change.org登錄API調用

Question

我已經對change.org API進行了幾次API調用，並獲得了用戶配置文件詳細信息和用戶創建的請願單，現在我需要找到使用API​​登錄的方法。但我無法確定它爲什麼不工作。

這是代碼即可獲得申請

<?php 
$API_KEY = '32cf9810f982f95613cec5cce3154dc83966f2a89111661e6355938ad70b20f6'; 
$REQUEST_URL = 'https://api.change.org/v1/users/325635554/petitions'; 
//$PETITION_URL = 'https://www.change.org/p/kasun-pay-your-workers-overtime'; 
$parameters = array(
    'api_key' => $API_KEY, 
    //'petition_url' => $PETITION_URL 
); 
$query_string = http_build_query($parameters); 
$final_request_url = "$REQUEST_URL?$query_string"; 
$response = file_get_contents($final_request_url); 
$json_response = json_decode($response, true); 

echo $response; exit; 
?> 

響應

    ] 
} 

現在的名單登錄他們給這個API文檔。 https://github.com/change/api_docs/blob/master/v1/documentation/resources/petitions/signatures.md#post-signatures

auth_key string The petition authorization key. 

所以當我提出請求到此URL

https://api.change.org/v1/petitions/3623702/signatures

與post數據

api_key=32cf9810f982f95613cec5cce3154dc83966f2a89111661e6355938ad70b20f6&lastName=Hello&email=hello123%40gmail.com&firstName=World&city=Chennai&postal_code=00200&country_code=IN 

我得到這個錯誤。

{"result":"failure","messages":["authorization key cannot be found or is not granted"]} 

API密鑰 32cf9810f982f95613cec5cce3154dc83966f2a89111661e6355938ad70b20f6

祕密 6acc5384782f8449e2775c3abf7688ec89cfa1ac76c710f2a745ad5c323e5bc9

你需要發送一個RSIG變量

$parameters['rsig'] = hash('sha256', $query_string_with_secret_and_auth_key);
