Asset environment variables are meant to override the global environment variables set for all apps. These are primarily used to designate proxy configurations.
Relevant doc pages:
Thank you for the response, but this doesn't answer my question. If an Environment Variable is configured in an asset, how does that Environment Variable get called/reference in a playbook?
Is there a clear answer for this? My use case is the following.
I want to call in an authentication header from the environment variable. Is this possible and if so how. There is not clear description here and the reference docs are not helpful.
I have the exact same question. I want a place to store a password or API key and retrieve it. I don't want to store it in custom code or in the playbook.
This seems like a perfect place to put it.
If the values to store aren't particularly sensitive you may consider them in a custom list.
I _believe_ the environment variables are only visible to the App itself, not the playbook executing the app. In other words, I don't believe its possible to have the playbook extract some custom environment variable that's configured within the app settings and then pass it to the app. Instead the App would have to know to use that variable.
