End‑to‑End Integration Guide for the OpenClaw Rating API in Moltbook

Integrating OpenClaw Rating API with Moltbook – A Senior Engineer’s Playbook

In today’s AI‑agent frenzy, developers are racing to embed intelligent features directly into their products. One such capability is real‑time user rating collection, which can power recommendation engines, trust scores, and more. This guide walks you through a complete end‑to‑end integration of the OpenClaw Rating API within Moltbook, covering authentication, fetching ratings, UI display, submitting new ratings, and webhook handling.

1. Authentication

OpenClaw uses a simple API‑key scheme. Store your key securely (e.g., in an environment variable OPENCLAW_API_KEY) and include it in the Authorization header for every request:

Authorization: Bearer YOUR_API_KEY

2. Fetching Ratings

Use the /ratings endpoint to retrieve existing scores for a Moltbook item. Example request (Node‑RED function node):

const options = {
  method: "GET",
  url: "https://api.openclaw.io/ratings",
  qs: { itemId: msg.payload.itemId },
  headers: { Authorization: `Bearer ${process.env.OPENCLAW_API_KEY}` }
};
return fetch(options).then(res => res.json());

3. UI Display

Render the rating data using a lightweight star component. The component receives average and count props and updates reactively when the underlying data changes.

4. Submitting New Ratings

When a user rates an item, POST to /ratings with the payload { itemId, rating }. Ensure you validate the rating client‑side (1‑5) before sending.

5. Webhook Handling

Configure a webhook in the OpenClaw dashboard to POST to your Moltbook endpoint (e.g., /api/openclaw/webhook) whenever a rating is created or updated. Verify the webhook signature using the secret provided by OpenClaw to guard against spoofed calls.

6. Putting It All Together

Combine the above steps in a single Node‑RED flow: fetch → display → submit → listen for webhook → refresh UI. This pattern keeps the UI in sync without polling.

By following this guide, you’ll have a robust rating system that scales with your user base and leverages the latest AI‑agent hype to deliver smarter experiences.
