Facebook Pixel Purchase event missing deduplication parameters

I have integrated my Facebook pixel SOLELY through the Facebook App channel with and tested data sharing set at both 'ENHANCED' and 'MAXIMUM'

I am receiving the following error which is resulting in my pixel tracking many more purchases than I am actually receiving:

You're sending Purchase events through both your pixel and the Conversions API, but they're not being deduplicated properly because not enough of these events are receiving an event_id parameter. Event instances sent without an event_id parameter cannot be deduplicated.
 
Any ideas about how I could go about fixing this?

 Hi @darkelia19 ,

 

Have you checked your events on the checkout page using Facebook Pixel Helper? It might be that there are 2 purchase events triggering and you simply need to delete one. 

However, duplicate conversions from Facebook can happen in many situations. For example, customers that refreshed the checkout page, clicked and/or viewed more than one ad in the attribution window and the list goes on... It's quite a known issue that makes it hard for you to really measure your advertising performance and ROAS accurately.

We developed on AdScale a report that helps you to eliminate the double conversions by connecting the conversion ID directly to the Shopify Order ID, and this can detect duplicate conversions on Facebook  & Instagram, or even cross-platform between Facebook & Google. This way you can get the real picture of your advertising performance!

AdScale is the best way to advertise on Facebook & Google because we use the power of your store data (that they don’t have) to run highly targeted ads and get an average ROAS of 10X.

Check this out:

I basically removed the pixel from the preferences of the theme as I have the pixel set up through the Facebook sales channel and seems to have fixed it.

i highly recommend, first of all talk to Shopify support (i did too). because as many persons raise this same issue to them, they will update their "facebook channel integration" because when we set data sharing settings on "maximum" and allow "Conversion API" technology to help tracking, this issue occurs. and when you remain it standard (only on pixel) this problem will not bother you. Change your settings to "Standard" in facebook channel under data sharing option. and after 1-2 days your pixel issue will be normal.

but the question is, facebook suggesting us diagnose method to for this issue but how we can put that the "code id" into our source code. and it should be an automatic process by Facebook channel in shopify. because we cant change anything behind the channel. so that i told you contact with shopify customer support first.

Hey Gourav,

Thanks for the response.

I am still having issue in my pixel "Serving external ID not matching to pixel external ID".

Hi  

In my opinion this issue is not restrict your targeting or reach, its due to their backend error/issue. I guess it will automatically vanish as they updating their fb channel app. i have similar issue but its okay because its not causing me anything. infect since i change my data sharing setting to Standard my campaign performing well compare to before.

kindly raise this issue to Shopify support.
first login with your account (on which your store has active) Goto this link - Shopify Support  [ go to end of the page] you will find a link for chat to the support - choose your store > and start chat with support executive.
