Tip of the day with Slack integrations: using metadata
You can build highly interactive and rich applications with Slack.
If you need to store additional metadata not visible to users within messages, you can use message “metadata”.
Then you can reference external information stored within that metadata programmatically! 🏆
Most likely you cannot read back that information by default, so remember this tip:
▶ add to your API call URL the parameter “include_all_metadata=true”
The metadata will then be available to you!
