You can create production applications with **FastAPI** right now (and you have probably been doing it for some time), you just have to make sure that you use a version that works correctly with the rest of your code.

## Pin your `fastapi` version { #pin-your-fastapi-version }

Just functions that look the same as the *path operation functions*.

But still, it is very powerful, and allows you to declare arbitrarily deeply nested dependency "graphs" (trees).

/// tip

All this might not seem as useful with these simple examples.

But you will see how useful it is in the chapters about **security**.

And you will also see the amounts of code it will save you.

### Tags with Enums { #tags-with-enums }

If you have a big application, you might end up accumulating **several tags**, and you would want to make sure you always use the **same tag** for related *path operations*.

In these cases, it could make sense to store the tags in an `Enum`.

						<div class="col-sm-6">
							<h1>
								<la:message key="labels.storage_configuration" />
							</h1>
						</div>
						<div class="col-sm-6">
							<ol class="breadcrumb float-sm-right">
								<li class="breadcrumb-item"><la:link href="/admin/storage/">
										<la:message key="labels.crud_link_list" />
									</la:link></li>

## In summary

We welcome AI-assisted contributions from people who understand what they're submitting and are ready to collaborate on it.

We reserve the right to close PRs and restrict future contributions from submitters who repeatedly violate this policy, submit low-effort AI-generated content, or fail to engage meaningfully in the review process. 

This can make it a lot easier for your users to **implement their APIs** to receive your **webhook** requests, they might even be able to autogenerate some of their own API code.

Webhooks are available in OpenAPI 3.1.0 and above, supported by FastAPI `0.99.0` and above.

 * <p>A min-max priority queue can be configured with a maximum size. If so, each time the size of
 * the queue exceeds that value, the queue automatically removes its greatest element according to
 * its comparator (which might be the element that was just added). This is different from
 * conventional bounded queues, which either block or reject new elements when full.
