Hi river, i'm not sure if you're here but im very desperate for a solution, since my application is not registering stripe webhooks. This is very strange.

#

thanks for replying btw!

#

Could you share the event type that you expected it to be sent and the object ID that could trigger the event?

turbid jay Apr 19, 2023, 3:36 AM

#

Well I was expecting the invoice.payment_succeeded event to be triggered after performing a test transaction but it did not work. Where can I find the object ID?

#

currently the test webhook is listening for all the events

spiral parrot Apr 19, 2023, 3:37 AM

#

Could you share the Invoice ID (in_xxx), so that I can check its event history?

turbid jay Apr 19, 2023, 3:37 AM

#

"id": "in_1MyRcCKlKqnPmqrpMOUdArt0" I believe its this one

spiral parrot Apr 19, 2023, 3:39 AM

#

invoice.payment_succeeded event for this invoice was sent, but your Webhook endpoint returned error 500: https://dashboard.stripe.com/test/events/evt_1MyRcFKlKqnPmqrppn6Y9sU2

#

this is wierd, im using ngrok.exe as a tunnel right now for testing, and I can run the application fine and send messages to it (it's a chatbot)

spiral parrot Apr 19, 2023, 3:40 AM

#

i'd recommend checking your ngrok settings. The error message from your server returned showed:

<!doctype html>
<html lang=en>
<title>500 Internal Server Error</title>
<h1>Internal Server Error</h1>
<p>The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.</p>

#

You may refer to this Dashboard page that Stripe tried to send the events to your Webhook endpoint: https://dashboard.stripe.com/test/webhooks/we_1MyRZmKlKqnPmqrpwWFChm9X

Okay now before you go, I also noticed another strange thing. Here is my stripe_webhook route:

@app.route('/stripe_webhook', methods=['POST'])
def stripe_webhook():
    event = None
    payload = request.data
    sig_header = request.headers['STRIPE_SIGNATURE']
     # Debug print statements
    print(f"Received STRIPE_SIGNATURE header: {sig_header}")
    print(f"Payload: {payload}")
    print(f"Endpoint secret: {endpoint_secret}")

    try:
        event = stripe.Webhook.construct_event(
            payload, sig_header, endpoint_secret
        )
    except ValueError as e:
        # Invalid payload
        raise e
    except stripe.error.SignatureVerificationError as e:
        # Invalid signature
        raise e

    if event['type'] == 'invoice.payment_succeeded':
        handle_successful_payment(event)
    elif event['type'] == 'invoice.payment_failed':
        handle_failed_payment(event)
    else:
      print('Unhandled event type {}'.format(event['type']))

as you can see I print my signature key from stripe, however when I sent any event I get this error:

Endpoint secret: whsec_IvvU34bfcXVEy3gPTMR7GBKrF5AO1yVH
ERROR:app:Exception on /stripe_webhook [POST]

However, that is NOT my endpoint secret key! Why is it not getting the endpoint secret key I set on my global variables? (whsec_TmwzP6NFrglFj245Ybgnea63iA4yXGZJ)

#

its not sending the correct secret key?

#

im just not getting it, my app works fine i can send and receive messages from my chatbot, and get 204 responses just fine.

spiral parrot Apr 19, 2023, 3:48 AM

#

I'm not too sure how you set your webhook secret in global variable since the code above only shows how endpoint_secret is used.

If you hard code the actual value of endpoint_secret in stripe.Webhook.construct_event, does it work?

turbid jay Apr 19, 2023, 3:50 AM

#

wait, I restarted my tunnel and now it seems to be working, but let me see if it will work in the deployed application one moment.

#

Ok im no longer getting the 500 error on my ngrok. Instead it is 200 now. However, in my webhook log, it does not show as succeeded?

Just to give a bit more info, this is a Flask application

#

Hi @turbid jay I'm taking over

turbid jay Apr 19, 2023, 3:57 AM

#

Hi jack, thanks river! have a good one

#

what time is stripe help available til?

stable light Apr 19, 2023, 4:02 AM

#

We are on discord Monday to Friday, and we have teams to cover various timezones.

