Hi
We are testing the generic API. We would like to pass data to contextstore by using ExtraData:
Sample JSON:
{"identifier":"emailAddress","lastName":"Pale","destinationAddress":"testDestinationAddress","contactID":"Contact1234","extraData":"extraData:mytestExtraData","isUseRPAsCalledParty":"true","priority":"1","firstName":"Jack","emailAddress":"enda@edtest1.com","routePoint":"SystemDefaultDigitalRoutepoint","overwriteContextDetails":"false","ssoToken":"eyJhbGciOiJSUzI1...","workRequestID":"MyContextID"}

May I know what is the format if I would like to add more key,value in extradata?
for example:extraData":"extraData:mytestExtraData,custid:12345678--> Is it correct?
