Can't place bets with delayed app key.

[Conor]

I'm using the delayed key and I've been told I can still place bets, however I've tried lots of things and it's starting to get very frustrating..
I get the following response when calling a post to https://api.betfair.com/exchange/bet...0/placeOrders/ { "faultcode": "Client", "faultstring": "ANGX-0015", "detail": { "APINGException": { "requestUUID": "ie2-ang15b-prd-09051117-0099ba6943", "errorCode": "ACCESS_DENIED", "errorDetails": "" }, "exceptionname": "APINGException" } } How do I get someone to unlock this feature for me? Thanks

And that is the right I think. This is just for testing api, you must have live app key, buy one.
