Im currently working with Radixx ConnectPoint (connectpoint.radixx.com/sdk/) - have integrated the full API, everything works fine while suddenly at times the agent account being used locks out. After that the login request fails. No errors before the lock out from the API. No rate limits defined in the documentation. No warnings. Im unable to reach their technical support. I have assessed the basic issues including making sure the password is correctly used in the request (shows in the logs) and is only used in this one place. Have been unable to see any pattern to the lock outs.<p>What options do I have in terms of debugging the problem? What are the technical approaches for debugging an external api whose implementation details you have no idea about?
