WHAT IT DOES

What complete_checkout does on Shopify Graphql

AI agents use complete_checkout 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 complete_checkout is rated Medium

While it involves financial implications (the draft order represents a potential purchase), it does not directly move money or commit financial obligations—it merely prepares an order for processing.

From the tool's definition Tool name 'complete_checkout' and description 'Convert an abandoned checkout to a draft order' indicates creating or modifying a draft order object in Shopify's system.

complete_checkout Rate-limited

complete_checkout stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
