2FA err when connecting to shopify API

Im usin “Get many orders” node and I’m trying to connect the API with OAUTH2

I tried it on my dev store and everything works just fine, but when I tried it on a real shop, I get this error:

I did everythin the same..
Both shops don’t have 2FA, also I tried with and without 2FA and the err stay the same
I even tried to add 2FA to n8n but it didnt help
The app is 1-2026 version

Has anyone encountered this before?
Thanks

im not sure but i think the issue might be related to the 1-2026 version of n8n and shopify api connection. have you checked if there’s any recent updates or changes in the documentation that might affect your setup? specifically, have you tried checking the shopify oauth2 settings in the n8n app to ensure they match what’s required for the “Get many orders” node? let me know if that helps!

Hi @Amit_El_Al,

Have you tried to use an Access Token or API key instead of Oauth?

it works perfectly for me when I connect the node to my Dev Shopify Shop, but when I tried it on a Real Shopify Shop, it didn’t work and returned me the err above, so I dont think its implementation problem, maybe a configuration problem?

tried both but without success

Did you create a new app in shopify and auth credential in n8n for the retail shop? You need to set the shop sub domain which would be unique to the shop you want to connect to
