Any one have knowledge regarding system one (TPP)

I am working in System one (TPP) in which i configure soap API call but it throw certificate error. i already generated certificate and submit. but not sure how to pass that certificate while calling API of system one

I assume if you’re working with certificates then you’re working with the server api instead of the client api ?
Are you using the test harness that is provided by the integration partners team to make sure you’re inputting all the correct endpoints/password/versions etc?

I found the error messages to be less than useful when trying to work with the server API, so I ended up just working with the client API to get data sent … Sorry not to be able to help but I’ll also be watching this thread!
