Sending beacon: xhr vs script

rigor

17-09-2020

I have AppMeasurement 2.17.0 and it sometimes sends beacons as (1) AJAX POST request and sometimes it dynamically (2) adds <script> to the page (with the same URL as AJAX request) and that results in a GET request.

In case of 1 the data is encapsulated in the request body, and in case of 2 the data is sent in request parameters.

Why is that so, and is it possible to configure it to always send the beacon as AJAX POST?

 

I would like to have it that way, because it makes testing track calls with tools such as Cypress easier. Cypress, for example, is capable only of detecting AJAX requests.

This was addressed in another post: https://experienceleaguecommunities.adobe.com/t5/adobe-analytics-questions/difference-between-post-v...

Basically, AppMeasurement itself decides which method to use. As far as I know, there is no user-configurable setting to force AppMeasurement to always use POST.

The next best thing that you can consider is s.useBeacon: https://docs.adobe.com/content/help/en/analytics/implementation/vars/config-vars/usebeacon.html
