Based on the Discourse API documentation, the Api_username and Api_key must be sent over HTTP request headers. Sending them as a GET params won’t work.

I tried and it failed. Therefore, I had wasn’t able to use IFTTT as it was instructed here…

However, I ended up writing a simple custom PHP script that acts as a relay hook that will allow data to be sent to discourse with the proper configuration.

Code
<?php
header('Content-Type: application/json');

//Make sure that it is a POST request.
if (strcasecmp($_SERVER['REQUEST_METHOD'], 'POST') != 0) {
    echo json_encode(array("error" => 'Request method must be POST!'));
}

//Make sure that the content type of the POST request has been set to application/json
$contentType = isset($_SERVER["CONTENT_TYPE"]) ? trim($_SERVER["CONTENT_TYPE"]) : '';
if (strcasecmp($contentType, 'application/json') != 0) {
    echo json_encode(array("error" => 'Content type must be: application/json'));
}

//Receive the RAW post data.
$content = trim(file_get_contents("php://input"));

//Attempt to decode the incoming RAW post data from JSON.
$payload = json_decode($content, true);

//If json_decode failed, the JSON is invalid.
if (!is_array($payload)) {
    echo json_encode(array("error" => 'Received content contained invalid JSON!'));
    die();
}

if (empty($payload['discourse_endpoint'])) {
    echo json_encode(array("error" => 'Discourse endpoint must be provided in the json body!'));
    die();
}

if (empty($payload['api_key'])) {
    echo json_encode(array("error" => 'Discourse API Key must be provided in the json body!'));
    die();
}

if (empty($payload['api_username'])) {
    echo json_encode(array("error" => 'Discourse API User must be provided in the json body!'));
    die();
}

$discourse_endpoint = $payload['discourse_endpoint'];
$api_key = $payload['api_key'];
$api_user = $payload['api_username'];

unset($payload['discourse_endpoint']);
unset($payload['api_key']);
unset($payload['api_username']);

$data_string = json_encode($payload);

$ch = curl_init($discourse_endpoint);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    "Api-key: $api_key",
    "Api-username: $api_user",
    'Content-Length: ' . strlen($data_string)
));
$result = curl_exec($ch);

echo $result;

?>
