Hi there! Let me have a look at how this works

did you add the permissions in your app's manifest as outlined here? https://docs.stripe.com/stripe-apps/events

yup

 "permissions": [
    {
      "permission": "event_read",
      "purpose": "Read webhook event data"
    },
    {
      "permission": "customer_read",
      "purpose": "Read customer data to sync with Brevo"
    },
    {
      "permission": "customer_write",
      "purpose": "Update customer metadata for sync tracking"
    },
    {
      "permission": "product_read",
      "purpose": "Read product information for list mapping"
    },
    {
      "permission": "payment_intent_read",
      "purpose": "Track customer purchases to assign Brevo lists"

acct_1SCoMuAkuYgQhpSE is connected to the app owned by acct_1SIbGpAtgmAS7cnz, a sandbox of your main account, but no connect webhook endpoint is registerd on that account

left ridge acct_1SCoMuAkuYgQhpSE is connected to the app owned by acct_1SIbGpAtgmAS7cnz, a ...

ok this is weird now because when I visist https://dashboard.stripe.com/acct_1SIbGpAtgmAS7cnz/apps, there is nothing under "created apps"

#

buuut, the created app does show under https://dashboard.stripe.com/acct_1SHxH0AG2pP9ZMMq/apps

#

so when I upload a test version of the app, does it have its own sandbox as the owner and the UI just doesnt match?

🤔

#

Still looking but a colleague of mine that knows more about Stripe apps will be coming online in about 5 minutes, and I may need to hand you off to them

swift kindle Oct 15, 2025, 10:11 PM

#

all good, I added a webhook to the acct_1SIbGpAtgmAS7cnz account and I am now receiving events, but I still would want to clear up the confusion regarding the app owners

left ridge Oct 15, 2025, 10:13 PM

#

did you install the app on acct_1SCoMuAkuYgQhpSE in sandbox mode?

swift kindle Oct 15, 2025, 10:14 PM

#

yeah that was where I previously installed it to test

#

I just added a new customer after adding the new webhook endpoint and it sent succesfully

@little burrow 👋

#

Hi 👋

I'm stepping in as my colleague has to go soon. I looked up what I think is your app.

com.example.mailsync right?

swift kindle Oct 15, 2025, 10:31 PM

#

correct

little burrow Oct 15, 2025, 10:32 PM

#

Okay I can see that, internally, we have acct_1SHxH0AG2pP9ZMMq listed as the App Merchant account.

#

And I see Test installs for acct_1SCoMuAkuYgQhpSE, acct_1SHxHgAHRLKA1iaY, and acct_1SHxH0AG2pP9ZMMq

#

Does that line up with what you are seeing on your end?

swift kindle Oct 15, 2025, 10:33 PM

#

yes correct

little burrow Oct 15, 2025, 10:33 PM

#

Okay cool. So what is the state of receiving the webhook events?

swift kindle Oct 15, 2025, 10:33 PM

#

the webhooks are sent through a webhook endpoint defined on the account acct_1SIbGpAtgmAS7cnz which is what is confusing

little burrow Oct 15, 2025, 10:35 PM

#

Okay I can understand that. But both acct_1SCoMuAkuYgQhpSE and acct_1SHxHgAHRLKA1iaY are sandbox accounts so they would not send webhook events to non-sandbox accounts. However, the switch to sandboxes did create some rough edges with Stripe Apps. I can double check on whether or not this is expected behavior.

swift kindle Oct 15, 2025, 10:36 PM

#

ahh ok so if I install the app on a non-sandbox account the merchant account should have the events forwarded to it?

little burrow Oct 15, 2025, 10:39 PM

#

Yes. That is what I expect. I built a Stripe Apps extension before Sandboxes and even installing in Test mode still sent webhook events to the App developer account.

Personally I found it useful to create a second stand-alone Stripe account just for the purpose of performing an External Test.

swift kindle Oct 15, 2025, 10:40 PM

#

perfect I will try that out

little burrow Oct 15, 2025, 10:40 PM

#

I have both App Developer and App Installer accounts associated with my Stripe login 😅

swift kindle Oct 15, 2025, 10:40 PM

#

im gonna do that rn thats smart

little burrow Oct 15, 2025, 10:40 PM

#

It might seem like overkill but some of this stuff is hard to test otherwise

swift kindle Oct 15, 2025, 10:40 PM

#

yeah thats what Im learning haha

little burrow Oct 15, 2025, 10:41 PM

#

Best of luck!

And if you have any more issues, we'll be here
