AdGuard DNS provides a REST API you can use to integrate your apps with it.

Authentication

Generate Access token

Make a POST request for the following URL with the given params to generate the access_token:

https://api.adguard-dns.io/oapi/v1/oauth_token

Parameter	Description
username	Account email
password	Account password
mfa_token	Two-Factor authentication token (if enabled in account settings)

In the response, you will get both access_token and refresh_token.

• The access_token will expire after some specified seconds (represented by the expires_in param in the response). You can regenerate a new access_token using the refresh_token (Refer: Generate Access Token from Refresh Token).

• The refresh_token is permanent. To revoke a refresh_token, refer: Revoking a Refresh Token.

Example request

$ curl 'https://api.adguard-dns.io/oapi/v1/oauth_token' -i -X POST \
    -H 'Content-Type: application/x-www-form-urlencoded' \
    -d 'username=user%40adguard.com' \
    -d 'password=********' \
    -d 'mfa_token=727810'

Example response

{
  "access_token": "jTFho_aymtN20pZR5RRSQAzd81I",
  "token_type": "bearer",
  "refresh_token": "H3SW6YFJ-tOPe0FQCM1Jd6VnMiA",
  "expires_in": 2620978
}

Generate Access Token from Refresh Token

Access tokens have limited validity. Once it expires, your app will have to use the refresh token to request for a new access token.

Make the following POST request with the given params to get a new access token:

https://api.adguard-dns.io/oapi/v1/oauth_token

Parameter	Description
refresh_token	REFRESH TOKEN using which a new access token has to be generated.

Example request

$ curl 'https://api.adguard-dns.io/oapi/v1/oauth_token' -i -X POST \
    -H 'Content-Type: application/x-www-form-urlencoded' \
    -d 'refresh_token=H3SW6YFJ-tOPe0FQCM1Jd6VnMiA'

Example response

{
  "access_token": "xQnT7GYT6Ag--3oY_EcOOdXe-I0",
  "token_type": "bearer",
  "refresh_token": "H3SW6YFJ-tOPe0FQCM1Jd6VnMiA",
  "expires_in": 2627999
}

Revoking a Refresh Token

To revoke a refresh token, make the following POST request with the given params:

https://api.adguard-dns.io/oapi/v1/revoke_token

Request Example

$ curl 'https://api.adguard-dns.io/oapi/v1/revoke_token' -i -X POST \
    -d 'token=H3SW6YFJ-tOPe0FQCM1Jd6VnMiA'

Parameter	Description
refresh_token	REFRESH TOKEN which is to be revoked

Authorization endpoint

To access this endpoint, you need to contact us at devteam@adguard.com. Please describe the reason and use cases for this endpoint, as well as provide the redirect URI. Upon approval, you will receive a unique client identifier, which should be used for the client_id parameter.

The /oapi/v1/oauth_authorize endpoint is used to interact with the resource owner and get the authorization to access the protected resource.

The service redirects you to AdGuard to authenticate (if you are not already logged in) and then back to your application.

The request parameters of the /oapi/v1/oauth_authorize endpoint are:

Parameter	Description
response_type	Tells the authorization server which grant to execute
client_id	The ID of the OAuth client that asks for authorization
redirect_uri	Contains a URL. A successful response from this endpoint results in a redirect to this URL
state	An opaque value used for security purposes. If this request parameter is set in the request, it is returned to the application as part of the redirect_uri
aid	Affiliate identifier

For example:

https://api.adguard-dns.io/oapi/v1/oauth_authorize?response_type=token&client_id=CLIENT_ID&redirect_uri=REDIRECT_URI&state=1jbmuc0m9WTr1T6dOO82

To inform the authorization server which grant type to use, the response_type request parameter is used as follows:

• For the Implicit grant, use response_type=token to include an access token.

A successful response is 302 Found, which triggers a redirect to redirect_uri (which is a request parameter). The response parameters are embedded in the fragment component (the part after #) of the redirect_uri parameter in the Location header.

For example:

HTTP/1.1 302 Found
Location: REDIRECT_URI#access_token=...&token_type=Bearer&expires_in=3600&state=1jbmuc0m9WTr1T6dOO82

Accessing API

Once the access and the refresh tokens are generated, API calls can be made by passing the access token in the header.

• Header name should be Authorization
• Header value should be Bearer {access_token}
