  description: "Spree Admin API v3 - Administrative API for managing products, orders, and store settings.\n\n## Authentication\n\nThe Admin API requires a secret API key passed in the `x-spree-api-key` header.\nSecret API keys can be generated in the Spree admin dashboard.\n\n## Response Format\n\nAll responses are JSON. List endpoints return paginated responses with `data` and `meta` keys.\nSingle resource endpoints return a flat JSON object.\n\n## Resource IDs\n\nEvery resource is identified by an opaque string ID (e.g. `prod_86Rf07xd4z`,\n`variant_k5nR8xLq`, `or_UkLWZg9DAJ`). Use these IDs everywhere — URL paths,\nrequest bodies, and Ransack filters all accept them directly.\n\n## Error Handling\n\nErrors return a consistent format:\n```json\n{\n  \"error\": {\n    \"code\": \"validation_error\",\n    \"message\": \"Validation failed\",\n    \"details\": { \"name\": [\"can't be blank\"] }\n  }\n}\n```\n"
