Going Live {#restgs-sdk-go-live-shared-secret-intro}
====================================================

![](/content/dam/documentation/cybs/en-us/topics/platform/rest/getting-started/images/restgs-sdk-flow-6-750x200.svg/jcr:content/renditions/original)  
When you are ready to process payments in a live environment, you must transition your account to the live status with a valid configuration for your chosen payment processor. When your account is live, your transaction data flows through the production `Cybersource` gateway, to your processor, and on to the appropriate payment network.  
To transition your account:

1. Sign up for a merchant account.
2. [Contact Sales](https://www.cybersource.com/en-us/contact-us/sales.md "") to establish a contract with `Cybersource` that enables you to process real transactions and receive support.
3. Submit a merchant ID (MID) activation request.

It can take up to three business days for the MID to become active.

Step 6A: Create a Merchant ID {#restgs-sdk-go-live-shared-secret-mid}
=====================================================================

Your merchant ID (MID) identifies you and your transactions, which requires you to include it in each transaction request. When you signed up for a sandbox account, you received a merchant ID for testing purposes. If you choose, you can use that merchant ID as your production ID.  
Follow these steps to sign up for a merchant account in order to create a production MID:

1. Go to the `Business Center` [Sandbox Account Sign Up](https://developer.cybersource.com/hello-world/sandbox.md "") page, enter the required information, and click **Create Account**.  
   Choose your merchant ID name. It cannot be changed. This name is not visible to your customers.
2. Review your information entered, especially your business email address. Your merchant ID registration information will be sent to the email entered on this form.
   3. Look for an email from customer support titled: *`Cybersource` Merchant Evaluation Account*.  
      This email contains your organization ID and contact email associated with your MID.
   4. Look for an email titled: *Merchant Registration Details* . Click the **Set up your username and password now** link.  
      Your browser opens the New User Sign Up wizard.
3. Enter the organization ID and contact email you supplied previously. Follow the wizard pages to add your name, a username, and password.
   6. Log in to the `Business Center`.  
      When you log in for the first time, you will be asked to identify yourself through a system-generated email that is sent to your email account.
4. Look for an email titled: *`Cybersource` Identification Code*. Save the passcode in the email.
5. Enter the passcode on the Verify your Identity page. You are directed to the `Business Center` home page.

You have successfully created a merchant ID and merchant account.

Step 6B: Activate Your Merchant ID {#restgs-sdk-go-live-mid-shared-secret-activation}
=====================================================================================

The activation process, also known as *going live*, transitions your MID and account from test status to live status, enabling you to process real transactions. It can take up to three business days for your MID to become active.  
To transition your account, complete these steps:
1. Sign in to the [Support Center](https://support.visaacceptance.com/ "") as an administrator.
   2. Enter your credentials and log in to your test environment. The organization ID is your MID.  
      ![](/content/dam/documentation/cybs/en-us/topics/platform/rest/getting-started/images/restgs-test-login.png/jcr:content/renditions/original)
2. In the `Business Center`, go to **Support Cases \> MID Configuration Request**. The MID Configuration Request page should be open.
3. Click **MID Activation**.
4. In the **Description** field, enter the merchant ID that you want to take live.
   6. Choose a processor configuration, and enter the name of your processor.  
      If you are unsure of the processor name, contact your merchant service provider or your merchant acquiring bank.
5. Choose the environments to which this change applies (test or production).
6. Click **Service Enablement** and list the products and services that you intend to use.
7. Click **Submit**.
