Facebook Pixel Error: Server External ID Not Matching to Pixel External ID for Purchase Event

[lorenzopohl]

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?

Does anyone use Zipify OCU app? Wondering if that's causing it.

I'm waiting on Shopify as well. We're building out a custom checkout page in the meantime.

[stccompanyalwar]

No we are not using Zipify App. We are trying to host in other platform as nothing is working.

Shopify sent me an email today:

"Our developers and the team at Facebook have definitely noticed a large increase in these errors, and it appears to be due to an updated implementation in Facebook's CAPI version 2.

We have heard back from Facebook, and they have noted that these errors will not be impacting Pixel performance on your store. As well - they have notified us that Facebook has removed the new instances of this error related to External ID not matching. Can you please review your Facebook Pixel, and let us know if you're seeing any new instances of this error? The error may still exist historically in the data of your Pixel, but going forward Facebook has mitigated this issue."

Today stats are the same, shitty as they were, no atc, no purchase data, half the view content. 

I ignored the errors, will see.

Anyone seeing normal stats? Shopify claims this was fixed but my stats are still really low.

See below...

We've confirmed information from our developers about the warning that you are receiving in your Data Sources section. Merchants who use the Maximum data-sharing level  are seeing this because we have rolled out a new version of the Conversion API used by Facebook. The Conversion API  now sends the six standard pixel events between Shopify and Facebook servers in addition to javascript via the browser. Previously, we were only sending the purchase event in this manner.

In preparation for this, our developers pushed out some changes and they triggered the Pixel warnings you have seen in your Event Manager. Our developers have confirmed with Facebook that these changes weren't affecting the existing Pixel events that are being sent via browser or the purchase event being sent via server. Facebook has also confirmed that they have prevented these warnings from appearing again so you can dismiss them by clicking Mark as resolved in your Event Manager and the warnings won't reappear.

very shitty sales , states very bad. Nothing is normal

[BP-Shop]

Do you have MAXIMUM MATCHING on for facebook pixel settings?

Looks like that could be causing the issue since it's new.

I changed the settings to ENHANCED MATCHING to see if that'll make a difference as a temporary solution.

[Benny2002002002]

Yes I do have maximum setting on. I thought enhance setting would limit the amount of customer which result in lower sales isn’t it?

[stccompanyalwar]

Is there any luck as we are still not getting any sell. Our pixel was 1 year old all setting was done properly it was tracking everything fine prior to 15 th June.

[BP-Shop]

I tried both "enhanced" and "maximum" and purchase events seem off with both. Really frustrating

[stccompanyalwar]

Same for us. Also checked with other paid app. Only session getting created no improvement in conversion.

[dmitrybzns]

I do get sales, and no errors but checking data is almost impossible. Today out of 6 sales I only see 2 in FB ads manager. While UTM's show that all 6 came from Fb ads.

I assume if pixel sees only 2 sales then it doesn't take other 4 into the optimization.

I also checked operating system this sales came in, and Android sales also not being counted.

Things seem to have gone quiet on this for a week or so now. I'm currently experiencing these issues too in event manager. Anyone have any updates?

[Steven_Gross]

Did this ever get resolved? It just seems like there are a lot of open tickets around this topic...

[Steven_Gross]

Here's another thread that's still open on this - https://community.shopify.com/c/Shopify-APIs-SDKs/ALERT-Server-External-ID-Not-Matching-to-Pixel-Ext...

[Derelicte]

I just started having this issue this week 😞

[Halo123456]

Hi, were you able to resolve this? Mine comes and goes away and then it finally came back and stayed that way.

[Spartanc]

Hi all,

I just started to have this problem yesterday.

If anyone has any updates please share.

Thanks!

I also got this error only today. Even though I had customer purchases and the purchase event detected them, I am not able to view this data in my ad campaign and it's difficult to attribute the purchases to a specific ad set!

I don't know if this is related to the error but I'm assuming it is.

is there an update on this issue?

[MORE10]

Hello how does this issues working out?

[revoplus]

Also having this issue on one of our stores now, for all of our events. Any solutions? Shopify Plus support said everything is OK with their API so  only solution is to post on the forum.
