Shopify Product Management

This flow validates a complete Shopify Admin GraphQL API integration. It authenticates using client credentials, confirms access to the expected store, and lists existing products. It then creates a draft product, retrieves it by ID, updates its main fields, deletes it, and verifies that it no longer exists. The flow also checks GraphQL userErrors, since Shopify may return HTTP 200 even when a mutation fails. Because the product remains in draft status and is deleted at the end, the test does not publish anything or leave test data behind.
