## Overview {#overview}

### What You'll Learn: {#what-youll-learn}

* Request MTF access

### What you'll need: {#what-youll-need}

Before testing in the MTF environment:

* You must have a CIS project open.
* You must have received your CIS project number (CIS-xxxx-xxxx) from Mastercard.

### APIs Used in this Tutorial {#apis-used-in-this-tutorial}

* MDES Customer Service MTF

## Select an existing project {#select-an-existing-project}

1. Log in to your Mastercard developers account and select the project.
2. Click **Open Project** to see the project details. ![](https://static.developer.mastercard.com/content/mdes-customer-service/documentation/tutorials/tutorial-5/mtf-projects-summary.png)

## Request Access {#request-access}

1. On the Project summary page, click **Request Production Access**.

## Project Credentials {#project-credentials}

1. Enter **Key alias** and **Keystore password** . A key alias is a label for specific key within a keystore. Ensure that you make a note of the key alias and the keystore password as you will need this information when you send the API request to Mastercard. ![](https://static.developer.mastercard.com/content/mdes-customer-service/documentation/tutorials/tutorial-5/project-credentials.png)
2. Click **Proceed**.

Note:   

* To use a custom CSR to generate the project keys, click **Skip this step** , and continue with the project creation. Refer to generating [Adding Keys and CSR](https://developer.mastercard.com/mdes-customer-service/documentation/tutorials/add-key/index.md).
* The OAuth keys can either be renewed or rotated. Refer to the [Renew OAuth Keys](https://developer.mastercard.com/platform/documentation/getting-started-with-mastercard-apis/renewing-your-keys/renew-oauth-keys/) topic for detailed instructions.

## Additional Credentials {#additional-credentials}

This section is to configure the data level encryption and decryption keys.

1. As this service requires only the Client Encryption key, it will be generated automatically when you proceed. Click **Update Project** . Project key creation process starts and completes in a few seconds. ![](https://static.developer.mastercard.com/content/mdes-customer-service/documentation/tutorials/tutorial-5/testing-mtf-add-cred.png) Note: Depending on the service you select, you will be able to generate additional credentials on this page.

## Download MTF Keys {#download-mtf-keys}

1. To download the key information, click **Download Key File** . ![](https://static.developer.mastercard.com/content/mdes-customer-service/documentation/tutorials/tutorial-5/update-project-mtf.png) The key file has the following information:

* The OAuth Signing key - P12 file
* The client encryption key - pem file - Issuer will use public key to encrypt data in the response.

2. Click **Open Project** to see the project details:
   1. Sandbox Client ID
   2. Production Client ID
   3. Project APIs and Sandbox and Production status. ![](https://static.developer.mastercard.com/content/mdes-customer-service/documentation/tutorials/tutorial-5/requestprodaccess-mtfs-projectdetails.png)

The encryption key for the MDES Customer Service MTF API is displayed under the Production Credentials section.
Note: The encryption keys cannot be renewed after expiry. We recommend you add a new key before the existing key expires. Refer to the [Rotate a Client Encryption Key](https://developer.mastercard.com/platform/documentation/getting-started-with-mastercard-apis/renewing-your-keys/rotate-encryption-keys/#1-rotate-a-client-encryption-key) topic for detailed instructions.

## Ready to Test in MTF {#ready-to-test-in-mtf}

You must retrieve your Mastercard API Production Client ID (part of the Consumer Key) and provide it to your CIS IM.

1. From the Mastercard Developers project summary page, navigate to Production Credentials.
2. Under OAuth 1.0a project keys, next to the consumer key, click the copy icon to copy the Consumer Key and provide it to your CIS IM. ![](https://static.developer.mastercard.com/content/mdes-customer-service/documentation/tutorials/tutorial-5/sandbox_prod_cred.png)

After you are onboarded to MTF, you are ready to test. Refer to the [Environment Domains](https://developer.mastercard.com/mdes-customer-service/documentation/environment-domains/index.md) page for the URLs.
Note:   

* If you see Production Status is "Under Review" or "Declined" please contact Mastercard implementation manager and request for approval.   
* If Production Status is "Ready" then contact Mastercard implementation engineer or manager for further onboarding.
