Questions and answers
What is the Yandex.Direct API and what can I use it for?
The API for the Yandex.Direct service provides programmatic access to data and allows you to create applications for managing advertising campaigns. External applications use the API to add and edit campaigns, ads and phrases, set bids, and get impression statistics.
The Direct API is intended primarily for advertising agencies and direct advertisers — commercial companies, businesses in the service sector, and others. Developing their own custom applications allows them to fully implement their own approaches to running advertising campaigns, get timely statistical reports, and more accurately forecast their budgets.
Is there a difference in managing an advertising campaign using the API and using the web interface?
The API has more features than the web interface. In particular, you can use the API to create and edit ad groups — multiple variations of an ad with the same set of keywords and other display settings.
All changes made via the API are reflected in your advertising campaigns.
Which technologies are supported in the API?
Requests to the Direct API are made over the HTTPS protocol using the POST method. Input and output data structures are passed in the body of the request and response.
Authentication uses the OAuth 2.0 protocol: requests must specify the access token.
How much does it cost to use the API?
Both connection to the Direct API and usage are free of charge.
How do I connect to the API?
The application developer must complete the application registration process.
An API request is made on behalf of a Direct user — an advertiser or advertising agency. The request must specify the access token, which is a special code allowing the application to perform operations with this user's data.
To get a token, the application must redirect the user to the access request page. The user authenticates in Yandex (using his username for Direct) and clicks the Confirm button. All other actions are performed automatically by the application and the Yandex server.
Who should register the application?
The application developer registers the application on the Yandex OAuth server and creates a request for access to the Direct API. This only needs to be done once, regardless of the number of copies of the application.
If you purchased or use a ready-made program, you do not need to register the application or submit the access request.
How do I get a token for a user?
To get a token, the app must redirect the user to the access request page, which is a special page on the Yandex OAuth server. The user authenticates on Yandex (using his login name in Direct) and grants the app access to personal data. The Yandex OAuth server generates a token and passes it to the app.
The procedure for getting a token is described in detail in the OAuth authentication guide.
Note. At the app development stage, you can get a debugging token in the name of a test user. See the section Debugging token in the OAuth authentication guide.
Why did the token become invalid?
A token might become invalid if, for example, the user's password changed on Yandex. For the full list of reasons, see the section Discontinuation of a token. In this case, a new token must be obtained.
If it is a problem for the app to get a new token (for example, the app updates bids automatically and does not interact with the user), we recommend registering a separate account in Direct as the representative of a client or agency. If this account will only be used in the app and not in the browser, there is minimal risk of it being compromised, and the password can be changed less often than normally.
What restrictions are there on API usage?
There are several types of restrictions in the API.
Direct API access is not available for users of the Light web interface. These users will need to switch to the Professional web interface.
Clients of advertising agencies can get API access:
An agency sets up access permissions for its clients using the UpdateClientInfo method, and also in the web interface (the edit campaign option on the page for editing client settings).
API access may be restricted by IP address, for increased information security. The list of allowed IP addresses can be specified on the Direct API access management page on the Settings tab.
Once per day, points are awarded to each API user. They do not accumulate, and are awarded starting from zero each day. Points are used as a method of paying for certain API operations (see below). If you do not have enough points, you cannot perform these operations. The GetClientsUnits method returns the number of points available to the user.
Points are used when calling the following methods:
The more efficiently you use Yandex.Direct, the more points you will be awarded. Inefficient use is generally associated with creating ads that are rejected during moderation or adding phrases that have a low CTR. These sorts of practices waste the resources of Yandex.Direct and are not encouraged.
Efficient use of Yandex.Direct is associated with searching for successful keywords and ad texts that raise the CTR. The number of points also depends on the campaign size and advertising expenditures. This means that more points are awarded to users who have a higher campaign balance and higher bids.
How can I increase the number of points available to me?
You can increase the number of available points by optimizing your advertising campaigns. You can do this by adding and refining keywords, improving the text of your ad to increase the CTR, and increasing your minimum bids. Points are recalculated and awarded every 24 hours.
Show me code examples for Yandex.Direct API clients
Application samples in various programming languages are provided in the documentation:
How do I download the report file?
How frequently can I call the GetReportList and GetForecastList methods?
Check report readiness in a single thread, no more than once every 10-30 seconds. We recommend increasing the interval before each consecutive check, for example: 10, 20, 40, ... seconds. For details, see the section Requirements for an app.
How frequently can I update bids?
Recommendations on the frequency of updating bids are provided in the section Requirements for an app.
How can I view the XML code of the request and the server response?
For detecting errors and debugging, sometimes you need to output the client's SOAP request and the server's SOAP response.
Where can I get help if I encounter problems using the API?
