Hello @Matt_Clairmont,

This is a great answer to your question:

> [@When to use PUT versus POST?](https://discuss.elastic.co/t/when-to-use-put-versus-post/68550/2):
>
> It's all about REST semantics. POST basically that you are posting a request which is going to modify the server state. POST index/type { "foo": "bar" } will generate an \_id server side and will index the document with this \_id. PUT is used to send a resource to the server. PUT index/type/id { "foo": "bar" } will put or update a document named index/type/id in the server. Makes sense? More details here: [https://en.wikipedia.org/wiki/Representational\_state\_transfer](https://en.wikipedia.org/wiki/Representational_state_transfer)

- POST: auto-generation of ids
- PUT: specify an id
