Add caller IP context to API discussions

Share an unexpected caller IP in Slack and get its Ip2proxy classification for the investigation.

Trigger

Channel Message Received

Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.

Action

Check Proxy Status of an IP

Tool to check if an IP address is a proxy. Use after obtaining an IP to detect proxy, VPN, or Tor status.

Why this helps

Investigating unusual API traffic can pull a founder between logs, team chat, and lookup tools.

  • Keep caller IP context with the API discussion.
  • Reduce back-and-forth between log review and manual lookups.
  • Give the team a consistent check for unexpected addresses.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Ip2proxy to Notis once in the portal.
  • 2Create an automation in the portal or ask Notis in plain language.
  • 3Tell Notis to check caller IPs shared in API investigation messages and report proxy, VPN, or Tor status.
  • 4Select the Slack channel message trigger, set a channel for run reports, and test with one real caller IP.

Questions about this workflow

Does it inspect API logs directly?

No. The workflow starts from a Slack channel message and checks an IP shared there.

What can the check tell the team?

It checks whether the IP is classified as a proxy, VPN, or Tor.
