Connecting OpenClaw Rating API Edge Webhooks to Zapier for No‑Code Automation

Introduction

The OpenClaw Rating API provides real‑time rating
events (e.g., user reviews, star scores, sentiment tags) via Edge
Webhooks. For developers, product managers, and no‑code enthusiasts, the
biggest question is: How can these events be turned into actionable
workflows without writing a single line of code?

Zapier’s visual automation platform is the perfect bridge. By routing
OpenClaw’s webhook payloads into Zapier, you can instantly trigger Slack
notifications, generate Trello cards for follow‑up, or update a CRM record.

This tutorial walks you through every step—from configuring the webhook in
OpenClaw to building three production‑ready Zaps. The guide assumes a
basic familiarity with Zapier and OpenClaw’s dashboard, but no programming
experience is required.

Overview of OpenClaw Rating API Edge Webhooks

OpenClaw’s Edge Webhooks are lightweight HTTP POST callbacks that fire
whenever a rating event occurs on any of your integrated products. The
payload is a JSON object containing:

• rating_id – Unique identifier for the rating.
• user_id – Identifier of the user who submitted the rating.
• score – Numeric rating (1‑5).
• comment – Optional free‑text comment.
• timestamp – ISO‑8601 UTC timestamp.
• metadata – Custom key/value pairs you define in OpenClaw.

Because the webhook is executed at the network edge, latency is under
100 ms, making it ideal for real‑time notifications and downstream data
pipelines.

Setting Up the Custom Webhook in OpenClaw

1. Log in to the OpenClaw dashboard. Navigate to Integrations → Webhooks.
2. Click “Add New Webhook”. Choose Rating Event as the trigger type.
3. Enter the Zapier webhook URL. You will generate this URL in the next section, but for now you can paste a placeholder (e.g., https://hooks.zapier.com/hooks/catch/123456/abcdef/).
4. Configure payload format. Select JSON and enable Include Metadata if you need custom fields.
5. Save the webhook. OpenClaw will now send a test POST to the URL you provided.

Tip: Keep the webhook URL handy; you will need it when you
create the Zapier “Catch Hook” trigger.

Connecting the Webhook to Zapier

Zapier’s Webhooks by Zapier app provides a “Catch Hook” trigger that
listens for incoming POST requests. Follow these steps to wire the two
services together:

1. Create a new Zap. In Zapier, click Make a Zap.
2. Choose “Webhooks by Zapier” → “Catch Hook”. Zapier will generate a unique URL.

   https://hooks.zapier.com/hooks/catch/987654/xyz123/

3. Copy the URL. Return to the OpenClaw webhook configuration
   (step 4 above) and replace the placeholder with this URL. Click Save.
4. Send a test payload. In OpenClaw, click Send Test.
   Zapier will capture the JSON and display it in the “Test Trigger” screen.
5. Review the captured data. Verify that fields like
   rating_id, score, and comment appear.
   Click Continue to move to the Action step.

At this point the webhook‑to‑Zapier pipeline is live. Any new rating in
OpenClaw will instantly fire the Zap.

Example Zap: Posting Rating Events to Slack

Sending a concise Slack message for each rating helps support teams react
quickly. Below is a step‑by‑step configuration.

Action Setup

1. App & Event: Choose Slack → Send Channel Message.
2. Connect your Slack workspace. Authorize Zapier if you haven’t already.
3. Customize Message: Use Zapier’s field mapper to insert
   webhook data.

   {
     "channel": "#ratings",
     "text": "*New rating received!* :star: *Score:* {{score}} / 5\n*User:* {{user_id}}\n*Comment:* {{comment}}\n*Time:* {{timestamp}}"
   }

   The double curly braces (e.g., {{score}}) pull values from the
   webhook payload.

4. Test the Action. Zapier will post a sample message to the
   selected Slack channel. Verify formatting and adjust as needed.
5. Turn on the Zap. Once satisfied, give the Zap a name like
   “OpenClaw → Slack Rating Alerts” and enable it.

