Shopify Discount Code does not work in headless site

Shopify Discussion

Hi all,

I am adding new codes to try and test some features in our headless site however i cannot get any of them to work. They work in the out of the box shopify checkout but for our own custom checkout they turn up as “invalid or expired”

I checked the endpoints for our graphql calls and they seem to match. Any ideas?

I’ve noticed its only with the free shipping discounts it does not work!

When calling the backend graphql service using

updateCartDiscountCodes

No matter what if its a free shipping code it returns as appicable: false

Don’t know how to move past this
