You can use our sandbox environment to fully test the webhook functionality and analyze the callback data sent by OxaPay. It allows you to simulate transactions and verify that your system is properly handling the callbacks we send.
If you're not receiving callbacks, there could be several reasons for this — one common issue is not whitelisting OxaPay’s IP addresses on your server. You can obtain these IP addresses from our support team.
Other possible causes include incorrect webhook configurations on your end. If you're unsure or need help, feel free to contact our support team — our agents will gladly assist you with troubleshooting and setup.
