Posting JSON data to API using CURL

Question

When I\'m posting json data to API using curl - I\'m not getting any output. I would like to send email invitation to recipient.

$         


        

Answer 1

You don't need to add headers as you already do json_encode. just print_r (curl_getinfo($ch)); and see the content type info in it.

Answer 2

Try adding curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
And changing http_build_query($post) to $post

The implementation:

<?php

$data = array(
  "authorizedKey" => "abbad35c5c01-xxxx-xxx",
  "senderEmail" => "myemail@yahoo.com",
  "recipientEmail" => "jaketalledo86@yahoo.com",
  "comment" => "Invitation",
  "forceDebitCard" => "false"
);

$url_send ="http://api.payquicker.com/api/SendInvitation?authorizedKey=xxxxx";
$str_data = json_encode($data);

function sendPostData($url, $post){
  $ch = curl_init($url);
  curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");  
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_POSTFIELDS,$post);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
  $result = curl_exec($ch);
  curl_close($ch);  // Seems like good practice
  return $result;
}

echo " " . sendPostData($url_send, $str_data);

?>

The response I get is:

{"success":false,"errorMessage":"Object reference not set to an instance of an object.","status":"N/A"}

But maybe it will work with valid data....

Edit: For posting xml, it's the same as on their site, except in a string:

$xml = '
<SendInvitationRequest xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/PQApi.Models">
  <authorizedKey>80c587b9-caa9-4e56-8750-a34b17dba0a2</authorizedKey>
  <comment>sample string 4</comment>
  <forceDebitCard>true</forceDebitCard>
  <recipientEmail>sample string 3</recipientEmail>
  <senderEmail>sample string 2</senderEmail>
</SendInvitationRequest>';

Then:

sendPostData($url_send, $xml)

Answer 3

You have to add header:

$headers= array('Accept: application/json','Content-Type: application/json'); 

And:

curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

Otherwise ...

HTTP Status 415 - Unsupported Media Type

... may happen.
