Problem with PlaceOrders request

[ians1711]

Developing a new program. Have successfully got most read-only requests working. Final piece of code to debug is the PlaceOrders request. Currently get a 400 - Bad Request from the server for the following params:

{"marketId":"1.176181490","instructions":[{"orderType":0,"selectionId":1,"handicap":0.0,"sid e":1,"limitOrder":{"size":2.0,"price":1.01,"persis tenceType":1},"limitOnCloseOrder":null,"marketOnCl oseOrder":null}]}

Can't see any more information in the HTTP response (but should I anyway?). Have compared this params string with what the API visualizer generates and can't see any difference. Any ideas what could be wrong??

Thanks in advance

Is this what you actually sent? orderType 0? persistenceType 1?

I'm dumping the output from the Newtonsoft call to JsonConvert.SerializeObject. These should be the ENUM values for OrderType.LIMIT and PersistenceType.PERSIST. Both these options were accepted by the API Visualiser?

This is what the API visualiser sends - the only difference I can see is the ENUM values have been replaced by text values.
Request data: [{"jsonrpc": "2.0", "method": "SportsAPING/v1.0/placeOrders", "params": {"marketId":"1.176181490","instructions":[{"selectionId":"1","handicap":"0","side":"LAY", "or derType":"LIMIT","limitOrder":{"size":"2","price": "1.01","persistenceType":"PERSIST"}}]}, "id": 1}]

I think I have worked it out - had missed the following:
