Orders duplicated issue

Hello,
Im having a issue in the case when user refresh multiple times the thankyou page, the orders is collected each time the page load and create a data accurary issue with our revenue report.

Here is an example

How to make possible that an order with same orderID is not count multiple times?

Thanks in advance

Hi @MMiraculeux, welcome to our community forum.

Is this a screenshot from today? We’ve introduced the Order ID deduplication mechanism with our latest release Version 16 - Piwik PRO.

Best,

@MMiraculeux No, everything should work fine now. Please check it on your end and confirm.

I recently uncovered this issue for a client of mine. I’m on the hosted core plan. I have looked at the data multiple times and there are definitely double-counts of a few orders, most likely due to customers refreshing the “thank you” page or leaving it in a browser tab, which they later return to.

Hi @David_Culbertson,

Would you be able to share some screenshots with examples or link to the website where I can check it via DM?

@Adam,

Here is the one example from the last seven days. Over the course of the month, there were roughly 10 duplicated orders that followed a similar pattern. Website sent to you via DM.

From the Ecommerce orders report:

From the Session Logs report:

Hi David,

As far as I can see this is not something that our deduplication mechanism can cover. It works within one session and if we discovered that there were two orders with the same order ID we can prevent from tracking it twice. However, your example is based on finished session and new session that started in the same place where previous was finished. I think this is something that can be fixed on your side, by redirecting users to a place where data in dataLayer is not available
