WHAT IT DOES

What decline_return_request does on Shopify Graphql

AI agents use decline_return_request to create or update resources in Shopify Graphql — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Shopify Graphql environment.

WHY IT NEEDS A POLICY

Why decline_return_request needs a policy

Declining a return request modifies the state of a return in the Shopify system (from pending to declined), which is a reversible write action. It does not delete data, execute code, or involve financial transactions directly.
