basically its expecting and cant find \Stripe\Webhook
the webhooks code i got from stripe calls that method and no one told me where to get it. I thought stripe would provide it
Im doing a local stripe cli thing and I trigger my webhook and it actually connects but does nothing , but as the log shows thats the why....
here is the webhook.php code and you can see line 24
<?php
// webhook.php
//
// Use this sample code to handle webhook events in your integration.
//
// 1) Paste this code into a new file (webhook.php)
//
// 2) Install dependencies
// composer require stripe/stripe-php
//
// 3) Run the server on http://localhost:4242
// php -S localhost:4242
require 'vendor/autoload.php';
// This is your Stripe CLI webhook secret for testing your endpoint locally.
$endpoint_secret = 'whsec_4t5bz2Fr85h6psqtB3HaTrhwIym5UnwH';
// $endpoint_secret = 'whsec_W2lAZaT9yumHS9dtaBjkKtUHmuYzCcmu';
$payload = @file_get_contents('php://input');
$sig_header = $_SERVER['HTTP_STRIPE_SIGNATURE'];
$event = null;
error_log(print_r('variable area accessed', TRUE));
try {
$event = \Stripe\Webhook::constructEvent(
$payload, $sig_header, $endpoint_secret
);
} catch(\UnexpectedValueException $e) {
// Invalid payload
http_response_code(400);
exit();
} catch(\Stripe\Exception\SignatureVerificationException $e) {
// Invalid signature
error_log(print_r('stripe exception area', TRUE));
http_response_code(400);
exit();
}
// Handle the event
switch ($event->type) {
case 'charge.failed':
$charge = $event->data->object;
error_log(print_r('charge failed', TRUE));
case 'charge.succeeded':
$charge = $event->data->object;
error_log(print_r('charge succeeded', TRUE));
case 'subscription_schedule.canceled':
$subscriptionSchedule = $event->data->object;
error_log(print_r('sub cancelled', TRUE));
case 'subscription_schedule.created':
$subscriptionSchedule = $event->data->object;
//do othere stuff
$myfile = fopen("test.txt", "w") or die("Unable to open file!");
$txt = "Subscription created\n";
fwrite($myfile, $txt);
$txt = "2nd line\n";
fwrite($myfile, $txt);
fclose($myfile);
error_log(print_r('sub created', TRUE));
// ... handle other event types
default:
echo 'Received unknown event type ' . $event->type;
}
http_response_code(200);
this is line 24 $event = \Stripe\Webhook::constructEvent(

Okay. I'm not super familiar with PHP but let me take a look
Are you including the stripe library?
Can you take a look here: https://github.com/stripe/stripe-php#composer
glass wedge
basically the webhook.php file contains the webhooks sample code from stripe docs. but the code seems to expect the stripe-php library, which I use to have a folder , or method called webhooks
I believe thats whats happening, but not sure, hence why im here 🙂
frosty warren
Yeah you cannot just copy/paste the sample code and expect it to work if you haven't included the stripe-php library
glass wedge
I actually did use composer to install that very same stripe library, so it should have all I need. and I have the autoload line in my code. so it should have everything and access to stripe library. I see the folder composer brought in also locally.
I have been using the stripe library so far and know it works, cause Im using it to send payments and that is working fine and already done coded. im just now working on the webhooks part and seeing this error with the code from stripe
frosty warren
That sounds like something is wrong in your project configuration such that the webhook code cannot find the stripe-php library
glass wedge
ok im trying some things. im adding code I have on payments page to this page to see if those includes work. on the payments page I have
require_once 'stripe-php/init.php';
glass wedge
ok it worked!
frosty warren
Hooray 🎉
glass wedge
seems like autoload dis not auto loading via composer like is expected, for some reason, BUT when I manually load the stripe library with // Include Stripe PHP library
require_once 'stripe-php/init.php'; the error goes away and the webhook did its job and my local code only runs for the trigger its looking for, so im a happy camper. Once again you guys and or gals have made my day thank you
frosty warren
Happy to help 👍
glass wedge
my only question is that on the dashboard, teh webhooks I setup is not reporting any being successful. says all failed. nothing under succeded. thinking If it connected and no errors, it should be a success. do I have to manually send a 200 response code for that to happen?
frosty warren
Yes you have to return a 200 response
frosty warren
The server that is reached by that URL is apparently not returning the correct response though.
glass wedge
the stripe docs is not clear, if it mentions it at all, that we have to do that
and how
I mean, if there is a charge my webhook would fire and I can get info and take action, so technically all is fine on my end, just wondering why dashboard is saying 45 failed webhooks and zero successfull, and all is working
here is my code that runs successfully and at the end is the 200 response code
$myfile = fopen("test.txt", "w") or die("Unable to open file!");
$txt = "Subscription created\n";
fwrite($myfile, $txt);
$txt = "2nd line\n";
fwrite($myfile, $txt);
fclose($myfile);
error_log(print_r('sub created', TRUE));
http_response_code(200);
frosty warren
But is that code reachable on the server?
