How to set environmental variables and call it from adaptive form?

Hello @mohamedn4455443 ,

If your goal is to use the values in your code you can use environment specific OSGI configurations https://docs.adobe.com/content/help/en/experience-manager-cloud-service/implementing/deploying/overview.html#runmodes

If you need to set up the url for referencing your site at different environments, it should be done at Dispatcher level https://docs.adobe.com/content/help/en/experience-manager-dispatcher/using/configuring/dispatcher-domains.html#create-dispatcher-farms-for-virtual-hosts

Alternatively, you can expose the necessary property at the page component level and set it up in the Page Properties of the root page at the specific environment.

The approaches may vary depending on your use cases.

Regards

if the Run Modes were set up accordingly at your environments, e.g. development, production, etc. (https://docs.adobe.com/content/help/en/experience-manager-64/deploying/configuring/configure-runmode...), you can get the current Run Mode at backend and it will contain the corresponding value, such as development or production. The example of getting the Run Modes in Java code https://sling.apache.org/documentation/bundles/sling-settings-org-apache-sling-settings.html
