Use FME to query ArcGIS Enterprise and post to Slack

I haven’t done it, but it should be relatively straight forward

You’ll need to store the already seen services somewhere, this could be a csv, database, json file. Basically somewhere you can check what you’ve already found.

You’ll then query the base endpoint, making sure you’re requesting json

You can then break that resulting JSON down and compare it against what you have already.

For any new services that have been published since you last ran it, you will then append those to your list of existing services, then use the SlackConnector to send a message - https://docs.safe.com/fme/html/FME-Form-Documentation/FME-Transformers/Transformers/slackconnector.htm
