On setting up the plugin, the MinIO server prints the Role ARN to its log. The Role ARN is generated by default based on the given plugin URL. To avoid this and use a configurable value set a unique role ID via `MINIO_IDENTITY_PLUGIN_ROLE_ID`.

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

## API Request

To make an STS API request with this method, send a POST request to the MinIO endpoint with following query parameters:

```

Note: In the case of S3, it is possible to create a tier from MinIO running in EC2 to S3 using AWS role attached to EC2 as credentials instead of accesskey/secretkey:

```
mc admin tier add s3 source S3TIER --bucket s3bucket --prefix testprefix/ --use-aws-role
```