Or is this working on your local machine?
glass wedge
good question. you thinking its just a side affect of me using the stripe cli to do local testing? If so I would expect the stripe cli page to mention that fact
frosty warren
It's not a side effect
It's that the events are sent to both webhooks
and the code to respond to it does not exist on the server so those webhook requests are failing
glass wedge
It's that the events are sent to both webhooks
not sure what you mean by BOTH, mine and which other one?
frosty warren
The local listener and the one that is reached at https://simpleincometracker.com
glass wedge
ok I get that, but isnt the whole idea behind me using stripe client that I get to test same as production, here on local machine?
if im sending triggers from local stripe cli, why is it expecting from my production server. I have the dashbord webhook set to localhost etc
frosty warren
Only if production is synced to your local machine
It doesn't matter where the events come from. If they are on your account, using your secret_key then those events get sent to any and all webhook endpoints listening to those event types
Every event you trigger from the CLI will hit the URL you specified
Unless that server is configured to respond, it will cause an error
glass wedge
so I was right, in a way then, a "side effect" of using stripe cli is that you can NOT see a successfull webhook trigger.
glass wedge
which server?
frosty warren
You would have no problems if your server at that URL did what your local machine is configured to do
glass wedge
what do you mean by That URL, localhost:80/income/webhook.php?
frosty warren
The one in the screen shot with all the errors
glass wedge
cause thats the webhook point I have set in dashboard, the only one
frosty warren
In the image you sent, the URL specified was simpleincomtracker.com
glass wedge
although you see simpleincometracker.com, there is no webhook set there , yet. Im testing and so my webhook is set to the localhost being triggered by stripe cli
frosty warren
That's the problem
Because you have that entry in the Stripe dashboard, it means POST request are being sent to that URL
end of story
You can disable that endpoint while you are testing to avoid the failed requests
glass wedge
ok so you are basically saying that the webhook would succeed on my production server and can never do so on local testing...right?
cause i can live with that
glass wedge
You can disable that endpoint while you are testing to avoid the failed requests
the only way I can test is to have that local webpoint 🙂
frosty warren
the only way I can test is to have that local webpoint 🙂
A hosted endpoint is different from a local listener
glass wedge
ok so you are basically saying that the webhook would succeed on my production server and can never do so on local testing...right?
cause i can live with that
frosty warren
No that is not what I am saying. Let me explain.
You can configure a local listener using the Stripe CLI and stripe listen
This is separate from the Hosted Endpoints you see on the Webhooks tab of the Developer page on the Stripe Dashboard
However, both endpoints will be sent webhook POST requests when you A) trigger events with the Stripe CLI or B) trigger them through actions like creating a paymentIntent.
From what you have said previously it seems that you do not have any function configured to respond on the server at simpleincometracker.com.
This is causing the errors.
I currently have a local listener running on my machine and I have a hosted endpoint, which is disabled. I can confirm that you can disable your hosted endpoint while still receiving events on your local listener.
does that make sense?
glass wedge
kinda, im almost there
frosty warren
Okay, great. Which part is unclear
glass wedge
I literally have NO end point on production, its all here locally
and the local endpoint IS responding 200 response code, why doesnt dashboard see and recognize this
how can we test locally if its relying on production input, THAT is what I cans understand
cant understand
frosty warren
What does the Webhooks tab look like on your Stripe dashboard
For reference, this is what mine currently looks like
Here I see 1 entry in Hosted Endpoints and 1 entry in Local Listeners
glass wedge
so I should remove the production one
frosty warren
You don't have to remove it. You can disable it so it doesn't receive the POST requests
That way you can just turn it back on when you're ready
glass wedge
ok this makes total sens now, just not immiedietely apparent to a novice.
I diabled it and running local trigger again, lets see what happens
frosty warren
Alright 👍
glass wedge
I forgot I had the production one there also. one moment while I trigger again
frosty warren
Okay, let me know how it goes
glass wedge
everything looks green on local end, but dashboard webhooks section still showing zero successful webhooks on graph
frosty warren
Yeah, local listener data doesn't show up in the dashboard
Those metrics are more for monitoring the health of your endpoint in production.
glass wedge
well thats good to know 🤣🤣
thats been my concern for the last 30 minutes of this conversation 🙂
frosty warren
Alright, well glad we got that sorted out.
glass wedge
this line here in webhooks code ...$subscriptionSchedule = $event->data->object;
Im assuming its the data response being sent by stripe to the enpoint right? so is$subscriptionSchedule an array? trying to figure how to access the info locally in my code
frosty warren
In that case I find it really useful to check out the Events tab on the screen you shared. You can select an individual event and see the event type as well as the data payload sent to your local machine.
glass wedge
ok cool. please take the rest of the day off. thank you very much, you are doing gods work. 🙏🙏
frosty warren
Will do! 🤣
glass wedge
just saw there is a microphone here, does this mean we could have talked with audio!!!
frosty warren
Nope, it's disabled because we are hopping between so many threads.
glass wedge
ok cool.
frosty warren
Also we like to maintain written records if we need to hand off to another Stripe employee
Helps use get better at our jobs
glass wedge
makes sense ciao!
