We had several successful subscription updates over the weekend, then one failed this morning.
The payments are also not showing upon the transaction page when this happens.

Hi Ron — thanks for the detailed info, that helps a lot.

You’re getting:

400 ERR
“Error: Invalid webhook data received.”
Event type: invoice.payment_succeeded
Debug log: can’t retrieve subscription cpt record!

This tells us two important things:

Stripe successfully processed payment

Your server rejected the webhook payload

Your code then failed to find the matching subscription CPT record

Since one subscription updated correctly today, this is very likely a data-matching issue, not a Stripe outage or global configuration problem.

What’s Actually Failing

Your system is receiving the event:

invoice.payment_succeeded

But when your webhook handler runs, it tries to:

Extract the subscription ID from the event

Find the corresponding subscription CPT (custom post type) record

Update it

And it fails here:
can’t retrieve subscription cpt record!

So the core issue is:

The Stripe subscription ID in the webhook does not match a subscription record in your database.

Why This Happens (Most Common Causes)
1️⃣ Subscription ID Not Stored Correctly

The Stripe subscription ID (e.g., sub_…) may:

Not be saved in post meta

Be saved under a different key

Be saved incorrectly

Have been deleted or overwritten

Two failing subscriptions suggests those specific records have bad/missing metadata.

2️⃣ Webhook Signature Validation Failing

Your message says:

“Invalid webhook data received.”

That error is commonly thrown when:

The webhook signature check fails

The raw body is modified before verification

The endpoint secret is wrong

The wrong mode (live vs test) is used

However…

Since one subscription worked today, your webhook secret is probably correct.

Thanks for the reply,

The most recent one that failed is a long time customer with over 30 successful subscription updates. Nothing has changed with this customer. Customer and subscription ID’s match.

I found a Stripe webhook IP address list and added it to the firewall allow list. Other than that I’m not sure what else I can do.

On the one that failed I see “Webhook type: customer.subscription.updated” and “Webhook type: invoice.paid” but no “Webhook type: invoice.payment_succeeded”
Also there is no payment record added to the transaction list.

Thanks
Ron

The invoice.payment_succeeded webhook is needed for sure. That’s the one our plugin uses. So if that hook is not getting triggered by Stripe, it needs an investigation.

Check the Developers → API versions section to see which version of the API is being used by your Stripe account.

Are you using the latest version of the Simple Membership plugin?
