I am trying to handle Mandrill's webhook data when I get a bounce I want Mandrill to tell my app which email it was and save various data in a MySql Database.
I am working with PHP here, according to Mandrill they send a URL I give them a $_POST request with JSON data.
Normally I would json_decode() this request, but when I do so, it appears to be blank. To me the JSON looks malformed, but perhaps I need to do something else with it first?
This is what I receive in my script:
[mandrill_events] =>
[{\"event\":\"hard_bounce\",\"msg\":{\"ts\":1365109999,\"subject\":\"This an example webhook message\",\"email\":\"example.webhook#mandrillapp.com\",\"sender\":\"example.sender#mandrillapp.com\",\"tags\":[\"webhook-example\"],\"state\":\"bounced\",\"metadata\":{\"user_id\":111},\"_id\":\"exampleaaaaaaaaaaaaaaaaaaaaaaaaa\",\"_version\":\"exampleaaaaaaaaaaaaaaa\",\"bounce_description\":\"bad_mailbox\",\"bgtools_code\":10,\"diag\":\"smtp;550 5.1.1 The email account that you tried to reach does not exist. Please try double-checking the recipient\'s email address for typos or unnecessary spaces.\"},\"_id\":\"exampleaaaaaaaaaaaaaaaaaaaaaaaaa\",\"ts\":1390483382},{\"event\":\"soft_bounce\",\"msg\":{\"ts\":1365109999,\"subject\":\"This an example webhook message\",\"email\":\"example.webhook#mandrillapp.com\",\"sender\":\"example.sender#mandrillapp.com\",\"tags\":[\"webhook-example\"],\"state\":\"soft-bounced\",\"metadata\":{\"user_id\":111},\"_id\":\"exampleaaaaaaaaaaaaaaaaaaaaaaaaa1\",\"_version\":\"exampleaaaaaaaaaaaaaaa\",\"bounce_description\":\"mailbox_full\",\"bgtools_code\":22,\"diag\":\"smtp;552 5.2.2 Over Quota\"},\"_id\":\"exampleaaaaaaaaaaaaaaaaaaaaaaaaa1\",\"ts\":1390483382}]
You have the magic_quotes option set in your server.
You can disable it, or simply remove the trailing slashes from the response and then do the json_decode:
$response = json_decode(stripslashes($_RESPONSE['mandrill_events']), true);

let url = Bundle.main.appStoreReceiptURL!
let receipt = NSData(contentsOf: url)?.base64EncodedString(options: [])
The receipt string works well when I send it to Apple servers, but when my server sends it i get this error:
"status":21002, "exception":"com.apple.its.drm.InvalidDrmArgumentException"
I have no clue why, especially since it was working yesterday.
Turns out the HTTP POST function variables were all being sent to APPLE.
I had thought the receipt=XXX&key=1234 were separated in the PHP Server side code.
But the '&' wasn't there so the receipt sent to Apple was XXXkey=1234
so com.apple.its.drm.InvalidDrmArgumentException means that the receipt data has an error/ extra data.
I've setup a basic webhook php page as modeled on the stripe documentation and listed below. When I send a test event from the Stripe webhooks dashboard, stripe responds "Test webhook sent successfully" with a blankk reponse. However, the output log file is not written to, no email is sent and there is nothing logged to the http server error log or the php error log. My php version is 5.3.3. What am I doing wrong?
