Deep Dive: Designing the OpenClaw Plugin Rating API

Answer: The OpenClaw Plugin Rating API is a versioned, token‑based REST interface that lets developers submit, update, and query rating data for plugins using well‑defined JSON request and response schemas.

Deep Dive: Designing the OpenClaw Plugin Rating API

1. Introduction

OpenClaw’s ecosystem thrives on high‑quality plugins that extend core functionality. To maintain trust and encourage continuous improvement, the platform needs a reliable way to capture user sentiment. The Plugin Rating API fulfills this need by offering a clear contract for rating operations, supporting authentication, schema validation, and backward‑compatible versioning. This guide walks developers through every facet of the API—from authentication mechanics to best‑practice integration patterns—so you can embed rating capabilities with confidence.

2. API Overview

The API follows conventional REST principles and is hosted under the base URL:

https://api.openclaw.io/v1/plugins/{pluginId}/ratings

• Resource: /plugins/{pluginId}/ratings
• Methods: POST (create), GET (list), PUT (update), DELETE (remove)
• Content‑type: application/json
• Response format: JSON with standard HTTP status codes

3. Authentication

Security is enforced via Bearer Token authentication. Tokens are issued by OpenClaw’s OAuth2 server and must be included in the Authorization header of every request.

Authorization: Bearer <access_token>

Tokens have a default lifespan of 1 hour and can be refreshed using the standard /oauth/token endpoint. For server‑to‑server integrations, a client credentials grant is recommended.

4. Request Schema

All payloads must conform to the JSON schema below. The schema is deliberately MECE (Mutually Exclusive, Collectively Exhaustive) to avoid ambiguity.

Example POST payload:

{
  "rating": 4,
  "comment": "Great plugin, but could use better docs.",
  "metadata": {
    "os": "windows",
    "appVersion": "2.3.1"
  }
}

5. Response Schema

Successful responses return a 201 (Created) or 200 (OK) status with the persisted rating object, enriched with system‑generated fields.

Example GET response (list of ratings):

{
  "ratings": [
    {
      "id": "a1b2c3d4-5678-90ab-cdef-1234567890ab",
      "pluginId": "com.openclaw.analytics",
      "rating": 5,
      "comment": "Excellent integration!",
      "createdAt": "2024-03-12T08:45:30Z"
    },
    ...
  ],
  "page": 1,
  "pageSize": 20,
  "totalCount": 342
}

6. Versioning Strategy

To protect downstream applications, the API follows semantic versioning at the URL level. The current stable release is v1. Future breaking changes will be introduced under a new major segment (e.g., /v2/), while non‑breaking additions stay within the same major version.

• Path versioning: /v1/… ensures explicit client intent.
• Header deprecation: Responses include Deprecation and Sunset headers when an endpoint is slated for removal.
• Feature toggles: Optional fields are introduced as nullable to avoid immediate breakage.

Example of a deprecation header:

Deprecation: true
Sunset: Wed, 30 Sep 2025 00:00:00 GMT

7. Integration Best Practices

7.1. Idempotent Writes

Use the PUT /plugins/{pluginId}/ratings/{ratingId} endpoint for updates. Include the original id to guarantee idempotency, preventing duplicate records when retries occur.

7.2. Rate Limiting & Back‑off

OpenClaw enforces a default limit of 100 requests per minute per token. Implement exponential back‑off and respect the Retry-After header on 429 Too Many Requests responses.

7.3. Pagination & Caching

For bulk retrieval, always request paginated data using page and pageSize query parameters. Cache the ETag header and issue If-None-Match on subsequent calls to reduce bandwidth.

7.4. Validation & Error Handling

• 400 Bad Request – schema validation failure (e.g., rating outside 1‑5).
• 401 Unauthorized – missing or invalid token.
• 404 Not Found – plugin or rating ID does not exist.
• 422 Unprocessable Entity – business rule violation (e.g., duplicate rating from same user).

7.5. Observability

Emit structured logs that include requestId, pluginId, and statusCode. Correlate these logs with OpenClaw’s audit trail for compliance reporting.

7.6. Leveraging Existing UBOS Capabilities

If your plugin already runs on the UBOS platform overview, you can reuse its OAuth client configuration and benefit from built‑in rate‑limit dashboards. This reduces integration effort and aligns your authentication flow with other UBOS‑powered services.

7.7. Real‑World Example: ChatGPT‑Powered Rating Assistant

Combining the Plugin Rating API with the OpenAI ChatGPT integration enables a conversational rating assistant that prompts users for feedback and automatically posts it to OpenClaw. The flow is:

1. ChatGPT collects rating via a UI widget.
2. The widget sends a POST request to the Rating API using the stored bearer token.
3. On success, ChatGPT confirms receipt and displays the aggregated score.

8. Conclusion

The OpenClaw Plugin Rating API is a purpose‑built, versioned service that balances flexibility with strict contract enforcement. By adhering to the authentication model, respecting the JSON schemas, and following the integration best practices outlined above, developers can deliver reliable rating experiences that scale alongside the OpenClaw marketplace.
