I have a requirement in which when the vision client is updated, my client tag should be updated with a value of 1.

Please let me know if you have any ideas to fulfill the requirement of executing a script only when the Ignition vision client is updated.

There's nothing that will do that. However, if you set project update mode to None, you can use scripting to perform a client update as described for [system.vision.updateProject()](https://docs.inductiveautomation.com/display/DOC81/system.vision.updateProject). Such a script would be able to perform whatever other special actions you want.

The `ProjectUpdateAvailable` tag could be watched to know when an update is _pending_, but unless you script the actual update as Phil mentioned, you won't know when the update actually happened.
