🛠️ Technical Support

Thank you for visiting the KICC Developer Center. We provide prompt assistance for technical issues or errors encountered during the integration of EasyPAY and EasyCheck.

💡 Wait! Check this before inquiring

Most integration issues can be resolved immediately through the following documents. Checking these first can reduce your waiting time.

1. Error Code Lookup: Search for the received error code (resCd) to find the cause and resolution.
2. FAQ: Common questions regarding firewall settings, test account information, etc., are collected here.
3. Sandbox Testing: Test in the sandbox environment first to determine if the issue lies within your code or the server.
