我们有一个案例，需要检查两个独立的Docusign帐户中的信封状态。如果我们在第一个中没有得到状态，我们想检查第二个。
我很难让API用我们第二个帐户的凭据重新初始化。我用新的变量调用这个片段：
require_once('docusign/SignatureApi.php');
$IntegratorsKey = "abcd";
$UserID = "dave@account.com";
$Password = "xxxxx";
$_apiEndpoint = $Endpoint;
$_apiWsdl = "docusign/api/APIService.wsdl";
$api_options = array('location'=>$_apiEndpoint,'trace'=>true,'features' => SOAP_SINGLE_ELEMENT_ARRAYS);
$api = new APIService($_apiWsdl, $api_options);
$api->setCredentials("[" . $IntegratorsKey . "]" . $UserID, $Password);
$res = RequestEnvelopStatuses($envelopes);
$envelopeStatuses = $res->RequestStatusesResult;
if(!count($envelopeStatuses->EnvelopeStatuses->EnvelopeStatus)){
// If we did not find envelopes, check other account
$IntegratorsKey = "wxyz";
$UserID = "fred@altaccount.com";
$Password = "xxxxx";
$api->setCredentials("[" . $IntegratorsKey . "]" . $UserID, $Password);
// retry request
$res = RequestEnvelopStatuses($envelopes);
$envelopeStatuses = $res->RequestStatusesResult;
}
它不会返回错误，但也不会返回信封状态。它似乎仍然使用第一个凭据（猜测）。无论第一次尝试做了什么，第二次尝试似乎总是会回来。
有更好/首选的方法吗？
这看起来不是获取信封状态的正确方法。也许这就是为什么你没有找到它们并试图再次寻找的原因？
// Create a filter using account ID and today as a start time
$envStatusFilter = new EnvelopeStatusFilter();
$envStatusFilter->AccountId = $AccountID;
$beginDateTime = new EnvelopeStatusFilterBeginDateTime();
$beginDateTime->_ = todayXsdDate(); // note that this helper function
// is in CodeSnippets/include/utils.php
// in the PHP SDK
$envStatusFilter->BeginDateTime = $beginDateTime;
// Send
$requestStatusesparams = new RequestStatuses();
$requestStatusesparams->EnvelopeStatusFilter = $envStatusFilter;
$response = $api->RequestStatuses($requestStatusesparams);
