1. Server external ID not matching to pixel external ID
This error typically occurs when the external ID for a Facebook pixel on your Shopify store does not match the external ID for the same pixel on your Facebook account.


To resolve this issue, you will need to ensure that the external ID for the pixel on your Shopify store matches the external ID for the pixel on your Facebook account. This can typically be done by going to the Facebook Events Manager, finding the pixel in question, and comparing the external ID listed there to the external ID on your Shopify store.


If they do not match, you will need to update one or both of them to ensure that they are the same.


2. Redundant purchase events
This error typically occurs when multiple purchase events are being sent to Facebook for the same transaction. This can happen if you have multiple pixels installed on your website, or if your purchase event tracking code is being triggered more than once on a single transaction.


To resolve this issue, you will need to identify and remove any redundant purchase events that are being sent to Facebook. This can be done by reviewing your website's code and removing any unnecessary tracking codes, or by disabling any redundant pixels.


Additionally, you can check the pixel's setting on your Facebook Event Manager, there is an option to turn off duplicate purchase events.


3. Missing Purchase currency and value parameters
This happens when the purchase event code on your website is not properly passing the currency and value of the transaction to Facebook. This information is required for Facebook to properly track and attribute the purchase to your ads.


To resolve this issue, you will need to ensure that your purchase event code is passing the correct currency and value parameters for each transaction. This can typically be done by reviewing the code on your website and verifying that the correct parameters are being passed to Facebook.


You can check the pixel's setting on your Facebook Event Manager, check if the currency is set to auto-detect or you set it manually, and also check if you are passing the correct value of the purchase.


If you are using an app to track your purchase events, you should check the settings and make sure that the currency and value parameters are set correctly.


If the problem persists, you can contact Shopify support or Facebook support for further assistance.

I'm experiencing these exact issues. They started on the 17th of this month. I didn't touch or change anything. Hopefully they get resolved soon. 

 

Here is another thread reporting the same thing.
