User Story
Create a formula field which direct us to the LinkedIn account of a Contact. You can create supportive field to store the LinkedIn profile Id of the Contacts.
Expectation
When I click on the link, it needs to take me to the LinkedIn Account of the related Contact.
Code
HYPERLINK("https://www.linkedin.com/in/"+ LinkedIn_Profile_Id__c , "LinkedIn")
Explanation
The first argument, "https://www.linkedin.com/in/"+ LinkedIn_Profile_Id__c, specifies the URL that the hyperlink will direct to. The LinkedIn_Profile_Id__c field is concatenated to the end of the URL to create a unique link to a specific LinkedIn profile.
The second argument, "LinkedIn", is the display text for the hyperlink. When the user clicks on the text "LinkedIn", they will be redirected to the LinkedIn profile specified by the concatenated URL.
