unable to send out voice broadcast with callfire REST API

Question

I'm trying to send out an outbound call with the callfire REST API and am having some difficulty doing so. Here's my code (adapted from https://developers.callfire.com/docs.html#createVoiceBroadcast):

<?php
$username = '...';
$password = '...';

$data = array(
    'name' => 'Automation Test',
    'fromNumber' => '...',
    'recipients' => array(
        array('phoneNumber' => '...')
    ),
    'answeringMachineConfig' => 'AM_AND_ALIVE',
    'liveSoundText' => 'hello, world!',
    'machineSoundText' => 'hello, world!'
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'https://api.callfire.com/v2/campaigns/voice-broadcasts');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_USERPWD, $username . ':' . $password);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));

$result = json_decode(curl_exec($ch));

print_r($result);

The problem is in the response. It's as follows:

stdClass Object
(
    [httpStatusCode] => 415
    [internalCode] => 0
    [message] => Exception in API
)

The 415 status code is for "Unsupported Media Type" per https://en.wikipedia.org/wiki/List_of_HTTP_status_codes#4xx_Client_Error but since I'm not uploading any media that error doesn't really make a lot of sense.

Maybe my value for answeringMachineConfig is invalid. idk what AM_AND_LIVE is supposed to mean but it's in the example so I'm using it. If there's only a small number of possible values the documentation should say so..

Answer 1

You need to set content type to 'application/json'.

Answer 2

Old I know, but just ran across it. Perhaps:

'answeringMachineConfig' => 'AM_AND_ALIVE',

should be:

'answeringMachineConfig' => 'AM_AND_LIVE',

You wrote ALIVE instead of LIVE