<?php
error_reporting(15);
// Set your secret key: remember to change this to your live secret key in production
// See your keys here: https://dashboard.stripe.com/account/apikeys
require_once('vendor/autoload.php');
\Stripe\Stripe::setApiKey("secret_test_key");
$handle = fopen("webhook.log","a");
// Retrieve the request's body and parse it as JSON
$input = file_get_contents("php://input");
$event_json = json_decode($input);
// Do something with $event_json
if (fwrite($handle, $event_json) === FALSE) {
mail("mike#example.com","Cannot write to webhook.log","");
echo "Cannot write to webhook.log";
exit;
}
mail('mike#example.com','Webhook Event',$event_json);
header(':', true, 200);
//http_response_code(200); // PHP 5.4 or greater
?>
You have a few potential problems. As a quick rule of thumb, the best way to debug this is to start by triggering the event yourself, which you can do simply by loading up your webhook url in a browser yourself. Then you can test it directly and make sure it is doing what you expect it to be doing. There are obviously two possibilities:
Stripe is not triggering your webhook handler for some reason
Your handler is not properly logging itself
The latter first: it could be that Stripe is triggering your handler but it isn't logging that fact successfully. This would mean that both your email logging and file logging are failing. That is actually quite possible. Email logging with the mail function is actually very unreliable, unless you know for a fact that it works. Mail sent with the mail function is dropped silently by most modern email systems (gmail, etc) unless you have your DNS records properly configured, which most people don't. So unless you know for sure that your mail attempt is working properly, it probably isn't. If you also happen to have a permission issue in your attempt to write to a log file (which is not uncommon for a newly setup server), your logs could simply be failing. The easiest way to check that is to load up the webhook URL in a browser yourself. That way you know it is being triggered, and can know for sure if the issue is improper logging or Stripe not calling your webhook.
If you determine for sure that stripe isn't calling your webhook, the most likely culprit would be an invalid HTTPS certificate. Is your webhook connected via HTTPS (it should be)? If so, is it a valid certificate? You can tell your browser to ignore an invalid certificate when you browse your own site, but stripe will simply refuse to send the request if it encounters an invalid certificate.
If none of the above fixes it then it will be time for more digging, but I would start with those: they are probably the most likely problems.
The solution is that $event_json is an object and the fwrite failed because it expects a string not an object. By converting to an array and then serializing I was able to both write to the log and send the email.
$event_json = (array)json_decode($input);
$event = serialize($event_json);
I'm trying to create a web hook notification. The documentation of the service i want to use requires that i specify a URL where POST requests can be performed. This URL will receive the following object, in json format, and must respond with a Status Code between 200-299.
{
"type": "ping"
}
I don't know how to proceed making my server on localhost respond with a 200 status code. http_response_code(200) works well on live server but nothing seem to be happening on localhost.
Is there any way i can make it work with localhost?
I've included the link to the documentation here (i hope it's not against the rule).
I am thinking that you wouldn't have to send them the response. The webhook would know about the response. If it reached your URL successfully, it would be a 200 OK right off the bat. If the API is requesting a response back then I imagine that you would have to call it back somehow. Is this a well-known API? Any documentation?
The response code is in the response header, not in the content.
PHP defaults to a response code of 200, so if you don't mess with it at all, you should be good.
If you want to set a different response code (202 for example), just call:
http_response_code(202);
Or set the full header yourself:
header('HTTP/1.1 202 Accepted');
Proper way to explicitly set 200 (or any other) status code with http_response_code function is just as following (don't echo or json_encode it):
http_response_code(200);
It should force webserver to use 200 status code in it's response. However, webserver could possibly ignore it. To check what response code your webserver sends, use telnet or any REST tool like Postman
I have an application that allows me to send as sms in a url using my android phone as follows:
http://196.96.53.25/sendsms? phone=0724206400&text=Yusuf_kiprop
however, when I remove the underscore from the text as follows:
http://196.96.53.25/sendsms?phone=0724206400&text=Yusuf kiprop
I get an error that webpage is unavailable. What could be the issue?
If you are sending from php then encode the message like
$message=urlencode('Yusuf kiprop');
http://196.96.53.25/sendsms?phone=0724206400&text=$message
If you are checking it in the browser directly its not being url encoded thats why.
Try this insted-:
http://196.96.53.25/sendsms?phone=0724206400&text=Yusuf%20kiprop
I have this code:
$url="https://graph.facebook.com/me/friends?access_token=".$access_token."&fields=id,first_name,last_name&limit=10";
$content=file_get_contents($url);
Whenever I use this on a non authenticated user I should get feedback of OAuthException, which doesn't show up in the PHP the $content is empty. While if I copy the URL to the browser I get the result and I see the exception.
I want to detect if the user is logged in and the session data is valid.
What might be wrong?
Maybe Facebook decides whether to respond with exception feedback or with just no response depending on the contents of Accept HTTP header(s) you are sending (file_get_contents sends different HTTP headers than your browser).
