I have never dealt with ionic ones, but according to the python example given in http://docs.ionic.io/v1.0/docs/push-sending-push , you should add an authorization header to the request.
private_key = YOUR_PRIVATE_API_KEY
b64 = base64.encodestring('%s:' % private_key).replace('\n', '')
req.add_header("Authorization", "Basic %s" % b64)
The PHP implementation of this python fragment will be like this:
<?php
$yourApiSecret = "YOUR API SECRET";
$androidAppId = "e2c77770";
$data = array(
"tokens" => "APA91bF2YePDKxE6K6vZYs2KQ27Z4mdehJg-EaZaPy10w-RHN5RUgC_P6Uie24Qu_M28j9bfZcbU6pu8Awofa8h2G5j9jABnebrVIUgKM5JcZPEJHYVW2NINirAm7VnSqGOrqm4YicAoI9Xiw5zkgTx4edqXIANLEhvqsqSCeq-_gAuzZB8wvrQ",
"notification" => "Hello World!"
);
$data_string = json_encode($data);
$ch = curl_init('https://push.ionic.io/api/v1/push');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'X-Ionic-Application-Id: '.$androidAppId,
'Content-Length: ' . strlen($data_string),
'Authorization: Basic '.base64_encode($yourApiSecret)
)
);
$result = curl_exec($ch);
var_dump($result);
push-, .
