SPIn Proxy (Troubleshooting)
SPIn proxy helps integrators ensure the connection is established between SPIn and the payment terminal.
- Login to iPOSpays
- Click “Troubleshooting SPIn Proxy”
- Enter your TPN
- Click “Check POS Connection”
If the arrow between the SPIn logo and the payment terminal logo is lit up in green, it indicates that the connection has been successfully established. If the arrow is lit up in red, it means the connection has not been established and there is an issue. In this case, please reach out to us at support@dejavoosystems.com.
We also offer simulated testing to verify if the generated Auth Key and TPN are working and ready to be configured with the Host System.
TPN & Auth Key Check – Short Steps:
