ViewsGTM - Do not fire an HTML tag if the customer refreshes the page
We have currently an order confirmation page on our website after the customer paid where information is sent to our analytics tools. If the customer refreshes the page, the information about his order is sent again to our analytics tool and then we get wrong/duplicate information in our orders statistics.
Is there an easy way to prevent this? The goal would be here to not trigger the custom html tag when the customer reloads the page. It should be only fired once.
Thanks!
Best, Victor

You can use PerformanceNavigation.type or PerformanceNavigationTiming.type respectively in a Javascript variable to find out if the page has been reloaded (the former is already marked as deprecated while the latter is still marked as experimental, so to be on the safe side you should probably check which one is supported by the browser and use that).
Then use the return value to detect reloads and block the tag depending on that.
An alternative would be to set a cookie or local storage entry with the transaction and block based on that.

We finally found another solution that seems to work: We used an additional trigger in GTM that prevent the info to be sent twice.
When calling the page for the first time, the condition is set to "false", and on each following request to that page it is set to "true".
We made some test orders and it seems to works correctly. Thanks!
