-on-file/by-mastercard/authentication-with-passkey/binding/index.md). * You can now integrate Mastercard passkeys for Secure Card on File in your native Android or iOS mobile app. For more information, see the [Mastercard Passkeys in Mobile Native Apps](https://developer.mastercard.com/mastercard-checkout-solutions/tutorial/scof_passkey_mobile_integration/index.md) tutorial. * We've changed the approach for launching the Secure Card on File authentication UI from SDK-based, to B2B API-based. For more information, see step 5 of the [Integrate with Secure Card on File](https://developer.mastercard.com/mastercard-checkout-solutions/tutorial/integrate_apis_scof/step5/index.md) tutorial. | | February 12, 2026 | Issuers as integators can now enroll cardholders for the [Mastercard Virtual Token](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/use-cases/virtual-card-tokens/card-enrollment-mvct/index.md) program using a Push account receipt based enrollment by fecthing this receipt from MDES using the Token Connect API. | | February 4, 2026 | Mastercard notifications with a TOKEN_REFRESH [reason code](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/use-cases/card-on-file/managing-tokens/index.md#reason-code-updates) now include updated token details (DPAN and expiration) whenever they change, removing the need to separately call the Checkout API to fetch the card status and token data. If the notification includes encrypted token details, use the Payload Encryption key configured during onboarding to decrypt the data. | | February 3, 2026 | The **consumer** object is now an optional parameter for the **Enroll API for Secure Card on File** . To reduce response time of [Enroll Card API](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/api-reference/apis/index.md#card), do not send the **consumer** object if the cardholder is not known. | | October 29, 2025 | A new `tokenization` object has been added to `complianceSettings` in [Enroll API](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/api-reference/apis/index.md#card). This is now **required** when tokenizing cards issued in **India** . Refer to [Test Scenario 8](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/testing/test_cases/secure_card_on_file/index.md#scenario-8) for details. | | October 16, 2025 | Initial [Mastercard Agent Pay documentation](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/use-cases/agent-pay/index.md) pages are now live, providing preliminary guidance and reference for early preview. | | August 28, 2025 | To support annual public key rotation and eliminate issues related to Key ID (KID) mapping, Mastercard has introduced [separate URLs](https://developer.mastercard.com/mastercard-checkout-solutions/tutorial/key-management/index.md#public-keys-mastercard-provides) for each key type in Sandbox and Production environments. | | July 29, 2025 | Integrators can generate Secure Card on File tokens using Mastercard Virtual Card Tokens or Click to Pay Static Tokens. For implementation details, refer to the [Tokenization of an Existing Token](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/use-cases/card-on-file/create-tokens/tokenization-of-existing-token/index.md) page. | | July 28, 2025 | For Secure Card on File, a variety of authentication mechanisms are available to Integrators to provide a secure and frictionless checkout experience to cardholders. What's new for [Third-Party Authentication](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/token-authentication/secure-card-on-file/by-third-party/index.md): * [Flexible Identity Verification](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/token-authentication/secure-card-on-file/by-third-party/identification-and-verification/identification-verification-with-mastercard/index.md): Verify cardholders using Mastercard or third-party methods. * [Device Binding Support](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/token-authentication/secure-card-on-file/by-third-party/token-binding-unbinding/index.md): Bind tokenized credentials to a device using proprietary methods. * New [Authenticate](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/api-reference/apis/index.md#authentication) API: [Authenticate transactions](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/token-authentication/secure-card-on-file/by-third-party/ta-with-3rdparty/index.md) using your preferred channel --- from passkeys to one-time codes. These enhancements give you more control over how and when authentication happens --- without compromising on security or user experience. | | July 2, 2025 | * We recently reviewed and modified the content of the entire [Secure Card on File section](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/use-cases/card-on-file/index.md) to add more clarity, consistency, and precision to achieve enhanced customer experience and improved conceptual comprehension. * We are also introducing a new [Cards Batch Enroll](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/api-reference/apis/index.md#cards-batch-enrollment) API