Bridge External Tools to Slack

Data lives in third-party tools but your team sees Slack. Notis webhooks post external updates so your team stays informed.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Action

Post message to channel

Deprecated: posts a message to a slack channel, direct message, or private channel. use `send message` instead.

Why this helps

Updates from other tools never reach your Slack, forcing you to check multiple dashboards and manually share information.

  • Centralize all updates in Slack
  • Eliminate manual notifications
  • Keep team informed automatically

Setup

Build it in a few focused steps.

  • 1Create a Notis automation with a webhook trigger
  • 2Copy the webhook URL that Notis provides
  • 3Configure your external tool or backend to send data to that URL (REST POST)
  • 4Specify the Slack channel where data should appear
  • 5Notis will post incoming webhook data as Slack messages automatically

Questions about this workflow

What kind of webhooks can I send?

Any JSON data. Include fields you want visible, and Notis formats them for Slack.

Do I need technical setup?

If your tool has webhook support, yes. If not, you can ask a developer to send data to Notis webhooks.

Can I customize the message format?

Yes. Notis can format webhook data using your description. Specify how data should appear.
