Google Merchant local ads [link_template] string attribute

I am having difficulty getting the [link_template] entry correct for Google Merchant Local Feed. I have verified that the setup on my site and Google Business is 100% correct and the listings do show on my Google Local Business page. I feel that I must be making errors in the [link_template] metafield definition. Below is my latest entry, I would appreciate any input as to where I am making an error.
Thank You

Current [link_template] Definition:
https://www.hometimemarketplace.com/checkout/id?={{item_id}}store={{store_code }}

The purpose of the link template for local ads is to have a merchant hosted local storefront. This link, can not be pointing at the checkout.

It has to point at the product landing page. Where you have a system in place where you use the store code, to localize your availability.

Meaning if you have two businesses, one store code is 1111 and another 2222.

If Google sends a user that is located in zone 2222, it will then append 2222 to the URL, and on the product landing page you need to then show the availability for the local store for 2222.

Setting up a local hosted store is very complicated, and if you don’t have a developer to help you, i recommend you only use the Google hosted store version.

Thank you, In my haste I pasted the wrong url lol. I got the link_template working now.
I am having issues with my [checkout_link_template] though, Google says it is correct, Shopify says it isn’t however they don’t tell me anymore than that. The link entered is [https://www.hometimemarketplace.com/checkout?id={id}] When I test it as well as when it appears on a listing it doesn’t work, it starts to load the checkout on Shopify then goes to the home page. Would you happen to know what may be causing this? I have tried every combination that I can think of including adding quantity, storefront etc.
I would appreciate any help as this is the very last thing I have to do on Google Merchant.

It should be https://www.hometimemarketplace.com/cart/123456789:1

Where the 123456789 is your product variant id.

And if you are doing this in the GMC UI it’s https://www.hometimemarketplace.com/cart/{id}:1

Assuming you are using the default Shopify ID, if you don’t use this, it will not work and you need to set it in the data feed.

But I would not do this, you will see your sales tank from free listings.
