Products not publishing to Google- Shopify asking for GTIN or MPN but I have already provided a GTIN

so the issue I had was that the below field would be blank, even though I had it marked in the actual product. For small stored I manually had to set it to true (if there was no GTIN) or Falso (if there was a GTIN).

But This did it for many stores that had 1000’s of products so going through and changing each manually wasnt an option. So I ended up downloading Google Feed for Shopping by Symprosis which has a 21 day free trial to test and this sorted my issues perfectly. So its definitley the Google Channel apps issue not merchant centre, but Shopify doesn’t want to acknowledge it.

For all my high performing stores I just migrated over to the paid version of the app (which provides alot more functionality).

They still show as needing a GTIN in the hopify app (which is stupid) but in merchant centre they are fine.

I appreciate this is an old thread but now I am experiencing the same issue after a year of everything being fine. When you say google requires you to have the correct format for GTIN codes what do you mean exactly?

You: Google requires the correct format for GTIN or MPN; in case you have the correct format, it shows missing GTIN.

Thanking you in advance

Hi,

I stopped using the shopify google app and went over to a paid app instead. The costs aren’t that high for my shop (60k+ products) and it’s definately a better app than the one shopify provides. The one I use is called ‘Feed for google shopping’. You should check it out, because I dont think shopify will fix this issue any time soon. It also has a 21 free trial period, so you can have your sales going in the meantime.

Regards,

Kevin

You mentioned you bought your own barcodes, I have left you the correct answer based on that statement.

Same issue here, having spent hours on live chat to both Google and shopify I’m at my wits end. Shopify can’t seem to rectify it, looks like the best option is to move to another app to sync shopify products with Google. A great shame :disappointed_face:

@LEPUP the solution to barcodes not submitting, is to go to Shopify > sales channel > google > manage availability > change custom products to the value false.

I think I it is pointless wasting time with google or Shopify team. I tried today as well over an hour again! With Shopify! They don’t seem to get it. I pointed out that the number even goes up or down (or unpublished items) and there are also issues on the merchant account I cannot fix. Went though it manually and they suggested to Change the title briefly and save it and then it was solved but minutes later error came back! What a shame! So Shopify has to figure this out but won’t. Does this impact the google search or shipping campaign anyone knows? I wonder if it does! If so then I immediately go to a paid app if that is any better. I can’t tell if google now published or is this just a glitch showing it wrong…

If I do as you say and set custom products to ‘false’, then it will ask me for a barcode/GTIN/MPN… which I do not have because these ARE custom products. The solution is to put custom products as ‘true’ and then you do not need a GTIN/MPN. However, this doesn’t seem to work and the problem is the connection between Google merchant Centre and Shopify which seems to be broken. If you go into Google merchant centre and manually force a sync, occasionally some of the products will publish but not all of them… And within a couple of days they revert back to being unpublished. The problem is with Shopify, it’s something that you need to fix. So fix it.

Hi everyone , I’m not really following this conversation anymore but a few of us had another discussion on this topic about 4 months ago - https://community.shopify.com/c/shopify-discussions/urgent-help-gtin-missing-google-unpublished-products/m-p/1411655#M270300%3Futm_source=communitymembers&utm_medium=email&utm_campaign=mention

. This is what resolved my issues finally - it’s simple so you may want to try it.

I posted earlier that Shopify got in touch and told me this:

This is John from Shopify Specialist Support, I’m checking into the issues you are having with the Google Channel at the moment.

The majority of disapproval warnings I am seeing seem to be related to Image crawl issues rather than missing GTIN’s at the moment. I have tried to refresh the feedback on your available products to see if that will provide you with more accurate errors.

Can you please make sure the following setting on your Google Merchant Center is disabled exactly as outlined below.

• Navigation Google Merchant Center > Tools and Settings > Automatic Improvements > Item Updates. If it has been enabled it must be disabled.

It is a simple step but it has resolved my GTIN issues on Google Merchant (they are still showing rejected on Shopify but not on Merchant).

I do have a problem with 4 variants being rejected due to ‘price’ now - they are set up correctly so now Shopify are looking into this. At least tho its gone from 221 issues down to 4.

You might want to try this simple change.

Yep I’ve done that too in Google merchant centre and it helped publish a
handful of my products for 2 days and then they reverted back to
unpublished. My issue is definitely with GTIN on my custom products and I’m
not the only person with this issue. The problem is with the shopify link
to Google merchant centre. Shopify needs to rectify it as it is affecting a
lot of sellers.

Hey did anyone ever get a solution? I am having the same issue with error ’ You need to add a gtin or mpn.’ I have set them to custom and even put data in the MPN field? but getting an error to say that I havent added it?
