The response is a **JSON array**;\n`.[0].data.` holds the payload. Ready-to-run bodies + `jq` recipes are in\n[`references/graphql-queries.md`](references/graphql-queries.md).\n\n## The three operations\n\n| Need | Op | Root field |\n|------|----|-----------|\n| Search / browse a city's deals | `BrowseDealFeed` | `.[0].data.browseDealFeed.cards` |\n| One deal's full detail (options, price, reviews, fine print) | `getDeal` | `.[0].data.getDeal` |\n| Category taxonomy | `GetMainNavigation` | `.[0].data...` |\n\n`division` is a Groupon **city slug** (`new-york`, `chicago`, `syracuse`, `los-angeles`, …).\n`dealId` for `getDeal` is a deal's **permalink slug** = the last path segment of a\ncard's `.url` (`https://www.groupon.com/deals/`).\n\n## Two failure modes\n\n- **Empty / non-JSON 2xx** → almost always a challenge interstitial; retry, don't `JSON.parse` it blind.\n- **`{\"errors\":[{\"message\":\"PersistedQueryNotFound\"}]}`** → the baked `sha256Hash`\n went stale (Groupon redeployed its frontend queries). **Re-capture it:**\n 1. Open a Groupon search page in a signed-in-or-not browser, DevTools → Network.\n 2. Filter for `mobilenextapi/graphql`, click the request whose payload `operationName`\n matches the one you need.\n 3. Copy `extensions.persistedQuery.sha256Hash` from the request payload and replace\n the stale hash in `references/graphql-queries.md`.