#

It looks like your problem is resolved?

turbid jay Apr 19, 2023, 4:05 AM

#

Hmm not really, my live app on heroku is giving me this error:

WebhookSignature.verify_header(payload, sig_header, secret, tolerance)
2023-04-19T04:04:22.705819+00:00 app[web.2]: File "/app/.heroku/python/lib/python3.11/site-packages/stripe/webhook.py", line 74, in verify_header
2023-04-19T04:04:22.705820+00:00 app[web.2]: raise error.SignatureVerificationError(
2023-04-19T04:04:22.705820+00:00 app[web.2]: stripe.error.SignatureVerificationError: No signatures found matching the expected signature for payload

however I double and triple chekced my live keys in the env variables and they are correct.

#

I fixed the issue in my local development server by simply restarting ngrok but in heroku is another story.

#

So im not sure what to do

#

I restarted the dynos

#

but still

#

should I delete the webhook and create a new one?

stable light Apr 19, 2023, 4:11 AM

#

This error usually means the webhook secret is incorrect. Are you setting up endpoints for both live mode and test mode?

turbid jay Apr 19, 2023, 4:13 AM

#

yep, in test mode it works fine in my local development server. but it wont work in live. why?

stable light Apr 19, 2023, 4:17 AM

#

Are you using the same webhook secret in both test and live?

turbid jay Apr 19, 2023, 4:19 AM

#

Just created a new sk key, added it to my heroku config vars and also put the webhook signining secret key and im getting this error:

#

im so confused, restarted the dynos 3 times now

#

even made a NEW webhook

stable light Apr 19, 2023, 4:26 AM

#

Still waiting for your answer->Are you using the same webhook secret in both test and live?

turbid jay Apr 19, 2023, 4:27 AM

#

No they are different, however remember that heroku apps have their env vairables on the server and locally i have another set of env file.

#

I just confirmed my theory, locally it works fine, but in heroku it doens't it says signatureverificationerror, etc

#

this seems to be a problem from your side

stable light Apr 19, 2023, 4:32 AM

#

I'd suggest to put some logs in your application to verify if the correct secret is used in your endpoint.

turbid jay Apr 19, 2023, 4:33 AM

#

I will and I will show you that the error is being caused because it is being sent a diffrent endpoint from the one in stripe dashboard. Not even hardcoding it will fix it give me a moment.

#

Hmm i added the print statement and it is this:

#

#

they are the same, why is it giving me an error then?

stable light Apr 19, 2023, 4:42 AM

#

event ID?

turbid jay Apr 19, 2023, 4:43 AM

#

"id": "cus_NjwGxH3XULvaKo",

stable light Apr 19, 2023, 4:43 AM

#

An event ID starts with evt_

turbid jay Apr 19, 2023, 4:45 AM

#

oh yes my bad sorry "id": "evt_1MySO4KlKqnPmqrpP0QJZ8Qu",

stable light Apr 19, 2023, 4:48 AM

#

Your endpoint responds with

<p>The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.</p>

turbid jay Apr 19, 2023, 4:48 AM

#

yes but that cant be right because right now my application is receiving requests and giving responses just fine

#

In the sample code it's getting the signature from stripe-signature, but your code is getting it from STRIPE_SIGNATURE'

turbid jay Apr 19, 2023, 4:51 AM

#

Hmm, okay! let me see

#

damn no 😦 still getting the same error

stable light Apr 19, 2023, 4:57 AM

#

Put a log to print out he signature that you receive

turbid jay Apr 19, 2023, 4:57 AM

#

one moment

#

here is the header and secret endpoint:

2023-04-19T04:59:51.677309+00:00 app[web.1]: Endpoint secret: whsec_3QROalhNXD5xhpbOC14X2R6nNE3Wf34U```

#

hmm?

stable light Apr 19, 2023, 5:09 AM

#

Is the request.data a raw data or parsed json data ?

turbid jay Apr 19, 2023, 5:10 AM

#

here is a sample of the request.data:

Payload: b'{\n "id": "evt_1MyRfrKlKqnPmqrp1H1feTxc",\n "object": "event",\n "api_version": "2022-11-15",\n "created": 1681874834,\n "data": {\n "object": {\n "id": "in_1MyRfnKlKqnPmqrpnY30eK2h",\n "object": "invoice", Im not sure if its parsed or raw

#

What do you think?

#

Hey man I have to go now but could you please leave this open. This is an urgent issue and im simply lost on why its happening. I should be back in 6 hours

stable light Apr 19, 2023, 5:27 AM

#

A thread will be closed after some time, you can ask again in #dev-help when you are back

turbid jay Apr 19, 2023, 5:27 AM

#

Could you ask around why is this happening?
