storeCode for Local Inventory Ads

[tschoffelen]

Hi there!

I'm trying to set up Local Inventory Ads (through the API, but facing the same issue in the Merchant Center).

I'm getting stuck on the message StoreCode is missing or invalid. for every request I issue:

I've tried every format for the store code I could think of, including the one listed on the 'Business locations' page where I imported my Google business listing, but none work.

Any ideas why this might be?
