Introduction

The Agent Proxy client is exposing a REST API for the maintenance of the forwarding services. The port is configured with the '[client.api] port' parameter.

Below are the available endpoints and examples of requests and responses.

Authentication

Only one set of credentials is supported for the REST API. It is configured under the [client.api] section with the user and password parameters

[client.api]
# UDMG Agent Client Admin API
port="2280"
# API basic authentication credentials, no default
username = "api_user"
password = "api_password"

The authentication of REST requests is done using basic HTTP authentication.

This authentication scheme is done using the HTTP Authorization header. To authenticate, the client must:

Step 1	Obtain user login and password.
Step 2	Build the user ID by concatenating the login, a colon (“:”) character ,and the password.
Step 3	Encode the obtained identifier in Base64.
Step 4	Prefix the encoded identifier with a declaration of the basic authentication scheme (“Basic”).

For example, if the user enters the name "Aladdin" and the password "open sesame", then the client must send the following header:

Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==

If the authentication of a request fails, the server will respond with an HTTP code .401 - Unauthorized
