## 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.

Introduction

To enable the integration of custom authentication methods, MinIO can be configured with an Identity Management Plugin webhook. When configured, this plugin enables the `AssumeRoleWithCustomToken` STS API extension. A user or application can now present a token to the `AssumeRoleWithCustomToken` API, and MinIO verifies this token by sending it to the Identity Management Plugin webhook. This plugin responds with some information and MinIO is able to generate temporary STS credentials...
