Slack Setup Guide
Send form submission notifications to Slack channels. Create an Incoming Webhook and receive formatted messages.
Setup steps
Go to api.slack.com/apps and click Create New App. Select From scratch when prompted.
Enter a name for the app (e.g., "FormBlade") and select the Slack workspace where you want to receive notifications. Click Create App.
In the app settings page, click Incoming Webhooks in the left sidebar (under "Features").
Toggle Activate Incoming Webhooks to On.
Scroll down and click Add New Webhook to Workspace. Select the channel where you want notifications to appear and click Allow.
After authorizing, you'll see a new webhook URL. It starts with:
https://hooks.slack.com/services/T00000000/B00000000/XXXX...
Copy this URL.
Log in to your FormBlade dashboard. Open the form you want to configure, go to Settings → Notifications, and click Slack. Paste the webhook URL and click Save.
Click Send test message in the Slack notification settings. You should see a formatted message appear in your chosen Slack channel within a few seconds.
Tips
Messages are formatted using Slack Block Kit, displaying each form field label and its submitted value in a clean, readable layout.
Multiple forms
You can use the same Slack webhook URL on multiple forms. Each notification includes the form name in the header, so you can tell which form the submission came from. This is handy when you want all form alerts in one Slack channel.
