What the deeplink module basically does is trigger a microflow based on a URL. Some use cases for this might be:

• Linking a user to a specific page from an e-mail, for instance, to confirm their registration
• Allowing one application to seamlessly link to another
• “Forgot password” functionality
• etc.

Hi Karthi NS,

The use of Deeplink is, 

• Create persistent links to view only pages, which you can use in emails or on your website.
• Provide a colleague a link to a certain object instead of describing the necessary navigation steps.
• Generate confirmation links that can be emailed to the user.

For more information, you can refer to this: https://docs.mendix.com/appstore/modules/deep-link

Thank you.

deep link is any link that directs a user past the home page of a website or app to content inside of it.
