# MDES Digital Enablement API 
source: https://developer.mastercard.com/mdes-digital-enablement/documentation/index.md

## Overview {#overview}

MDES allows a merchant to tokenize Account PANs entered by consumers or existing Account PANs held on file, replacing each PAN with a unique MDES token (subject to issuer participation). These tokens can be used for e‑commerce and in-app transactions in the same way as Account PANs.

#### [MDES for Merchants](https://developer.mastercard.com/mdes-digital-enablement/documentation/use-cases/mdes-for-merchants-use-cases/index.md) {#mdes-for-merchantsdocumentationuse-casesmdes-for-merchants-use-cases}

Eligible merchants acting as Token Requestors can benefit from connectivity to participating Mastercard issuers facilitating tokenization of Mastercard and Maestro cards when used in a merchant website, mobile application, or other card on file platform.

#### [Push Provisioning using Token Connect](https://developer.mastercard.com/mdes-digital-enablement/documentation/use-cases/push-provisioning-merchant-use-case/index.md) {#push-provisioning-using-token-connectdocumentationuse-casespush-provisioning-merchant-use-case}

Using Token Connect, consumers can push payment information from their issuer's website or mobile banking app to participating merchants' websites and apps for secure, convenient checkouts online.
Note: If you are a new customer looking to start a tokenization project, refer to [Secure Card on File](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/use-cases/card-on-file) available on Mastercard Checkout Solutions.
