Duplicate_transaction

[ShootnikD]

Sometimes, when I tried to use function placeOrders or cancelOrders, I had receive DUPLICATE_TRANSACTION. After that error I tried send the same request and received good response. Why it happened? Api bag?

Are you trying to place multiple bets with the same customerRef?

From https://api.developer.betfair.com/se...ni/placeOrders

Optional parameter allowing the client to pass a unique string (up to 32 chars) that is used to de-dupe mistaken re-submissions.
