If you are part of a large team which uses Remote Config, it is often hard to keep track of who is publishing Remote Config in your team and when.
To simplify collaborative workflows, you can be alerted using your favorite mechanism (Slack or Email) in near real time. The Remote Config REST API together with a Remote Config background trigger in Cloud Functions for Firebase can let you send a notification whenever your Remote Config template changes.
eBay recently open sourced their implementation for how they use Cloud Functions with Remote Config to publish a diff of previous versus new Remote Config templates into a Slack channel.
