Authorization of third-party web-applications¶

Для того, чтобы авторизовать пользователя, необходимо перенаправить его браузер на URL https://www.admitad.com/api/authorize/, используя формат данных application/x-www-form-urlencoded и передав следующие параметры:

• * The app ID is available for the authorized publisher in their account (by clicking the “Show credentials” button).

Example of request:

https://www.admitad.com/api/authorize/?scope=advcampaigns banners websites&state=7c232ff20e64432fbe071228c0779f&redirect_uri=https://google.com/&response_type=code&client_id=cb281d918a37e346b45e9aea1c6eb7

If the user is not logged in, a dialogue box will be displayed offering to enter login and password.

After logging in, the user will be offered to authorize the application by providing access to required settings requested by means of parameter scope. A complete list of settings is available in the section of application access rights.

Upon successful app authorization the user’s browser will be redirected to redirect_uri, the URL specified when the authorization dialogue appears. The code to get an access token code will be transferred in GET-parameter to the specified address:

https://redirect_uri/?state=7c232ff20e64432fbe071228c0779f&code=c75ebf64ad48a352630b6d953ce365

In case of an error, the user’s browser will be redirected with the error code and description:

https://redirect_uri/?state=7c232ff20e64432fbe071228c0779f&error_description=client_id+cb281d918a37e346b45e9aea1c6eb7+doesn't+exist&error=invalid_client

To get access_token it is required to send POST request to URL https://api.admitad.com/token/ using data format application/x-www-form-urlencoded and transfer the following parameters:

Name	Required	Description
client_id	✔	ID of your application.*
client_secret	✔	Secret key of your application
code	✔	The code received at the previous stage of authorization (parameter redirect_uri).
grant_type	✔	Тип запроса authorization_code
redirect_uri	✔	Address, to which the user will be re-addressed after authentication (the domain of the indicated address must correspond to the main domain in the application settings).

The request should use HTTP Basic authentification with the use of client_id* and client_secret* as access settings. The header of authorization is a base64-encoded string that contains colon-concatenated client_id and client_secret.

• * The app ID (client_id) and secret key (client_secret) are available for the authorized publisher in the personal account (by clicking the “Show credentials” button).

Below is an example of forming a base64-encoded authorization header in Python 2.7 for client_id=’cb281d918a37e346b45e9aea1c6eb7’ and client_secret=’a0f8a8b24de8b8182a0ddd2e89f5b1’:

from base64 import b64encode
client_id='cb281d918a37e346b45e9aea1c6eb7'
client_secret='a0f8a8b24de8b8182a0ddd2e89f5b1'
data = client_id + ':' + client_secret
# data = 'cb281d918a37e346b45e9aea1c6eb7:a0f8a8b24de8b8182a0ddd2e89f5b1'
data_b64_encoded = b64encode(data)

Below is an example of a base64-encoded authorization header (the data_b64_encoded variable):

Below is an example of a request using a curl utility for client_id=cb281d918a37e346b45e9aea1c6eb7, where b64XXX is the base64-encoded authorization header:

curl -H 'Authorization: Basic b64XXX' -X POST https://api.admitad.com/token/ -d 'code=c75ebf64ad48a352630b6d953ce365&client_secret=a0f8a8b24de8b8182a0ddd2e89f5b1&grant_type=authorization_code&client_id=cb281d918a37e346b45e9aea1c6eb7&redirect_uri=https%3A%2F%2Fgoogle.com%2F'

Example of request:

POST /token/ HTTP/1.1
Host: api.admitad.com
Content-Type: application/x-www-form-urlencoded;charset=UTF-8

code=c75ebf64ad48a352630b6d953ce365&client_secret=a0f8a8b24de8b8182a0ddd2e89f5b1&grant_type=authorization_code&client_id=cb281d918a37e346b45e9aea1c6eb7&redirect_uri=https%3A%2F%2Fgoogle.com%2F

As a result of this request you will get a new access_token. The time to live of the token in seconds expires_in, refresh_token and additional information for users are returned as well:

{
    "username": "webmaster1",
    "first_name": "name",
    "last_name"': "surname",
    "language": "ru",
    "access_token": "4b8b33955a",
    "token_type": "bearer",
    "expires_in": 604800,
    "refresh_token": "ea957cce42",
    "scope": "advcampaigns banners websites",
    "group": "webmaster"
