Convert Terminal cURL Call to PHP cURL Request - php

Question

I am trying to send a cURL request from PHP to ExpressPigeon.com RESTFUL API.
The documentation says that this is how to create contact in a list using cURL command:
curl -X POST -H "X-auth-key: 00000000-0000-0000-0000-000000000000" \
-H "Content-type: application/json" \
-d '{"list_id": 11,
"contacts": [
{"email": "john#doe.net",
"first_name":"John",
"last_name": "Doe"
},
{"email": "jane#doe.net",
"first_name":"Jane",
"last_name": "Doe"
}] }' \
https://api.expresspigeon.com/contacts
Here's what I did:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://api.expresspigeon.com/contacts');
$fields = array(
'list_id' => $this->list_code,
'contacts' => array('email' => $param['email'], 'first_name' => $param['first_name'], 'last_name' => $param['last_name'])
);
$this->http_build_query_for_curl($fields); //This generates the $this->post_data
curl_setopt($ch,CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_POSTFIELDS, $this->post_data);
$headers = array(
'X-auth-key: '.$this->api_key,
'Content-type: application/json',
'Content-Length: '.strlen(serialize($post))
);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
$res = (array) json_decode(curl_exec($ch));
curl_close($ch);
print_r($res);
function http_build_query_for_curl( $arrays, $prefix = null )
{
if ( is_object( $arrays ) ) {
$arrays = get_object_vars( $arrays );
}
foreach ( $arrays AS $key => $value ) {
$k = isset( $prefix ) ? $prefix . '['.$key.']' : $key;
if ( is_array( $value ) OR is_object( $value ) ) {
$this->http_build_query_for_curl( $value, $k );
} else {
$this->post_data[$k] = $value;
}
}
}
I have this as a result though:
Array
(
[status] => error
[code] => 400
[message] => required Content-type: application/json
)

Answer 1

you need to add one more level of array nesting to achieve the desired JSON output so that contacts is an array instead of an object:
$fields = array(
'list_id' => $this->list_code,
'contacts' => array(array('email' => $param['email'], 'first_name' => $param['first_name'], 'last_name' => $param['last_name']))
);
and then use json_encode on that; you add debug printouts and compare against what you need

Support just replied and this is the working code. I've tried it and it works! The only thing I did not do is the the SSL parameters on cURL. Thanks to Hans Z for his revision on my contacts array.
$fields = array(
'list_id' => $this->list_code,
'contacts' => array(array('email' => $param['email'], 'first_name' => $param['first_name'], 'last_name' => $param['last_name']))
);
$requestBody = json_encode($fields);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://api.expresspigeon.com/contacts");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, true );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_POSTFIELDS, $requestBody);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json','X-auth-key:'.$this->api_key));
$result = curl_exec($ch);
curl_close($ch);
