Can I change the destination of a link without changing the short URL?

Yes! Use the `edit_link_destination` tool with the Link ID. Your agent will update the target URL in Capsulink, and the existing short link will immediately point to the new destination.

How do I check how many clicks a link received today?

Simply ask the agent to `get_link_daily_stats` and provide the Link ID. It will retrieve the click breakdown by day from your Capsulink account.

Does the integration allow using a custom back-half for my links?

Yes. When using the `shorten_url` action, you can provide the `short_url` parameter (e.g., 'summer-promo'). If available, Capsulink will create the link with that specific back-half.
