## REST API call to plugin

To verify the custom token presented in the `AssumeRoleWithCustomToken` API, MinIO makes a POST request to the configured identity management plugin endpoint and expects a response with some details as shown below:

### Request `POST` to plugin endpoint

Query parameters:

| Parameter Name | Value Type | Purpose                                                                 |

  )

  fun toDer(value: T): ByteString {
    val buffer = Buffer()
    val writer = DerWriter(buffer)
    toDer(writer, value)
    return buffer.readByteString()
  }

  /**

   * when a value has both a context or application tag and a universal tag.
   *
   * Use this for EXPLICIT tag types:

	flag.StringVar(&path, "path", "", "path name where the attribute shall be applied")
	flag.StringVar(&name, "name", "", "attribute name or it can be a wildcard if '.' is specified")
	flag.Uint64Var(&value, "value", 0, "attribute value expects the value to be uint64")
	flag.BoolVar(&set, "set", false, "this is a set attribute operation")

	flag.Parse()

	if set && value == 0 {
		log.Fatalln("setting an attribute requires a non-zero value")
	}

It is not very popular or used nowadays.

OAuth2 doesn't specify how to encrypt the communication, it expects you to have your application served with HTTPS.

/// tip

In the section about **deployment** you will see how to set up HTTPS for free, using Traefik and Let's Encrypt.

When configured, MinIO sends request and credential details for every API call to an external HTTP(S) endpoint and expects an allow/deny response. MinIO is thus able to delegate access management to an external system, and users are able to use a custom solution instead of S3 standard IAM policies.
