Slack Integration

Get instant Slack notifications with beautifully formatted submission details every time someone fills out your form.

What the Slack message looks like

Flowqen uses Slack's Block Kit to format messages. Each submission appears as a clean, structured notification:

Slack message (Block Kit)

Flowqen12:34 PM

New submission: Contact Form

name:

Jane Smith

email:

jane@example.com

message:

I'd like to learn more about your services.

Prerequisites

A Slack workspace where you have permission to install apps
Admin or owner access to create an Incoming Webhook
A Flowqen form ready to receive submissions

Setup

Create a Slack app with Incoming Webhooks

Go to api.slack.com/messaging/webhooks and follow the guide to create a new Slack app. Then navigate to Incoming Webhooks in the app settings and toggle it On.

Add a webhook to your workspace

Click "Add New Webhook to Workspace", pick the channel you want notifications posted to, and authorize. Slack will generate a unique webhook URL.

Your webhook URL will look like this:

Webhook URL

https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX

Configure in Flowqen

Go to your form's Settings tab, then Integrations. Scroll down to the Slack section and:

Toggle "Enable Slack notifications" on
Paste your Webhook URL
Click Save Settings, then "Send Test Message" to verify

Payload

Under the hood, Flowqen sends a JSON payload using Slack's Block Kit format. Here's what the structure looks like:

POSThttps://hooks.slack.com/services/T.../B.../XXXX

Block Kit payload

{
  "blocks": [
    {
      "type": "header",
      "text": {
        "type": "plain_text",
        "text": "New submission: Contact Form"
      }
    },
    {
      "type": "section",
      "fields": [
        { "type": "mrkdwn", "text": "*name:*\nJane Smith" },
        { "type": "mrkdwn", "text": "*email:*\njane@example.com" },
        { "type": "mrkdwn", "text": "*message:*\nI'd like to learn more..." }
      ]
    },
    {
      "type": "context",
      "elements": [
        {
          "type": "mrkdwn",
          "text": "Submitted via <https://flowqen.com|Flowqen> | 4/3/2026, 12:34 PM"
        }
      ]
    }
  ]
}

Good to know

Slack notifications are fire-and-forget — they never delay or block the form submission
Up to 10 form fields are included in the message (values truncated at 200 characters)
Your webhook URL is stored securely and never exposed to form submitters
Use the "Send Test Message" button to verify the integration before going live
You can use both Slack and email notifications at the same time
