Duplicate Emails with iDEAL…

Hi @ttoaster

Thanks for contacting us. The Stripe plugin does not control the order email logic, that is controlled by WooCommerce.

The order email logic is triggered anytime the order’s status is updated. When a payment is processed, the Stripe plugin calls the WC_Order::payment_complete method which is when WooCommerce takes over and does things like sending emails.

It sounds like you might have a plugin on your site that’s triggering the email notifications twice. Take a look at your order notes and see if the order’s status is transitioning from pending > completed or pending > processing just once or if it’s happening multiple times.

Kind Regards

Hi @ttoaster

Thanks for the order notes. I see that there are duplicate entries for the order status change and order charge success message. That would indicate you have 2 requests being received by your server at the same time.

Do you have a duplicate webhook setup? You can confirm this by going to stripe.com > developers >webhooks. If there are no duplicate webhooks, check your webserver configurations if you’re using NGINX as a proxy. Sometimes if NGINX is mis-configured it can send duplicate requests.

Something is causing 2 requests to come in at the same time. The requests are so close together that the order’s status is not being updated in the database before the next request gets processed. The emails are sent by WooCommerce when the order’s status transitions from pending to completed thus resulting in the duplicate emails.

This is not reproducible on our end and we don’t currently have any support tickets where a similar issue is described. The code for IDEAL is the same across most of the local payment methods in the plugin so if it were a plugin issue it would be happening for more than just IDEAL. Is IDEAL the only local payment method you offer on your site?

Kind Regards

Hi @ttoaster

This issue is not occurring with any of the others listed above, nor Credit Card, Apple Pay or Browser Payments.

Card payments, Apple Pay, and Browser Payments don’t rely on the webhooks so that’s not surprising. I would expect this to only affect local payment methods.

Does this happen to all iDEAL payments or just a certain percentage? It sounds like what could be happening is the plugin is processing the redirect from the iDEAL payment page back to your store correctly but at the same time the payment_intent.succeeded webhook is being received.

The plugin uses transients to place a lock on the order to prevent race conditions but it seems as if that’s behaving differently for you.

Can you locate the WooCommerce > Status > Logs wc-stripe log file with a timestamp that has one of these orders? I’d like to see what story the log file tells.

Kind Regards

Hi @ttoaster

I guess I’ll have to live with it then, and just field any questions from customers that may erroneously believe they have been charged twice for their order (or remove iDEAL as a payment option).

It would be my preference to help you get this issue solved if possible, it’s just hard without having all the information such as logging. But understand your point about privacy.

We’ll continue to try and re-create this on our end and let you know via this thread if we discover anything.

Kind Regards

@ttoaster do you have a staging site where more comprehensive testing using “test” mode can be performed and the duplicate email issue can be replicated?

If you do have a staging site and prefer to keep the url private, you can create a support ticket here.
