Hi All, 

I'm making private app to apply auto discount code into checkout. But i was got issue and stuck on it.

First,i created webhook listener checkout update to receive checkout info.

After that i get id from checkout info and then use graphQL to call checkoutDiscountCodeApplyV2 but alway got error "Checkout does not exist"

Can Anyone help me resolve this issue. Thanks a lot!

Hey @truongnd, from my understanding you can only use a mutation like this on checkouts created by your private app, with the Storefront API - more info here.

@awwdam Do you know what the message "Checkout does not exist" or code "INVALID" means? I am getting the same error when using the JS Buy SDK and I can't figure out what is causing the issue.
