Sven Dowideit ada86fc5b7 Looking into some broken links, I noticed that we don't need to use

relative paths, and also fixed some broken images.

There are still more todo - next PR I think :)

docker.io OAuth API

1. Brief introduction

Some docker.io API requests will require an access token to authenticate. To get an access token for a user, that user must first grant your application access to their docker.io account. In order for them to grant your application access you must first register your application.

Before continuing, we encourage you to familiarize yourself with The OAuth 2.0 Authorization Framework.

Also note that all OAuth interactions must take place over https connections

2. Register Your Application

You will need to register your application with docker.io before users will be able to grant your application access to their account information. We are currently only allowing applications selectively. To request registration of your application send an email to support-accounts@docker.com with the following information:

The name of your application
A description of your application and the service it will provide to docker.io users.
A callback URI that we will use for redirecting authorization requests to your application. These are used in the step of getting an Authorization Code. The domain name of the callback URI will be visible to the user when they are requested to authorize your application.

When your application is approved you will receive a response from the docker.io team with your client_id and client_secret which your application will use in the steps of getting an Authorization Code and getting an Access Token.

3. Endpoints

3.1 Get an Authorization Code

Once You have registered you are ready to start integrating docker.io accounts into your application! The process is usually started by a user following a link in your application to an OAuth Authorization endpoint.

GET /api/v1.1/o/authorize/

Request that a docker.io user authorize your application. If the user is not already logged in, they will be prompted to login. The user is then presented with a form to authorize your application for the requested access scope. On submission, the user will be redirected to the specified redirect_uri with an Authorization Code.

Query Parameters:

 

-   **client_id** – The `client_id` given to
    your application at registration.
-   **response_type** – MUST be set to `code`.
    This specifies that you would like an Authorization Code
    returned.
-   **redirect_uri** – The URI to redirect back to after the user
    has authorized your application. If omitted, the first of your
    registered `response_uris` is used. If
    included, it must be one of the URIs which were submitted when
    registering your application.
-   **scope** – The extent of access permissions you are requesting.
    Currently, the scope options are `profile_read`, `profile_write`,
    `email_read`, and `email_write`. Scopes must be separated by a space. If omitted, the
    default scopes `profile_read email_read` are
    used.
-   **state** – (Recommended) Used by your application to maintain
    state between the authorization request and callback to protect
    against CSRF attacks.

**Example Request**

Asking the user for authorization.

    GET /api/v1.1/o/authorize/?client_id=TestClientID&response_type=code&redirect_uri=https%3A//my.app/auth_complete/&scope=profile_read%20email_read&state=abc123 HTTP/1.1
    Host: www.docker.io

**Authorization Page**

When the user follows a link, making the above GET request, they
will be asked to login to their docker.io account if they are not
already and then be presented with the following authorization
prompt which asks the user to authorize your application with a
description of the requested scopes.

![](/reference/api/_static/io_oauth_authorization_page.png)

Once the user allows or denies your Authorization Request the user
will be redirected back to your application. Included in that
request will be the following query parameters:

`code`
:   The Authorization code generated by the docker.io authorization
    server. Present it again to request an Access Token. This code
    expires in 60 seconds.
`state`
:   If the `state` parameter was present in the
    authorization request this will be the exact value received from
    that request.
`error`
:   An error message in the event of the user denying the
    authorization or some other kind of error with the request.

3.2 Get an Access Token

Once the user has authorized your application, a request will be made to your application'sspecified redirect_uri which includes a code parameter that you must then use to get an Access Token.

POST /api/v1.1/o/token/

Submit your newly granted Authorization Code and your application's credentials to receive an Access Token and Refresh Token. The code is valid for 60 seconds and cannot be used more than once.

Request Headers:

 

-   **Authorization** – HTTP basic authentication using your
    application's `client_id` and
    `client_secret`

Form Parameters:

 

-   **grant_type** – MUST be set to `authorization_code`
-   **code** – The authorization code received from the user's
    redirect request.
-   **redirect_uri** – The same `redirect_uri`
    used in the authentication request.

**Example Request**

Using an authorization code to get an access token.

    POST /api/v1.1/o/token/ HTTP/1.1
    Host: www.docker.io
    Authorization: Basic VGVzdENsaWVudElEOlRlc3RDbGllbnRTZWNyZXQ=
    Accept: application/json
    Content-Type: application/json

    {
        "grant_type": "code",
        "code": "YXV0aG9yaXphdGlvbl9jb2Rl",
        "redirect_uri": "https://my.app/auth_complete/"
    }

**Example Response**

    HTTP/1.1 200 OK
    Content-Type: application/json;charset=UTF-8

    {
        "username": "janedoe",
        "user_id": 42,
        "access_token": "t6k2BqgRw59hphQBsbBoPPWLqu6FmS",
        "expires_in": 15552000,
        "token_type": "Bearer",
        "scope": "profile_read email_read",
        "refresh_token": "hJDhLH3cfsUrQlT4MxA6s8xAFEqdgc"
    }

In the case of an error, there will be a non-200 HTTP Status and and
data detailing the error.

3.3 Refresh a Token

Once the Access Token expires you can use your refresh_token to have docker.io issue your application a new Access Token, if the user has not revoked access from your application.
