Hi there,

I know this is more on the facebook site but i hope someone can help me since i am not getting the same data in shopify than i get in facebook for my ad campaigns.

The Facebook Pixel says there is this error on the purchase event:

Any ideas on how to fix this problem and if this is related to my facebook ads data not showing up correctly in the marketing section in my shopify account?

@okimaslatt Nope! It means that Shopify successfully sent Facebook the conversion data and Facebook discarded it all and showed 0 conversions.

@mediacom  8 events, 5 discarded so far.. Now I'm wondering if Facebook is rejecting these because they've matched the sales to users who have not consented to tracking.. wondering if anonymized conversion data would help. Obviously it'd be worse for optimization if the conversions can't be matched to a user, but certainly would be better than missing half the conversions entirely. Can try to make up for it with lookalike custom audiences from sales..

boys let's keep all the discussion in a single thread, and since reddit has a better UI i recommend visiting this newly made thread below.. dont panic, every single one of us is losing money because of this

Apparently someone on reddit was told Shopify said they would fix it by June 30th.

I got an email from them saying shopify will send all main events with server side, BUT why not to make a hot fix or something. So freaking stupid when they blame it in each other.

Shopify Plus support communicated that they're looking into the problem. Went into my events manager this morning and the 8 warnings on the events are gone! Almost back to normal!

I was facing same error till day before yesterday. Entire 22-June-2021 I have not received that error. But still sell gone down to 30% of the actual value. The Event matching quality is very low. Not sure when Shopify and Facebook will work on proper fix. Right now very less conversion events are fired.

Yesterday the errors were all fixed. However, when I check today atc error appears again. I find that the sales still down even though things are fixed. Their system is completely messed up now.

I think there is no hope. So need to quickly have to switch to other platform. Almost 10 days with no help. Even though the error is not coming now but no conversion.

I am planning to switch. Practically no hope.
