Travelport Universal API confirm air booking Agent ID exception

Question

I am working on a travel agency website in MVC4 which is using travelport for flight inquiries, pricing and booking. It working fine untill i proceed to confirm air booking. It's throwing this exception

Message From Galileo : Uncaught Service Exception cause:com.cendant.tds.soa.framework.ServiceException: Exception ReturnedERR: AGENT ID - GALILEO
|+With the Dynamic GTID list of:AF86B8 

This is the agent information that i am setting in my request

AgentAction agentaction = new AgentAction()
{
    ActionType = AgentActionActionType.Created,
    AgentCode = "My Agent Code",
    BranchCode = "My Branch Code",
    AgencyCode = "My Agency Code",
    EventTime = DateTime.Now
};

Also tried to set AgentIDOverride but still getting that same exception. Can anyone guide me how to solve this problem? Thanks in advance

Answer 1

There was some issue with my credentials, after generating the test credentials i was able to perform the request. Apparently my original credentials were inactive which was resulting in this exception which was solved. I know this is late but might be helpful for someone.
