That link is generally. In ‘Add a Certificate’ section in LinkedIn, you need to provide the link for your certification. But the only link that is available is a ‘Verify’ link, that requires you to give your Certificate-Id and username. But you cannot add this information on LinkedIn certificate section.

CodeChef should host our certificates permanently and provide a link that can be shared to anyone.
