I have a Shopify site that was recently setup to use the new access token requirement.
After getting past the authentication errors, I am now able to successfully perform a GET request to retrieve a list of products.
What I can’t do is perform a PUT or a POST. A PUT returns an invalid parameter error. A POST says 200 success, but it doesn’t return the new product body. It instead returns the full product catalog but no new item is created.
Oddly enough, when I switch my environment variables to an older sandbox site and make the same requests, everything is working.
All necessary app permissions for what I need to perform with the API have been selected. Cookies have been cleared and I’ve tried two different programs (insomnia and postman). I am at a complete loss as to why the one site is refusing to work.
