Customize the API Gateway Domain

By default, WSO2 API Cloud provides gateway.api.cloud.wso2.com/t/<your organization id>/ as the Gateway domain. The region of the default Gateway domain is US East. If necessary, you can customize the Gateway domain to be more representative of your company or personal branding, and you can also have multiple gateway custom domains per region. Customizing the Gateway allows you to route your traffic to a different AWS region.

You can perform any of the following actions to customize the API Gateway domain depending on your requirement:

• Create a new Gateway custom domain
• Update certificates of an existing Gateway custom domain
• Delete a Gateway domain

Create a new Gateway custom domain

WSO2 API Cloud currently has regional gateways in US East, US West, Brazil (São Paulo), EU (Ireland), EU (Frankfurt), and Sydney.

Follow the steps below to create a new API Gateway domain in a preferred region.

1. Sign in to WSO2 API Cloud https://api.cloud.wso2.com as an admin user.

2. On the API Publisher, click Configure and then select Custom URL from the drop-down menu.
   This displays the Manage Custom Domains page.
   

3. Under API Gateway, click Add. This displays the Add New Gateway Custom Domain dialog box.

4. Select a required Region for the Gateway custom domain, then specify a Domain Name for the Gateway, and then click Verify. This checks whether the CNAME record exists for the specified URL.
   
   If the CNAME verification is successful, you will see the following dialog box:
   

5. For each field, upload a valid file that meets the specified requirements.

   Field	Requirements
   SSL Certificate	This certificate file must satisfy the following requirements: Should be in X509 format. Should not be expired. Should be issued directly or by a wild card entry for a provided custom URL. For example, In the direct method, if the CNAME is gateway.wso2.com, the issued SSL file must contain gateway.wso2.com. In the wildcard method, if the CNAME is gateway.wso2.com, the issued SSL file should be *.wso2.com.
   SSL Key File	The private key of the certificate, which should be encrypted in the RSA format.
   Chain File	The chain file to be used if the SSL connection to your custom URL fails with the SSL Certificate and SSL Key File .

   This confirms that you have successfully changed the Gateway domain name.

   Tip

   It takes approximately 10 minutes for the changes to apply. This is because adding the configurations and restarting the load balancers can take some time.

7. Go to the API Store, select an API and note the new API URLs on the API Overview page. You will see the new API Gateway URL.
