Data Flow Matchers

Data flows are request matchers that can be used to assign tracking purposes onto matching requests.

Host MatchersCopy Anchor Link

These are hosts, such as example.com and [::1]. The data flow creation dialog automatically extracts hosts from any absolute or any-protocol URL.

Path MatchersCopy Anchor Link

These are full or partial URL paths. The following examples show the allowed formats:

• Absolute: https://example.com/path/to/resource
• Any-protocol: //www.example.com/path/to/resource
• Same-site: /path/to/resource or path/to/resource (this only matches for requests to the same site as the current page)
• Any-site: ///path/to/resource

Note: Absolute Path matchers using the data: URI scheme are not supported at this time.

Query Parameter MatchersCopy Anchor Link

These are URL query parameters, such as ?utm_source. Value constraints can be added to matchers, such as ?utm_source=example, which will match requests that have the query parameter utm_source starting with the value example.

Regular Expression MatchersCopy Anchor Link

These matchers can be used to match any part of a request, and are applied against full URLs. An example of a regular expression matcher is ^https?://example\.com/path/to/resource, which will match requests starting with https://example.com/path/to/resource or http://example.com/path/to/resource. Note that Regular Expression matchers can have significant performance impact, so be sure to test the performance impact on your site when adding many of these matchers.
