In a Slack app, you can specify a slash command and set a webhook such as one from webhook.site. Slack expects an HMAC check, and in the app you can find a shared secret to use for the webhook.site-side re-calculation. It works as needed using the new hmac() function, and the script will exit if the received signature and locally re-calculated signature don't match. The rest of the script assembles an array using the request.form params that come from Slack, converts it to json, and uploads it to a web service for reference. In our case, we have a Slack command "/iam" which lets us enter something like `/iam @acme working on the server` to indicate our status to peers and for linking to Time and Expense entries in our database.
