A comprehensive and **fully tested** PHP SDK for integrating with the CJ Affiliate (Commission Junction) API. Built with Guzzle HTTP client and tested with real CJ credentials to ensure 100% compatibility.

⚠️ Important Note About Product Search
--------------------------------------

[](#️-important-note-about-product-search)

**CJ Affiliate does not offer a public Product Search API.**

After extensive testing with real CJ credentials, we confirmed that:

- The GraphQL Product Search endpoint (`ads.api.cj.com/graphql`) does not exist (404 error)
- Product Feeds are for advertisers to submit products, not for publishers to query

**Solution:** Use the **Link Search API** instead. It returns affiliate links that include product information (names, URLs, commissions, etc.).

See [API\_CHANGES.md](API_CHANGES.md) for details.
