Do we get a cash out delay value from the OTS? Or is this something we have to set ourselves?

The logic/engine of calculating the cashout options (based on the probability you get in our feed) is on your side; you just need to communicate to our OTS if a ticket was cashed out successfully. In some cases we can reject the ticket cashout as stated in the table Regarding the delay for cashing out – the standard is to give a user an offer based on probability (from our feed) and the user's ticket. This offer is valid until the probabilities change, when you are entitled to cancel or change the offer. Once the user hits "accept", you can apply some delay on your side in order to see if anything will change (odds/probability, bet stop...). The delay could be the same as our bet acceptance delay (default is 5 sec). We do not check if the odds/probability has changed for cashed-out tickets; we only check if the ticket was sent correctly.
