Sage 50 – US Edition
Why am I receiving a server error on every login attempt in Payment Center?
Verify the MID/MKEY entered in Sage 50 matches with an existing Paya Exchange Virtual Terminal (the VT within Sageexchange.com).
Also, to access the Online Payment Center, remember to use the same credentials you would use to log into your SageExchange.com account. If the issue persists, please contact our Support Team by dialing 1-877-470-4001.
If you have questions or require additional information, please submit a ticket and we will be in touch with you shortly.
