Where is the best place to store things like API keys, etc when creating functions?
More context:
I’m writing a function to handle email confirmation of a user authenticated with email/password, and I’d like to use Mailgun for this. The mailgun.js package doesn’t appear to be supported by Realm, so I figured I could just use a standard ajax library like axios to make the Mailgun API calls. However, I’d still want a way of securely storing the API keys I need to make the calls. Any suggestions?
