Troubleshooting API calls in the dev environment

[kentcooper]

Is there any way to troubleshoot why an API call is failing? I've been attempting everything I can think of to make a successful call to https://cert.api.fiservapps.com/ch/payments-vas/v1/security/credentials but I constantly get the response below no matter what I try and I have no idea how to tell why the call is bad.

{
"gatewayResponse": {
"transactionProcessingDetails": {
"apiTraceId": "0e43129eee6b4477a357724f0aaba0ee",
"clientRequestId": "3bee3f58-3ee8-4e31-a4e3-f4612483d70b"
}
},
"error": [
{
"type": "APIM",
"message": "Bad request."
}
]
}

Did you ever figure this out?
