Safaricom mpesa payment gateway

What could the cause of server error when you register callback urls on powerlynx payment gateway configuration

Hello,

One of the main issues you might encounter when registering callback URLs for Safaricom MPESA in Powerlynx is using incorrect credentials. We strongly advise reaching out to MPESA support to confirm the credentials that should be used in Powerlynx.

Additionally, at times, our clients face difficulty when attempting to connect the MPESA sandbox account to Powerlynx due to an error that prevents the registration of URLs.

"errorCode": "500.003.1001",
"errorMessage": "Service is temporarily not available.Please try again later."

The issue can also be resolved with the help of MPESA support.
