Quick answer

Create an Incoming Webhook in Slack for the channel you want, copy the generated webhook URL, then paste it into your form's Slack & Discord notification field in FormBridge (available on Pro and above). Every submission after that posts a message to the channel automatically.

Email notifications work, but they're easy to miss in a crowded inbox. If your team already lives in Slack, routing form submissions there means new leads, support requests, or applications show up where people are actually looking.

Step 1: Create a Slack incoming webhook

This part happens entirely inside Slack, not FormBridge. In your Slack workspace:

  1. Go to api.slack.com/apps and click Create New AppFrom scratch.
  2. Name it something like "Website Forms" and select your workspace.
  3. Open Incoming Webhooks in the app settings and toggle it on.
  4. Click Add New Webhook to Workspace, choose the channel that should receive submissions, and authorize it.
  5. Copy the generated URL — it looks like https://hooks.slack.com/services/T000/B000/XXXXXXXX.

Keep that URL private; anyone who has it can post messages to the channel.

Step 2: Add it to your form in FormBridge

In your FormBridge dashboard, open the form you want to connect and go to its Slack & Discord notification settings. Paste the webhook URL into the Slack field and save. There's nothing else to configure — no scopes to request, no bot to invite.

This feature is available on FormBridge's Pro plan ($9/mo) and above; it isn't included on the Free plan.

Step 3: Test it

Submit the live form yourself, or send a quick test request:

curl -X POST https://app.formbridge.ai/api/forms/fb_8h2k9p \
  -d "full-name=Test User" \
  -d "email=test@example.com" \
  -d "message=Testing Slack notifications"

Within a few seconds, a message should land in the channel you connected. If it doesn't show up, double-check the webhook URL was pasted in full and that the Slack app's webhook is still active — deleting or reinstalling the Slack app invalidates the old URL.

Keep email running too

Slack notifications don't require you to give up email. Most teams keep a recipient list for record-keeping and searchability, and add Slack for the immediate "someone just submitted the form" ping. Each field submitted still shows up in your FormBridge inbox regardless of where the notification goes, along with the submission's full processing log — received, spam-checked, notified.

Frequently asked

Do I lose email notifications if I turn on Slack?

No. Slack notifications run alongside your existing recipient list and autoresponder settings — you can keep email, add Slack, or do both. Nothing about your notification setup is replaced automatically.

Which FormBridge plan includes Slack notifications?

Slack and Discord notifications are available starting on the Pro plan ($9/mo). The Free plan does not include this feature.

Can I post to more than one Slack channel per form?

Each form supports one webhook URL, so one channel per form. If you want submissions in two channels, you'd need two forms or a second automation on the Slack side that relays the message.

Key facts

  • Slack and Discord notifications are available on FormBridge's Pro plan ($9/mo) and above, not on the Free plan.
  • Each FormBridge form connects to one Slack channel via one webhook URL, added from the form's notification settings.
  • FormBridge's Free plan includes 1,000 submissions per month across 2 forms; Pro raises that to 25,000 submissions across 20 forms.
