Versioning and Upgrading the OpenClaw Rating API: A Developer’s Guide

Direct Answer

The OpenClaw Rating API can be versioned and upgraded safely by adopting semantic versioning, publishing clear deprecation policies, providing migration checklists, and using UBOS‑provided CLI tools and automated scripts to validate compatibility before you push changes to production.

1. Introduction

This developer‑focused guide explains best‑practice versioning strategies, migration paths, backward‑compatibility guarantees, and upgrade tooling for the OpenClaw Rating API. Whether you are building a brand‑new review system or maintaining an existing integration, the steps below will help you avoid breaking changes and keep your users happy.

Audience: API developers, technical leads, and integration engineers who need to implement, maintain, or upgrade the OpenClaw rating & review system in SaaS products, marketplaces, or internal tools.

2. Understanding API Versioning

2.1 Semantic versioning basics

Semantic versioning (semver.org) uses a three‑part number MAJOR.MINOR.PATCH:

• MAJOR – breaking changes that require client code updates.
• MINOR – backward‑compatible feature additions.
• PATCH – backward‑compatible bug fixes.

2.2 Versioning models

There are three common ways to expose a version to callers:

For the OpenClaw Rating API we recommend URL versioning because it aligns with RESTful best practices and works out‑of‑the‑box with most load balancers and CDNs.

3. Best‑Practice Versioning Strategies for OpenClaw Rating API

3.1 Stable vs. experimental endpoints

Separate stable (v1, v2) from experimental (beta) routes. Use the /beta/ prefix for features that may change before they graduate to a stable version.

3.2 Deprecation policy

Our policy follows a three‑stage lifecycle:

1. Announcement – publish a deprecation notice 90 days before removal.
2. Grace period – keep the old endpoint functional but return a Warning header.
3. Removal – after the grace period, the endpoint returns 410 Gone.

All deprecation notices are posted on the UBOS platform overview and included in the OpenClaw changelog.

3.3 Documentation practices

Maintain a version‑specific Swagger/OpenAPI spec and host it under /docs/vX/. Include:

• Change logs for each release.
• Migration guides (see Section 4).
• Sample request/response payloads.

4. Migration Paths

4.1 Step‑by‑step migration checklist

4.2 Handling breaking changes

When a MAJOR version bump introduces breaking changes:

• Introduce a v2 namespace while keeping v1 alive.
• Provide a /v1/convert endpoint that translates old payloads to the new schema.
• Offer SDK updates (e.g., AI Chatbot template) that abstract version differences.

4.3 Version negotiation examples

// Example: Node.js fetch with URL versioning
fetch('https://api.yourapp.com/v2/ratings', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ productId: 123, score: 4.5 })
})
  .then(res => res.json())
  .then(data => console.log('Rating saved:', data));

5. Backward‑Compatibility Guarantees

5.1 Contract testing

Use Workflow automation studio to generate Pact contracts for each endpoint. Contracts are stored in the contracts/ folder and validated on every CI run.

5.2 Compatibility matrix

5.3 Support windows

After a MAJOR version is released, we guarantee support for the previous MAJOR version for at least 18 months. Critical security patches are back‑ported for the entire support window.

6. Upgrade Tooling

6.1 CLI tools for version checks

The ubos-cli includes a version-check command that scans your codebase for deprecated endpoints and suggests replacements.

# Run version check
ubos-cli version-check --api=openclaw --target=v2

# Sample output
[WARN] /v1/ratings is deprecated – use /v2/ratings instead.
[INFO] All other endpoints are up‑to‑date.

6.2 Automated migration scripts

UBOS ships a set of migration‑scripts/ that perform bulk JSON transformations. Example for moving from ratingText to comment:

# migrate-rating.js
const fs = require('fs');
const data = JSON.parse(fs.readFileSync('ratings.json'));

data.forEach(r => {
  r.comment = r.ratingText;
  delete r.ratingText;
});

fs.writeFileSync('ratings_v2.json', JSON.stringify(data, null, 2));

6.3 Testing frameworks

Integrate Web app editor on UBOS with Jest or PyTest to run contract‑driven tests automatically after each migration.

7. Real‑World Example: Upgrading from v1.x to v2.0

Below is a concise walkthrough of a typical upgrade performed by a SaaS startup using the OpenClaw Rating API.

7.1 Initial state (v1.x)

// v1 request payload
{
  "productId": 987,
  "rating": 5,
  "ratingText": "Excellent product!"
}

7.2 Target state (v2.0)

// v2 request payload
{
  "productId": 987,
  "score": 5,
  "comment": "Excellent product!"
}

7.3 Migration steps

1. Run ubos-cli version-check --target=v2 to locate ratingText usage.
2. Execute the provided migrate-rating.js script to rename the field.
3. Update endpoint URLs from /v1/ratings to /v2/ratings.
4. Run the contract test suite via npm test. All tests pass.
5. Deploy the new version to a blue‑green environment and monitor the /health endpoint.

7.4 Common pitfalls & how to avoid them

• Hard‑coded URLs: Use environment variables or the UBOS partner program config service to inject the version prefix.
• Missing fields: The compatibility matrix (Section 5) shows which fields are mandatory in v2.
• Cache stale data: Invalidate CDN caches after the deployment.

8. Conclusion

By following semantic versioning, publishing clear deprecation notices, leveraging UBOS’s migration tooling, and running contract‑driven tests, you can upgrade the OpenClaw Rating API with confidence. The process is repeatable, auditable, and fully supported by the UBOS homepage.
