Enable My Domain on Salesforce
Before you can install Mambo Merge (or any Lightning Web Component) in your Salesforce, you will need to enable the My Domain feature in your Salesforce org. The My Domain feature customizes the url for your Salesforce to help your employees feel secure that they are using your company’s official Salesforce.
To start, you’ll need to find an available domain name and sign up for it.
From Setup, enter My Domain in the Quick Find box, then select My Domain.
Enter the subdomain name you want to use within the sample URL.
Select Check Availability. If your name is already taken, choose a different one.
Select Register Domain. You receive a confirmation email from Salesforce when your new domain is ready for testing.
Test your domain name and deploy it to your org.
Click the URL in the confirmation email to log in to Salesforce using your new domain. Alternatively, from Setup, enter My Domain in the Quick Find box, select My Domain, and then select Click here to login.
Test the new domain by clicking tabs and links within your org. Notice that all pages show your new domain name.
To roll out the new domain name to your org, from Setup, enter My Domain in the Quick Find box, select My Domain, and then select Deploy to Users. The domain is activated immediately, and your users are redirected to pages with the new domain.
