<p>Idempotence is a funky word that often hooks people. Idempotence is sometimes a confusing concept, at least from the academic definition.</p>
|
|
<p>Turns out, with respect to a REST API, idempotency just means that you can make one call to an API or many calls to that API and have the same end result. For instance, calling update (via PUT, say) with the same data will result in the same data being stored on the server.</p>
|
|
<p>That‚s all there is to it. Watch the video to take a humorous deeper-look at idempotence.</p>
