api integration php curl

Question

I am trying to integrate an API, and in the API integration instructions it shows the following:

GET /offers.json or /offers.xml
Headers: API-KEY={your_key}, API-LOGIN={your_login}

CURL Example:

curl https://api.thewebsite.com/v1/offers.json -H 'API-KEY:
1a2b3c4d5e6f7g8h9i' -H 'API-LOGIN: 1a2b3c4d5e6f7g8h9i'

I've tried using the cURL code below without success. As for the GET method, I'm not sure how to pass the API KEY & API LOGIN as headers.

$header = array('Content-Type: application/xml', 'API-KEY=1a2b3c4d5e6f7g8h9i', 'API-LOGIN=1a2b3c4d5e6f7g8h9i');
$url = "https://api.thewebsite.com/v1/offers.xml";

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
$xml = curl_exec($curl);
curl_close($curl);

print $xml;

Solution

HTTP headers need to be specified using a colon as the separator between the key and the value, not an equal sign. Try this:

$header = array('Content-Type: application/xml', 'API-KEY: 1a2b3c4d5e6f7g8h9i', 'API-LOGIN: 1a2b3c4d5e6f7g8h9i');