to tokenize multiple PANs/TURs in a single request. These PANs/TURs are tokenized asynchronously, and Integrators receive a [Batch Enrollment Notification](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/api-reference/apis/index.md#notifications) (on a per-card basis) as each PAN/TUR is processed. | | June 6, 2025 | We have ready-to-use json packages for [Mastercard Chekout Solutions APIs](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/api-reference/apis/index.md) available in [Insomnia collection](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/insomnia-collection/index.md) page. Install Mastercard Auth plugin and generate a valid set of keys to test the API calls multiple times without having to write code. | | May 19, 2025 | DASP or Digital Activity Service Provider is renamed as [Technical Integrator](https://developer.mastercard.com/mastercard-checkout-solutions/tutorial/onboarding-sandbox/step4/index.md). This renaming does not impact any integrations. | | February 25, 2025 | Explore a new [tutorial for encyrption](https://developer.mastercard.com/mastercard-checkout-solutions/tutorial/perform-encryption/index.md) which provides step-by-step instructions and a code sample to encrypt an object (such as card) using the public keys from Mastercard website. These encrypted objects are required in our [APIs](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/api-reference/apis/index.md). | | February 3, 2025 | Mastercard has introduced the new [Customer Experience Guide](https://developer.mastercard.com/click-to-pay-customer-experience-guide/documentation), which provides comprehensive details on brand representation, UI components, the overall user journey, brand interactions across various touch-points, and graphical assets. This guide is available on the [Click to Pay homepage](https://developer.mastercard.com/mastercard-checkout-services/product/click-to-pay/) and in the [Guides](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/tutorials-and-guides/index.md#guides) section. | | January 30, 2025 | Mastercard is deprecating the support for `debitTokenRequested` parameter from [Merchant Registration API](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/api-reference/apis/index.md#registration), which was conditionally required for Integrators registering Digital Payment Applications (DPAs) in the US. | | November 6, 2024 | With more browsers deprecating the support for third-party cookies, Mastercard is introducing recognition token as an alternative to recognize cardholders in Click to Pay checkout. If opted, the Integrators will receive a recognition token from Mastercard network, alongside the third-party cookie dropped at the browser. For more details, see the [use cases](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/use-cases/click-to-pay/index.md) and [JavaScript methods](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/sdk-reference/index.md). | | October 31, 2024 | The [Get Batch Status](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/api-reference/apis/index.md#registration) and [DPA Notifications](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/api-reference/apis/index.md#notifications) API endpoints now provide `trid` in their responses. Work with your [Mastercard representative](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/support/index.md#get-help) for more details. | | September 12, 2024 | Technical Integrator enrolling in 'On Behalf Of' programs can onboard from *Mastercard Checkout Solutions - Sandbox* application on Mastercard Connect. Read the [tutorial](https://developer.mastercard.com/mastercard-checkout-solutions/tutorial/onboarding-sandbox/step4/index.md) for more information. | | September 3, 2024 | For Integrators that support dual payload, Mastercard will send a second payment credential in the **card** object, along with the **token** object. This payment credential should be used for additional cases outside of Click to Pay payment authorization. Read this [tutorial](https://developer.mastercard.com/mastercard-checkout-solutions/tutorial/integrate_apis/step8/index.md) and work with your Mastercard representative for more details. | | August 30, 2024 | When merchants or digital wallets participate for Token Authentication, they must provide a set of data (referred to as Digital Transaction Data) in the [Checkout API](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/api-reference/apis/index.md#checkout) to qualify for fraud liability protection in eligible markets. This data including consumer, device, and transaction related information, helps Issuers with their risk decisioning or dispute resolution. Mastercard is updating the Checkout API to include a new object, `digitalTransactionData` where this data will be included. | | August 6, 2024 | For countries that support only tokens (not FPANs), Mastercard will provide a token and Dynamic Token Verification Code (DTVC) instead of FPAN. These credentials can be used for Click to Pay payment authorization.
