## 8.2.1. Versioning

1
The User API service exposes one or more versions of the User protocol. The service uses the verdant protocol to advertise which versions of the User protocol are available. Executing a GET request to the root endpoint will yield a verdant message showing which versions of the User protocol are available. The User protocol is assigned the protocol identifier ed628c5a-0182-36ab-bee3-5fe6f6a21894.
2
As an example, the following shows that the User protocol version 1 is available at /user/1/0/:

### 8.2.1.3. Verdant Example

    $ curl https://idstore.example.com:50000/ | hexdump
    0000:0000 | 00 00 00 01  00 00 00 01  ED 62 8C 5A  01 82 36 AB | ........íb.Z..6«
    0000:0010 | BE E3 5F E6  F6 A2 18 94  00 00 00 01  00 00 00 00 | ¾ã_æö¢..........
    0000:0020 | 00 00 00 0A  2F 75 73 65  72 2F 31 2F  30 2F       | ..../user/1/0/

## 8.2.2. Health

1
The User API service exposes a health check endpoint at /health. The endpoint returns a 200 status code and the string OK if the server's most recent internal health checks succeeded. The server returns a 500 status code and string not equal to OK if the server's most recent internal health checks failed. In both cases, the string is returned directly as a text/plain UTF-8 value.

## 8.2.3. Version 1.0

## 8.2.3.1. Encoding

1
The version 1 User protocol uses cedarbridge encoded messages over HTTP(s).

## 8.2.3.2. Login

1
Send an IdU1CommandLogin command to /user/1/0/login. If the login succeeds, a cookie named IDSTORE_USER_API_SESSION will be set. This cookie must be included with all subsequent requests.

## 8.2.3.3. Commands

1
After logging in successfully, send commands of type IdU1Command* to /user/1/0/command. Failed commands will yield a value of type IdU1ResponseError, whilst successful results will yield values of type IdU1Response*.

## 8.2.3.4. Generated Documentation

1
Generated documentation for the Cedarbridge schemas is available:
