Get Started With the Bing Ads API

  • Artikel

Any Microsoft Advertising user with a developer token can begin using the Bing Ads API. For advertisers placing a large number of ads or developers building advertising tools, the Bing Ads API provides a programmatic interface to Microsoft Advertising.

You can develop your Bing Ads API application in any language that supports web services. To get started with a specific SDK, see Get Started in C# | Java | PHP | Python.

Get a user access token

Consider the user that you want to sign in e.g., example@contoso.com. The Bing Ads API will not accept that email address and password. Instead you need to set the AuthenticationToken header element that contains a user access token. You can think of an access token as representing a user name and password.

How can you get an access token for a user? As an application developer you'll use a Microsoft authorization URL to prompt the Microsoft Advertising user for consent. Once a user provides consent, you can get an access token and act on behalf of the user. The access token represents the user credentials who has access to one or more Microsoft Advertising accounts.

  1. Register an application

  2. Request user consent for your application to manage their Microsoft Advertising accounts

  3. Get access and refresh tokens

  4. Make your first API call

Tip

For details about how to get access and refresh tokens using the Bing Ads SDKs, see Authentication With the SDKs.

Get a Developer Token

To use Bing Ads APIs, you must have a developer token and valid user credentials. If you do not yet have a Microsoft Advertising account, you can sign up via the Microsoft Advertising web application.

Note

The sandbox and production environments use separate credentials. You can sign up for a Sandbox account here. Everyone can use the universal sandbox developer token i.e., BBD37VB98.

You can follow these steps to get a developer token for production.

  1. Sign in with Super Admin credentials at the Microsoft Advertising Developer Portal account tab.
  2. Choose the user that you want associated with the developer token. Typically an application only needs one universal token regardless how many users will be supported.
  3. Click on the Request Token button.

The universal developer token can be used to authenticate with any Microsoft Advertising user credentials. You can use the same universal developer token whether your application will be used by one or multiple Microsoft Advertising users. As of July 2019, this is the default token type.

The single-user developer token can only be used to authenticate one user for access to one customer. This token type has been deprecated in favor of the universal token. If you still see that a single user token is assigned to one of your users, you can select "Upgrade to Universal".

A developer token enables programmatic access to the accounts permitted for a user. Obtaining a developer token for API access does not grant additional permissions to any Microsoft Advertising accounts. Each Microsoft Advertising user is assigned a role e.g., Super Admin or Advertiser Campaign Manager for every customer they can access. With a developer token the same accounts available in the Microsoft Advertising web application are available to the user programmatically through the API.

Where to Use the API Credentials

When you call a service operation such as GetCampaignsByAccountId, you must specify request header elements such as DeveloperToken, CustomerId, and CustomerAccountId.

<s:Envelope xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header xmlns="https://bingads.microsoft.com/CampaignManagement/v13">
    <Action mustUnderstand="1">GetCampaignsByAccountId</Action>
    <ApplicationToken i:nil="false">ValueHere</ApplicationToken>
    <AuthenticationToken i:nil="false">ValueHere</AuthenticationToken>
    <CustomerAccountId i:nil="false">ValueHere</CustomerAccountId>
    <CustomerId i:nil="false">ValueHere</CustomerId>
    <DeveloperToken i:nil="false">ValueHere</DeveloperToken>
  </s:Header>
  <s:Body>
    <GetCampaignsByAccountIdRequest xmlns="https://bingads.microsoft.com/CampaignManagement/v13">
      <AccountId>ValueHere</AccountId>
      <CampaignType>ValueHere</CampaignType>
    </GetCampaignsByAccountIdRequest>
  </s:Body>
</s:Envelope>

If you are using one of the Microsoft Advertising SDKs, the request header elements are set using AuthorizationData. For more details about the SDK authentication library see Authentication With the SDKs.

var authorizationData = new AuthorizationData
{
    Authentication = <AuthenticationGoesHere>, 
    CustomerId = <CustomerIdGoesHere>,
    AccountId = <AccountIdGoesHere>,
    DeveloperToken = "<DeveloperTokenGoesHere>"
};

static AuthorizationData authorizationData = new AuthorizationData();
authorizationData.setAuthentication(<AuthenticationGoesHere>);
authorizationData.setCustomerId("<CustomerIdGoesHere>");
authorizationData.setAccountId("<AccountIdGoesHere>");
authorizationData.setDeveloperToken("<DeveloperTokenGoesHere>");

$authorizationData = (new AuthorizationData())
    ->withAuthentication($AuthenticationGoesHere)
    ->withCustomerId($CustomerIdGoesHere)
    ->withAccountId($AccountIdGoesHere)
    ->withDeveloperToken($DeveloperTokenGoesHere);

authorization_data = AuthorizationData(
    authentication = <AuthenticationGoesHere>,
    customer_id = <CustomerIdGoesHere>,
    account_id = <AccountIdGoesHere>,
    developer_token = '<DeveloperTokenGoesHere>'
)

Get Your Account and Customer IDs

To get a user's customer ID and account ID, you can sign in to the Microsoft Advertising web application and click on the Campaigns tab. The URL will contain a cid key/value pair in the query string that identifies your customer ID, and an aid key/value pair that identifies your account ID. For example, https://ui.ads.microsoft.com/campaign/Campaigns.m?cid=FindCustomerIdHere&aid=FindAccountIdHere#/customer/FindCustomerIdHere/account/FindAccountIdHere/campaign.

