Hi @JDream, can you confirm that you enabled guest access and provided GET access to the guest role for your mysqllocal_phptutorial service? Because otherwise you will need to authenticate.
What response or error is returned to your call as it is now? E.g., what’s the response to the same call ( GET http://localhost:80/rest/mysqllocal_phptutorial/customers?app_name=DF_EXPLORE ) from a browser or cURL?
