# Ptengine Parameters List

## Ptengine Parameters List

When tag distribution in tag management tools such as Google Tag Manager (GTM) is limited, and settings are configured so that tags are not distributed to URLs containing Ptengine's unique parameters, some features of Ptengine may not be available.

For example, if you specify a URL in GTM's trigger settings with "Some Pageviews" and "Page URL equals," URLs containing parameters will be excluded.

To resolve this issue, when using "Some Pageviews," we recommend using "contains" or "starts with" as the matching rule instead of "equals."

Below is a list of parameters issued when using Ptengine for your reference.

## Parameters List

When using GTM to limit the tag distribution range (i.e., placing tags only on some pages), please check whether the following parameter URLs are included in the distribution conditions.

Required when viewing web heatmaps ptengine\_heatmap\_token pt\_lang

Required when configuring visual events ptengine-event-explore target-url ptengine-url-type

Required when editing your site in the Experience editor ptengine\_engage\_editor\_token poster\_uid

Required when previewing an Experience hasAntiFlicker preview\_ptx\_token hasInline hasRedirect

## Examples

Ptengine has a monthly PV limit for measurement depending on the plan. Therefore, when you want to measure only some pages instead of the entire site, there are cases where you limit the tag distribution range in GTM.

If you set the range under conditions that do not include the above parameter URLs, screens with the above parameters will not be able to open.

Example:

Trigger condition: When set with Page URL equals the following URL: [https://www.example.com/](/en/faq/tag-and-domain/ptengine-parameters.md)

URLs that will not trigger: [https://www.example.com/?utm\_source=abc](/en/faq/tag-and-domain/ptengine-parameters.md) [https://www.example.com/?utm\_source=abcptengine\_heatmap\_token\_xxxxx](/en/faq/tag-and-domain/ptengine-parameters.md)

For other cases where tags are placed in GTM but are not measured correctly, please check [this article](/en/faq/tag-and-domain/ptengine-parameters.md).
