Budget API

Introduction

The CityGrid Budget API allows publishers to discover the advertisers with budget available to them in the network and check the available remaining budget of a particular advertiser. Publishers who wish to check budgets must use this API so their quality score is unaffected by too many queries without subsequent clicks or user actions.

Discovering Opportunities

The budget API allows publishers to discover what advertisers have budget available at a particular moment in time by making accessible a report, generated on demand of the advertisers and budgets available.

HTTPS Endpoint

The following endpoint is used with HTTPS GET:

https://stream.api.citygridmedia.com/ads/budget/v2/discover

Request Parameter

The following query string parameters are used with the Budget API endpoint:

Parameter	Description	Required	Valid Values	Examples
publisher	The publisher code that identifies you. This parameter is required so that we can reflect the accurate budget.	Yes	Contact your account manager for your publisher code.	acme
format	The desired format for the result. Default is xml.	No	json, xml	xml
includeBudgetId	This parameter decides if a budget allocation Id would show in the result. Default is false.	No	true, false	true

Response

We use streaming instead of pagination for the response given that the result could be quite large. The response is a streaming-octet content type, which is a file with the result in XML or JSON based on the format specified in the request.

The table below describes the content of the response file. We also included an example of how to write a client to retrieve the response file using this method

Connecting to the streaming Discovery API

Accessing this API requires keeping a persistent HTTPS connection open. This involves thinking about your client application differently than if you are using a REST API. In other words, use this API as a separate process independent of user requests.

Connecting

To connect to the Discovery API, form an HTTPS request and download the response file. You must keep the connection open while you are downloading the file. This may be different for every language or framework.

We provide a simple client example to open a connection and download the response file

Client: (Using HttpClient, Framework independent)

String endpoint = " https://stream.api.citygridmedia.com/ads/budget/v2/discover?publisher=test&format=xml";
HttpGet httpGet = new HttpGet(endpoint);
HttpClient client = new DefaultHttpClient();
HttpContext context = new BasicHttpContext();
HttpResponse getResponse = client.execute(httpGet, context);
if (getResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
  int size = -1;
  OutputStream os = new FileOutputStream("result.xml");
  InputStream is = getResponse.getEntity().getContent();
  byte[] buffer = new byte[4096];
  while ((size = is.read(buffer)) != -1) {
    os.write(buffer, 0, size);
  }
  os.flush();
  os.close();
  client.getConnectionManager().shutdown();
}

Disconnecting

We will maintain the connection open until you close it but in some cases we may close your connection:

Too many connections are open for the same publisher code. There is no need to download the files multiple times in parallel since the result will be the same.
A client stops reading data suddenly. This probably means your connection got lost so we will close it for you
A server is restarted. This may happen in the case of a new release that needs system down time, but they are not frequent

Rate limits

We are not enforcing hard limits on this version of the API, but we ask that you don’t try to connect to this API over 5 times per day.

Checking Budget Available

The budget API also allows publishers to check what is the advertisers' budget available to them based on their traffic quality.
