Hi Patrick, Yes! There is a way.

 

When you use the Web Companion you are actually just dropping a cookie to tell Tealium to switch environment:

Therefore, you can write a pre-loader extension to drop that cookie for you based on a query-string parameter. This unsupported but you can try using my extensions as a javascript extension scoped to 'pre-loader':

### PROFILE/ENVIRONMENT SWITCHING EXTENSION ###
###############################################

Author : roshan@tealium.com

Notes:
This extension:

- Allows users to change profile or environment by adding 'tealium_env=[env name]':
    
    e.g. greatsite.co.uk?tealium_env=qa
    e.g. greatsite.co.uk?tealium_env=dev    

- Allows users to change profile by adding 'tealium_profile=[profile name]' 'tealium_env=[env name]':

    Note: If you don't change environment Tealium will force a change of environment to ensure the profile will change

    e.g. greatsite.co.uk?tealium_profile=greatprofile    
    e.g. greatsite.co.uk?tealium_profile=greatprofile&tealium_env=qa    

- Allows you to bust the cache by adding 'tealium_cb = 'true' 

    Note : This won't work without changing to a different environment to the original page

    e.g. greatsite.co.uk?tealium_env=dev&tealium_cb=true
    e.g. greatsite.co.uk?tealium_env=dev&tealium_profile=greatprofile&tealium_cb=true

    Note: You cannot cachebust on 'prod' environments

- To remove all environment switching, just add 'tealium_env=clear' to your query-string:

    e.g. greatsite.co.uk?tealium_env=clear

Is there a way to switch Tealium environment without using the Tealium companion? Using a query string parameter for example? Otherwise is impossible to make tests with IE below version 10

Thanks, very useful.

There was a change to Web Companion back mid-July which removed the utag_env cookie capability. You can re-establish enabling the utag_env cookie capability by turning On the "Web Companion" Publish Configuration option then publishing to the prod environment:image.png
