Idempotency - What it is and How to Implement it

It is important to understand idempotency if you are going to be building APIs that are open to the public. Idempotency is especially useful when you have operations that must only occur once like making in a payment. In this video I give an overview of what idempotency is, why we use it and how to implement it.
