# June 2026 Pre-Release Notes source: https://developer.mastercard.com/mdes-pre-digitization/documentation/pre-release-notes/prereleasenote_support_decisioning_data_june26/index.md ## Release Change Summary {#release-change-summary} MDES is enhancing the Pre-Digitization API to enable issuers to: * Provide relevant cardholder authentication methods based on the device used and enhanced decisioning info. * Fine-tune the OTP messages to their cardholders based on the device initiating the tokenization request. ##### Impacted APIs: {#impacted-apis} * Request Activation Methods (RAM) * Deliver Activation Code  (DAC) ## Release Timeline {#release-timeline} * MTF: 6 May 2026 * Production: 10 June 2026 ### Impacted Market {#impacted-market} * Availability: Global ## Change 1 - Enhanced Decisioning Info in RAM API {#change-1---enhanced-decisioning-info-in-ram-api} To enable issuers to provide the most relevant cardholder authentication methods, MDES will now include device information and the wallet provider's recommended decision in the Request Activation Methods API during the tokenization flow. This information was previously shared through the RAM API during [post‑tokenization authentication](https://developer.mastercard.com/mdes-pre-digitization/documentation/pre-release-notes/prereleasenote_taf_jan25/) and through the Authorize Service API. Note: There is no update to the API specification. ## Change 2 - Introduction of Device Info in DAC API {#change-2---introduction-of-device-info-in-dac-api} To enable issuers to fine-tune OTP messages for their cardholders based on the device used for the tokenization request, the complex object `deviceInfo` will be added to the Deliver Activation Code request. #### Object and Parameters {#object-and-parameters} | Field and Description | Data Type | Min Length | Max Length | Required | |------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------|------------|------------|----------| | **deviceInfo** Contains device information where the card is digitized during the tokenization use case, or the cardholder is being authenticated for post‑tokenization authentication. | Object | NA | NA | No | | **deviceName** The name that the account holder has associated to the device with the payment app provider. | String | 1 | 64 | No | | **serialNumber** The serial number of the device.
