Thanks - will investigate that endpoint and get back to you if I have any questions!
One broad question regarding the points: I see that in the payment types at checkout, there is a credit_balance field. Am I correct in assuming that the flow for redeeming points is then as described below?
1) via the /api/prizes endpoint, turn the points into a credit balance
2) receive some kind of id for this balance[?]
3) pass this id and the value of the balance as part of the payments array at checkout under the credit_balance field
