#Use iDiagnose

iDiagnose helps developers locate problems quickly during integration testing, and makes corresponding changes according to the suggestions provided by the system during troubleshooting. For example, if you input a currency that is not supported by the business, iDiagnose locates the incorrect currency field and recommends a supported one. This helps developers to self-troubleshoot effectively.


Currently, you can only search for transactions from the last seven days. iDiagnose supports the troubleshooting of sandbox and production environments. The developer can set the environment manually and input a specific payment request ID to query detailed issues throughout its entire payment journey. This helps developers better understand specific problems that occur during integration tests.
