How it works

1

Link your Fillout form to Slack

Open your form in Fillout and head to the Integrate tab, then click Slack.Screenshot 2025-11-17 at 2.36.32 PM.pngLabel your Slack integration, then Connect to Slack. The label you choose won’t matter. It’s just for identifying which Slack workspace you connected to in case you reuse the connection on other forms.
2

Choose a channel

Select the Channel from your workspace you want to send notifications to, e.g. #random or #general.Screenshot of the Slack form creation pageFinish setup That’s it! You will now receive notifications on the Slack channel whenever a respondent completes your form.
3

Publish and share

Remember to Publish your form to make the changes reflect.

Message formatting

The default option, Send all fields, sends form responses in a nicely formatted message in your channel. You’ll see responses like this in Slack: Screenshot of the Slack form creation page
We recommend this option, since Fillout handles ordering the questions properly and you won’t need to make changes if you add more questions to your form.

Send a custom message to Slack

Choose the other option, Custom message, if you want to specify the exact information that gets sent to Slack. Click or type @ to reference questions or fields in your form. Screenshot2025-02-12at3.35.29PM.png copy.jpg
You can format Slack messages using Slack’s formatting markdown language.

Specify a condition

You can run your integration only when a specific condition is met. Check out this guide.
