I have been testing with this example in php [Cannot retrieve my Access Token](https://integration.keap.com/t/cannot-retrieve-my-access-token/1013), but I have not been able to receive my access token. According to [Get Started - Keap Developer Portal](https://developer.infusionsoft.com/get-started/) , is it a must to have a sandbox account? since I have not created it.
