Are they the same order though? My thought was, the order was finalized, but then Mollie notified you of the expired one and that has reset the paid one, but I could be reading your original post wrong.

Were the orders the same one?

The orders were from the same person with the same product at the same time.

The expired order in mollie is not visible in Vendr but we can find it in the database. The one that is approved in mollie is completely missing in Vendr, even in the database.

I don't know the exact timestamp since mollie doesn't register miliseconds AFAIK but it seems the completed one was the first to be handled by molly if I go by the sortorder:

The ordernumbers and payment Id's for both orders are generated by Vendr but the completed ordernumber and payment id are completely missing from the system.

I was thinking about a doubleclick on the checkout button but even then I should have 2 orders in Vendr right? Since the ordernumber is there?

verlopen == expired

Very weird,

Do you happen to have this Mollie provider hooked up to another environment by accident? Maybe this order was placed on a dev / test environment that was mistakenly configured with the live settings?

That's exactly the first thing I checked. It is hooked up to all environments but local and dev are in testmode.

The other thing that doesn't add up is that both orders in Mollie have exactly the same data, so the client name and everything is exactly the same.

Does that completed order id / number exist in any other environment? It would be very strange for it to be just entirely gone (unless the expired one overwrote it some how)

Hi Kevin,

You'd be better off raising this as a question of it's own. I'd aso do a search of the forum as there are a few posts of a similar situation.

Ultimately your issue is likely to boil down to your orders are some how being edited after the customer has been sent to the payment gateway, be that some code running in an event handler, or your customers navigating back to the site once the payment portal has been launched. Either way, changes to an order after you have gone to the payment gateway will result in the orders order number being reset and thus you'll see the issue you are seeing.

You'll need to review your site to see if you have any code modifying the order after this point, or figure out if your customers are doing something iregular and opening the order in multiple browser tabs etc and making changes after the orders has already been sent to Stripe.
