+title: "Wildcard URL support in website live-chat campaigns"
+---
+
+The website live-chat campaigns support wild card URL patterns. While building a URL pattern, consider the following behavior in mind.
+
+In Chatwoot, every URL pattern should start with `http://` or `https://`.
+
+### Running the campaign on the exact URL
+
+If you add an exact URL like `https://chatwoot.com/app`, then the URLs with trailing slashes or the URL params or the hash params would not match.
+  - `https://chatwoot.com/app`
+  - `https://chatwoot.com/app?test_param=test_value`
+
+### Running the campaign ignoring the URL parameters
+
+To ignore the URL params or hash params, you can add a trailing slash in the URL. For eg: `[https://chatwoot.com/app/](https://chatwoot.com/app/)` would match all the following URLs.
+  - `https://chatwoot.com/app/`
+  - `https://chatwoot.com/app`
+  - `https://chatwoot.com/app/?test=1`
+  - `https://chatwoot.com/app/#test`
+
+### Running the campaign in all sub-directories
+
+You can use the `*` character in the URL if you want to match all the sub-directories. For eg: `https://chatwoot.com/*` would match to the following URLs
+ - `https://chatwoot.com/`
+ - `https://chatwoot.com/app`
+ - `https://chatwoot.com/app/subdirectory`
+
+### Running the campaign in all subdomains
+
+To match the current domain and subdomains, you can use the pattern `{*.}?` in the URL. For eg: `https://{*.}?chatwoot.com/` would match to the following URLs
+ - `https://chatwoot.com`
+ - `https://app.chatwoot.com`
+ - `https://www.chatwoot.com`
