What create_gift_card does on Shopify Graphql
AI agents use create_gift_card to commit financial operations through Shopify Graphql, usually the final step of a payment, billing, or trading workflow. A call moves real money.
Why create_gift_card is rated Critical
Creating a gift card issues a financial instrument with real monetary value. If misused, an AI agent could create large numbers of high-value gift cards, resulting in significant financial liability for the merchant. This clearly falls under the Financial category as it commits financial obligations.
From the tool's definition "Create a new gift card" — gift cards represent stored monetary value and committing a new gift card is a financial obligation for the merchant
