## Pin your `fastapi` version

The first thing you should do is to "pin" the version of **FastAPI** you are using to the specific latest version that you know works correctly for your application.

For example, let's say you are using version `0.45.0` in your app.

If you use a `requirements.txt` file you could specify the version with:

```txt
fastapi==0.45.0
```

| [**WebIdentity**](https://github.com/minio/minio/blob/master/docs/sts/web-identity.md) | Let users request temporary credentials using any OpenID(OIDC) compatible web identity providers such as KeyCloak, Dex, Facebook, Google etc. |

## An app with callbacks

Let's see all this with an example.

Imagine you develop an app that allows creating invoices.

These invoices will have an `id`, `title` (optional), `customer`, and `total`.

The user of your API (an external developer) will create an invoice in your API with a POST request.

Then your API will (let's imagine):

    abstract val propertiesFile: RegularFileProperty

    @get:Internal
    abstract val compatibilityDocFile: RegularFileProperty

    @TaskAction
    fun fetch() =
        fetchLatestAgpVersions().let { fetchedVersions ->
            updateProperties(fetchedVersions)
            updateCompatibilityDoc(fetchedVersions.latests)
        }

    private

**FastAPI** provides several tools to help you deal with **Security** easily, rapidly, in a standard way, without having to study and learn all the security specifications.

But first, let's check some small concepts.

## In a hurry?

If you don't care about any of these terms and you just need to add security with authentication based on username and password *right now*, skip to the next chapters.
