# GraphQL { #graphql }

As **FastAPI** is based on the **ASGI** standard, it's very easy to integrate any **GraphQL** library also compatible with ASGI.

You can combine normal FastAPI *path operations* with GraphQL on the same application.

/// tip

**GraphQL** solves some very specific use cases.

It has **advantages** and **disadvantages** when compared to common **web APIs**.

And similarly for ReDoc...

{* ../../docs_src/custom_docs_ui/tutorial001.py hl[2:6,11:19,22:24,27:33] *}

/// tip

The *path operation* for `swagger_ui_redirect` is a helper for when you use OAuth2.

If you integrate your API with an OAuth2 provider, you will be able to authenticate and come back to the API docs with the acquired credentials. And interact with it using the real OAuth2 authentication.

# AssumeRoleWithCustomToken [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

## Introduction

To integrate with custom authentication methods using the [Identity Management Plugin](../iam/identity-management-plugin.md)), MinIO provides an STS API extension called `AssumeRoleWithCustomToken`.

After configuring the plugin, use the generated Role ARN with `AssumeRoleWithCustomToken` to get temporary credentials to access object storage.

It is designed to be very simple to use, and to make it very easy for any developer to integrate other components with **FastAPI**.

## What is "Dependency Injection" { #what-is-dependency-injection }

All the security utilities that integrate with OpenAPI (and the automatic API docs) inherit from `SecurityBase`, that's how **FastAPI** can know how to integrate them in OpenAPI.

    private static DirectoryLeaseManager getDirectoryLeaseManager(SmbTreeHandleImpl th) {
        try {
            // For now, return null since we need to integrate with the session properly
            // This will be implemented when the session integration is complete
            log.debug("Directory lease manager integration not yet complete");
            return null;

But keep in mind that, as everything is handled in memory, in a single list, it will only work while the process is running, and will only work with a single process.

Adopt and use an open standard for API specifications, instead of a custom schema.
