WHAT IT DOES

What update_payment_terms does on Shopify Graphql

AI agents use update_payment_terms 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.

RISK

Why update_payment_terms is rated Medium

Updating payment terms is a reversible write operation that modifies financial agreement conditions on orders or customers. While it touches financial data, it does not move money or commit financial obligations directly — it only changes the terms under which payment is expected. However, misconfiguration could lead to incorrect billing terms being applied broadly, hence high severity.
