Get campaigns
PHP 5 using JSON with the file_get_contents function
This example shows a request using the Campaigns.get method, along with the result processing and output. To use the example, specify the OAuth access token in the input data. For a request on behalf of an agency, also specify the client login.
<?php
//--- Input data -------------------------------------------------------------------------//
// Address of the Campaigns service for sending JSON requests (case-sensitive)
$url = 'https://api.direct.yandex.com/json/v5/campaigns';
// OAuth token of the user to execute requests on behalf of
$token = 'TOKEN';
// Login of the advertising agency client
// Required parameter if requests are made on behalf of an advertising agency
$clientLogin = 'CLIENT_LOGIN';
//--- Preparing and executing the request -----------------------------------//
// Setting the request HTTP headers
$headers = array(
"Authorization: Bearer $token", // OAuth token. The word Bearer must be used
"Client-Login: $clientLogin", // Login of the advertising agency client

'SelectionCriteria' => (object) array(), // Criteria for filtering campaigns. To get all campaigns, leave it empty
'FieldNames' => array('Id', 'Name') // Names of parameters to get
)
);
// Transforming input parameters to JSON
$body = json_encode($params, JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES);
// Creating the stream context: setting HTTP headers and the request body
$streamOptions = stream_context_create(array(
'http' => array(

));
// Executing the request and getting the result.

//--- Processing request results ---------------------------//
