How to send array and object with curl - php

Question

I am a beginner with curl. I want to make a request where I post different data.
I have a code
$curl = curl_init();
$fields = (object) array(
'contactFilter' => (object) array(
'clicked_message.messageid' => '5',
'messages_sent.messageid' => '5'
),
'exportAttributes' => 'email',
);
$fields = json_encode($fields);
$fields_string = http_build_query($fields);
curl_setopt_array($curl, array(
CURLOPT_URL => "https://api.sendinblue.com/v3/contacts/export",
CURLOPT_HTTPHEADER => array(
'Accept: application/json',
'Content-Type: application/json',
'api-key: my-key-12345',
),
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => $fields_string
));
$response = curl_exec($curl);
Documentation says that I need;
contactFilter object (X= campaign id): {"clicked_message.messageid": X,"messages_sent.messageid": X}
and
exportAttributes` array of strings For example, `['fname', 'lname, 'email'].
how should my request should look like?

Answer 1

You need to use CURLOPT_POSTFIELDS to post the fields, for example
$fields = array(
'username' => "annonymous",
'api_key' => "1234"
);
$fields_string = http_build_query($fields);
Now use variable fields_string to send array data
curl_setopt($ch, CURLOPT_POSTFIELDS,$fields_string);
Your curl request will be look like
curl_setopt_array($curl,
array(
CURLOPT_URL => "https://api.sendinblue.com/v3/contacts/export",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => $fields_string
)
);
Updated Code-
$curl = curl_init();
$fields = (object) array(
'contactFilter' => (object) array(
'clicked_message.messageid' => '5',
'messages_sent.messageid' => '5'
),
'exportAttributes' => 'email',
);
$fields = json_encode($fields);
//$fields_string = http_build_query($fields);
curl_setopt_array($curl, array(
CURLOPT_URL => "https://api.sendinblue.com/v3/contacts/export",
CURLOPT_HTTPHEADER => array(
'Accept: application/json',
'Content-Type: application/json',
'api-key: my-key-12345',
),
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => $fields
));
$response = curl_exec($curl);
echo $response;
print_r($response);