Tip

Do not mistake the account number for the account identifier. The account number is the system-generated account number that is used to identify the account in the Microsoft Advertising web application. The account number has the form xxxxxxxx, where xxxxxxxx is a series of any eight alphanumeric characters. The API service requests only use the account identifier, and never use the account number.

With the Customer Management API you can get the customer and account identifiers for each authenticated user.

Call GetUser with your Microsoft Advertising credentials and DeveloperToken. Within the Body set the UserId nil. The response will include a User object that contains the UserId.

<?xml version="1.0" encoding="utf-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header>
    <h:ApplicationToken i:nil="true" xmlns:h="https://bingads.microsoft.com/Customer/v13" xmlns:i="http://www.w3.org/2001/XMLSchema-instance" />
    <h:AuthenticationToken xmlns:h="https://bingads.microsoft.com/Customer/v13">OAuthAccessTokenGoesHere</h:AuthenticationToken>
    <h:DeveloperToken xmlns:h="https://bingads.microsoft.com/Customer/v13">DeveloperTokenGoesHere</h:DeveloperToken>
  </s:Header>
  <s:Body>
    <GetUserRequest xmlns="https://bingads.microsoft.com/Customer/v13">
      <UserId i:nil="true" xmlns:i="http://www.w3.org/2001/XMLSchema-instance" />
    </GetUserRequest>
  </s:Body>
</s:Envelope>

Then call SearchAccounts with the UserId returned via the previous step. The returned advertiser account (or accounts) will include account and customer identifiers.

<?xml version="1.0" encoding="utf-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header>
    <h:ApplicationToken i:nil="true" xmlns:h="https://bingads.microsoft.com/Customer/v13" xmlns:i="http://www.w3.org/2001/XMLSchema-instance" />
    <h:AuthenticationToken xmlns:h="https://bingads.microsoft.com/Customer/v13">OAuthAccessTokenGoesHere</h:AuthenticationToken>
    <h:DeveloperToken xmlns:h="https://bingads.microsoft.com/Customer/v13">DeveloperTokenGoesHere</h:DeveloperToken>
  </s:Header>
  <s:Body>
    <SearchAccountsRequest xmlns="https://bingads.microsoft.com/Customer/v13">
      <Predicates xmlns:a="https://bingads.microsoft.com/Customer/v13/Entities" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
        <a:Predicate>
          <a:Field>UserId</a:Field>
          <a:Operator>Equals</a:Operator>
          <a:Value>UserIdGoesHere</a:Value>
        </a:Predicate>
      </Predicates>
      <Ordering i:nil="true" xmlns:a="https://bingads.microsoft.com/Customer/v13/Entities" xmlns:i="http://www.w3.org/2001/XMLSchema-instance" />
      <PageInfo xmlns:a="https://bingads.microsoft.com/Customer/v13/Entities" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
        <a:Index>0</a:Index>
        <a:Size>10</a:Size>
      </PageInfo>
    </SearchAccountsRequest>
  </s:Body>
</s:Envelope>

Tip

See Search User Accounts Code Example for a code example that returns accounts for the current authenticated user.

Header elements reference

Bing Ads API service operations use Simple Object Access Protocol (SOAP) to exchange the request and response messages with the service operation. For more information, see Bing Ads API Services Protocol.

Each SOAP request must include the following SOAP headers, which contain the user's credentials.

Note

The CustomerAccountId and CustomerId elements are not applicable for the Customer Billing and Customer Management services.

Element Description Data Type
ApplicationToken This header element is not used and should be ignored. string
AuthenticationToken The OAuth access token that represents a Microsoft Account user who has permissions to Microsoft Advertising accounts. For more information, see Authentication with OAuth. string
CustomerAccountId The identifier of the account that owns the entities in the request. This header element must have the same value as the AccountId body element when both are required. This element is required for most service operations, and as a best practice you should always set it. string
CustomerId The identifier of the customer that contains and owns the account. If you manage an account of another customer, you should use that customer ID instead of your own customer ID. This element is required for most service operations, and as a best practice you should always set it. string
DeveloperToken The developer token used to access the Bing Ads API. string
Password This element is reserved for internal use and will be removed from a future version of the API. You must use the AuthenticationToken element to set user credentials. string
UserName This element is reserved for internal use and will be removed from a future version of the API. You must use the AuthenticationToken element to set user credentials. string
