Deals not ending up in right stage + pipeline

We have a fairly straightforward piece of code to add deals to Pipedrive. Deals are added, but for some reason they do not end up in the correct stage/pipeline.

$deal = array(
  'title' 		=> $firstName.' '.$lastName.' API import',
  'value' 		=> $value,
  'person_id' 	=> $personId,
  'status'		=> 'won',
  'pipeline_id'	=> 5, 
  'stage_id'	=> 30  
$url = 'https://' . $company_domain . '' . $api_token;
$dealCurl = curl_init();
curl_setopt($dealCurl, CURLOPT_URL, $url);
curl_setopt($dealCurl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($dealCurl, CURLOPT_POST, true);
curl_setopt($dealCurl, CURLOPT_POSTFIELDS, $deal);
$output = curl_exec($dealCurl);
$result = json_decode($output, true);

$dealId = $result['data']['id'];

I have no idea why this is going south.
