Klarna Pay Later option webhook is called twice

[patricksteenks]

Describe the bug We see that for Klarna Pay Later payments the webhook is called twice. I'm not sure way. This way we receive two requests for an order update in our shop, which processes the order two times. It seems like a bug in Mollie? The webhook should only be called once upon successfull payment.

Used versions

• Magento 2.4.5 Open Source
• Mollie 2.17.0

To Reproduce Steps to reproduce the behavior:

1. Order with payment option Klarna Pay Later
2. Authorize payment
3. In mollie.log you will see to calls to the webhook of payment succes. There is usually 1 minute between them.

Expected behavior I expect the webhook to be called only once when successfulll.

Actual behavior The webhook is called twice.

We are having the same issue since today. I'm afraid this is quite urgent since this is the case for all projects that offer "Klarna Pay Later" as payment method with the M2 mollie modules.

Hi @patricksteenks and @GioDeGruyter ,

We are collaborating with Mollie to investigate this matter and will keep you informed of our progress.

Same issue here. The two webhook calls are also visible in the Mollie backend in the order history.

Although it mixes up something in Magento (a second invoice with total of 0 is created and after shipping the order history entry states the captured amount is 0) within Mollie everything seems to work fine regarding the captured and settled amounts.

Same issue here. (second invoice with total of 0 for pay later orders)

[GioDeGruyter]

Some extra info: the second invoice contains the store credit used for an order. (If store credit has been used to pay for the order)

Same issue!

We also see multiple calls to webhooks with other payment methods. Do more people experience this?

[sfritzsche]

Yes. Found also multiple invoices for Klarna pay now.
