# Release Notes October 2025
source: https://developer.mastercard.com/mdes-customer-service/documentation/release-history/release-notes-oct2025/index.md

## Release Change Summary {#release-change-summary}

The MDES Customer Service will be enhanced to support **additional filters** and a **compact response** option when searching using different identifiers including **Account PAN** , **Alternate Account Identifier** , **Payment App Instance ID** , and **Virtual Card Number**. These improvements help issuers to retrieve only the filtered data, reducing the volume of search results and improving efficiency.

### Release Dates {#release-dates}

* MTF - 1 October 2025
* Production - 8 October 2025

### Release Details {#release-details}

## Change 1: Additional Search Filters {#change-1-additional-search-filters}

The Search API request will include new optional parameters to filter the tokens returned to the issuer based on their values. For example, if the request contains TokenType = "S", only Embedded Secure Element (S) tokens associated with the FPAN will be returned. Any Card on File (F) or Mastercard Cloud-Based Payments (C) tokens will be excluded from the response.

* TokenStatusCodes
* TokenTypes
* TokenRequestorId

Using the same search filter condition in two different filter fields will return a null or empty response. For example, if you pass the filters **ExcludeDeletedIndicator = true** (to exclude deleted tokens) and **StatusCode = D** (to include only deleted tokens) in the request, the system will return a null or empty response.

API Reference: `GET /{id}/search`

## Change 2: Compact Search Response {#change-2-compact-search-response}

The Search API request will include the new optional parameter CompactResponse. When enabled, Mastercard will return the list of associated tokens with only the most relevant fields as listed below.

* TokenUniqueReference
* PrimaryAccountNumberUniqueReference
* CurrentStatusCode
* TokenSuffix
* TokenRequestorId
* WalletId
* TokenType
* StorageTechnology
* TokenDeletedFromConsumerApp
* TokenRequestorConsumerFacingEntityName

Note:   

* This field can be used in conjunction with the new parameters specified in Change 1.
