Hi, not sure what im doing wrong, but the merchant center lookup doesnt return my enriched items from merchant center , only my items array from the datalayer.
screenshots from the setup
Thank you!
Hi!
Do you see a request to https://shoppingcontent.googleapis.com/content/v2.1[...] being made on GTM Preview Mode?
This is the request that is triggered by this variable to get data from the Merchant Center.
no i dont see any outgoing request and i dont see anything in the log either.
Stape support told me that no authentication in cloud console is needed, and its just plug and play - but im unsure if this is true?
If you try running the template code via GTM UI, what logs do you see? Like this.
Follow up questions:
- Is the Contents API enabled on your GCP Project?
- Have you connected the Service Account of your GCP Project where the Contents API is enabled to Stape?
- Have you added the Service Account as an admin to the Merchant Center account?
Thank you for reply!
Running the test, im just getting "variable value: undefined
I did enable the API, and i did make a service account added it in Stape store as well.
I also added the service account email to Merchant center under users and gave it admin access.
I also a screenshot of the datalayer of the items array.
So the value of the “item_id” in datalayer is not the same as the item id of products in Merchant Center. The actual product ids in merchant is the value of “item_sku” in the datalayer - I dont know if that could be the problem perhaps?
Hi!
It looks like you have checked all the requirements (enabling the API, Service Account etc.).
Running the test, im just getting "variable value: undefined
I think this is happening because you are referencing the {{ED - Items}} variable in the Template Preview pane. This variable will return undefined because the Event Data is empty when testing via this screen.
Just for testing purposes, you can create a copy of this template and play around with it. Try replacing the values of the items variable on the line 19 to the array you sent on your first screenshots.
This way, you can get a sense of how the request behaves.
// Change from
// let items = data.items;
// to
let items = [{ item_id: '9732134928706', item_sku: '90PK05', /* ... */ }]
So the value of the “item_id” in datalayer is not the same as the item id of products in Merchant Center. The actual product ids in merchant is the value of “item_sku” in the datalayer - I dont know if that could be the problem perhaps?
Most certainly. The variable uses only the item_id as key for searching the products in Merchant Center. Therefore, if the values that should be used are in a different key, nothing will work.
For now, you can change the template to suit your needs.
I’ll put this change (the possibility to choose where to get the ID from: item_id, item_sku etc.) on our backlog, so that everyone can use it.
By the way, I noticed that your screenshot of APIs and services shows an error for the Content API for Shopping. What do you see when you click on it? It should say what kind of error is happening (response codes, which API methods, which credentials etc.).
Thank you for helpful reply, really appriciate it!
So i tried changing the code at line 19 to your code, and now it works when i run a test - so i guess the problem is that my product id’s in merchant center are from item_sku in my datalayer, and the variable uses item_id.
Can i perhaps you for a line of code that i can use, so it pulls from item_sku instead? 
Its fair if im asking for too much, but atleast we figured out the problem!
Sure! Please note that this is an unofficial modification of the template and is not officially supported or maintained. Use it at your own discretion, as it won’t receive future updates or bug fixes.
Update all references of item.item_id to item.item_sku on lines 26 and 34. It should start working 
.
Thank you for very good support - it fixed everything !
Would be nice to get it added to the offical one as well.

Totally. It’s already in our backlog.
