The wwJsonSerializer instance that is used to serialize the outgoing and incoming data. This property is set on initialization and available for customization so you can set things like oSerializer.PropertyNameOverrides for example.

You can override oSerializer any time before CallService() is called by either directly setting the oSerializer property or by calling CreateSerializer().

loClient = CREATEOBJECT("wwJsonServiceClient")

loClient.oSerializer.PropertyNameOVerrides = "firstName,lastName,lastAccess"
loClient.oHttp.AddHeader("Authorization", lcBearerToken)

loClient.CallService(...)

o.oSerializer
