How Do I Automate Slack Notifications with n8n?

Overview

Feedspace integrates with Slack through n8n using webhooks. When a new testimonial is submitted in Feedspace, a webhook fires to your n8n workflow, which then posts a message to a Slack channel automatically.

Note: Automation through webhooks is available only on Professional and Business Plans in Feedspace.

Step 1: Create a Workflow in n8n

1. Log in to your n8n instance (cloud or self-hosted) and click + New Workflow.
2. Give your workflow a name, e.g., Feedspace to Slack Notifications.

Step 2: Add a Webhook Trigger Node

1. Click Add first step and search for Webhook.
2. Select the Webhook trigger node.
3. Set HTTP Method to POST.
4. Copy the Webhook URL shown in the node panel — you will need this in the next step.
5. Click Listen for test event to put the node into test mode.

Step 3: Register the Webhook in Feedspace

1. In your Feedspace workspace, go to Automation in the left sidebar.
2. Click the Webhooks tab.
3. Click Add Webhook and paste your n8n Webhook URL.
4. Select the event New Testimonial.
5. Click Save. Feedspace will now POST testimonial data to n8n each time a new testimonial arrives.

Step 4: Add a Slack Node

1. Back in n8n, click + after the Webhook node to add an action.
2. Search for Slack and select it.
3. Choose Send a Message as the operation.
4. Click Create new credential and connect your Slack account by entering an OAuth token or selecting your workspace.
5. Select the Channel where notifications should be posted.
6. Compose the Message Text using dynamic fields from the webhook body. For example:
   • New testimonial from {{ $json.reviewer_name }}: {{ $json.star_rating }} stars. {{ $json.testimonial_url }}

Step 5: Test and Activate the Workflow

Submit a test testimonial in Feedspace. The webhook fires and the Webhook node in n8n receives the data. Confirm the Slack message arrives in your channel. Once everything looks correct, click Activate to turn the workflow on. Every new Feedspace testimonial will now post a Slack notification automatically.
