I am still not done, I am actually testing here, because I am not sure about the correct syntax. I will let you know once I get it to work so you can take a look at it.

@vsoch so far I tried different approaches and none worked? any idea what am I doing wrong here? do you think it is the syntax or something else?

[vsoch]

For GitHub actions?

Oh for travis. You should be able to define it in Travis settings (secrets as they show) and then reference it as an environment variable.

I'd probably encrypt it https://docs.travis-ci.com/user/environment-variables/#defining-encrypted-variables-in-travisyml
