Hello,

       Is there any documentation or a link i could visit to

understand the concept of how the formatter URL works in wikibase for external identifiers and what extensions or configuration needs to be done to enable it. On wikidata we see that any external identifier with a value on click redirects to the corresponding external domain page and this functionality is missing from our local installation of mediawiki with wikibase. Any assistance would be of help.

Sorry for only getting back to you now. You can see Wikidata's config here: https://noc.wikimedia.org/conf/highlight.php?file=Wikibase-production.php There you will see a config for formatterUrlProperty which defines the property that us used to hold the formatter URL for a property. On Wikidata it is then used in this way: https://www.wikidata.org/wiki/Property:P345#P1630