Result: Every time a user rates a product, a nicely
formatted Slack notification appears, allowing your team to acknowledge
positive feedback or address negative sentiment instantly.

Example Zap: Creating Trello Cards from Ratings

Turning low‑scoring ratings into Trello cards ensures that product owners
have a visual backlog of issues to resolve.

Action Setup

1. App & Event: Choose Trello → Create Card.
2. Connect Trello. Authorize Zapier to access your boards.
3. Board & List: Select the board (e.g., “Product Feedback”) and the list (e.g., “To‑Do”).
4. Card Title & Description: Map fields from the webhook.

   Title: "Rating {{rating_id}} – {{score}}★"
   Description: "User {{user_id}} left a comment:\n{{comment}}\n\nTimestamp: {{timestamp}}"
   

5. Labeling (optional): Add a red label when score <= 2 using a Zapier filter step before the Trello action.
6. Test & Activate. Zapier will create a test card; verify that the data appears correctly, then turn the Zap on.

Result: Every rating of 2 stars or lower automatically spawns a Trello card, giving product teams a clear, prioritized view of issues.

Example Zap: Updating a CRM with Rating Data

Keeping your CRM (e.g., HubSpot, Salesforce) in sync with user sentiment
helps sales and support teams personalize outreach.

Action Setup (HubSpot example)

1. App & Event: Choose HubSpot → Update Contact.
2. Connect HubSpot. Authorize Zapier to read/write contacts.
3. Search Contact: Use the user_id from the webhook to find the matching contact (Zapier’s “Find Contact” step).
4. Update Fields: Map rating data to custom properties.

   Property: "latest_rating_score" → {{score}}
   Property: "latest_rating_comment" → {{comment}}
   Property: "last_rating_timestamp" → {{timestamp}}
   

5. Conditional Logic (optional): Add a Filter step so the Zap only runs for scores ≤ 3, ensuring only concerning feedback updates the CRM.
6. Test & Deploy. Verify that the contact’s custom fields are updated, then enable the Zap.

Result: Your CRM now reflects the most recent rating for each user, enabling data‑driven outreach and churn prevention.

Testing and Troubleshooting

Even the most carefully built webhook‑to‑Zap pipelines can encounter hiccups.
Below is a checklist to ensure smooth operation.

1. Verify Webhook Delivery

• In OpenClaw, open the webhook’s History tab. Look for HTTP 200 responses.
• Check Zapier’s Task History for “Catch Hook” events. A green checkmark means the payload was received.

2. Inspect Payload Structure

• Use a tool like Webhook.site to view raw JSON if you suspect formatting issues.
• Ensure field names match exactly (e.g., score vs. ratingScore).

3. Common Error Scenarios

4. Use Zapier’s “Replay” Feature

If a specific rating event failed, locate it in Zapier’s task history and click “Replay”. This re‑sends the same payload through the Zap, allowing you to test fixes without generating a new rating.

5. Monitoring & Alerts

Set up a secondary Zap that watches Zapier’s “Zap Runs” and sends an email if a task fails more than three times in an hour. This proactive alert prevents silent data loss.

Conclusion and Next Steps

By following this tutorial you have turned raw rating events from the
OpenClaw Rating API into actionable, no‑code workflows across Slack,
Trello, and your CRM. The same pattern can be extended to dozens of
Zapier‑compatible apps—think Google Sheets for analytics, Airtable for
reporting, or even a custom email digest.

For teams that need higher reliability, consider hosting OpenClaw on a
dedicated environment. OpenClaw hosting on UBOS provides managed scaling, built‑in SSL, and automatic webhook retries.

Keep experimenting:

• Combine multiple rating fields into a single Slack thread for grouped alerts.
• Use Zapier’s “Formatter” to convert timestamps into your local timezone.
• Trigger a “Send SMS” action for critical low‑score ratings using Twilio.

The power of Edge Webhooks plus Zapier’s visual builder means you can iterate
faster than ever—no code, no deployment bottlenecks, just pure automation.
