Use Trendtrack with n8n

n8n's HTTP Request node is enough to drive the entire Trendtrack public API. There is no custom node — you authenticate with a Bearer header, hit https://api.trendtrack.io/v1/..., and pipe the JSON into Slack, Discord, Notion, Sheets, Airtable, HubSpot, or any other n8n destination.

This guide gives you:

• A working setup: API key, n8n credential, first authenticated call, credit-budget visibility.
• An endpoint cookbook: one mini-recipe per resource family, with the exact HTTP node configuration.
• A gallery of ten importable workflows covering daily creative monitoring, scaling alerts, shop discovery, email watch, and on-demand brand 360 reports.

Setup

What a healthy first call looks like

curl -s "https://api.trendtrack.io/v1/me" \
  -H "Authorization: Bearer $TRENDTRACK_API_KEY"

{
  "data": {
    "credential": {
      "id": "cred_01HZ…",
      "name": "n8n production",
      "accessLevel": "workspace",
      "createdAt": "2026-04-12T10:22:31.000Z"
    },
    "workspace": {
      "id": "ws_01HZX0W3YJABCDEF",
      "slug": "acme-growth",
      "name": "Acme Growth"
    }
  },
  "requestId": "req_01HZ…"
}

Shell endpoints (/v1/me, /v1/workspace, /v1/usage, /v1/health) are unmetered — they're the safest way to validate authentication and resolve workspace context before running metered loops. See Getting Started for the full bootstrap sequence and Errors for the error envelope you'll match against in n8n's IF nodes.

Endpoint cookbook

Every recipe below is a single HTTP Request node. They are intentionally minimal — combine them with n8n's Set, Function, Split In Batches, and IF nodes to build the complete workflows in the gallery.

1. Discovery — POST /v1/ads/query

Advanced ad search. Use it for niche-keyword scouting, reach thresholds, and date-bounded queries.

• Method: POST
• URL: https://api.trendtrack.io/v1/ads/query
• Body Content Type: JSON
• Pagination: page + limit (max 100); 1 credit per returned row.

{
  "search": ["serum"],
  "searchType": "adCopy",
  "sortBy": "reach",
  "order": "desc",
  "status": "active",
  "minReach": 50000,
  "reachPeriod": "last7d",
  "adsTimePeriod": "last30d",
  "limit": 25,
  "page": 1
}

The response carries { data, pagination, requestId }. pagination.totalPages tells you when to stop a Split In Batches loop.

2. Brand resolution — GET /v1/lookup

Zero-credit identifier resolution. Always call this first when you have a user-supplied brand name, domain, Instagram handle, or Facebook page id and need a stable Trendtrack identifier.

• Method: GET
• URL: https://api.trendtrack.io/v1/lookup
• Query parameters: q (required, 2–200 chars), type (auto | brandtracker | advertiser | shop), limit (1–10).

curl -s "https://api.trendtrack.io/v1/lookup?q=allbirds.com&type=auto" \
  -H "Authorization: Bearer $TRENDTRACK_API_KEY"

The response gives you brandtracker.id, advertiser.id, and shop.id for the matched brand. Carry those identifiers downstream.

3. Brandtracker folders — GET /v1/workspace/folders

Folders group the brandtrackers you track. Several aggregate endpoints accept folderIds to scope a query to a folder (e.g. "skincare clients" vs "supplements clients"). Resolve folder ids once, cache them in n8n, then pass them as repeated query params or a comma-separated list.

• Method: GET
• URL: https://api.trendtrack.io/v1/workspace/folders
• Cost: unmetered.

folderIds is currently honored on /v1/workspace/hooks, /v1/workspace/ad-copies, /v1/workspace/landing-pages, /v1/workspace/media-mix, and /v1/brandtrackers. It is not accepted on the canonical /v1/workspace/top-ads ranking endpoint today — for folder-scoped rankings or rank movers, the recommended pattern is to call /v1/workspace/top-ads and filter the response client-side on brandtracker.folderId. (/v1/workspace/scaling-ads is a legacy compatibility endpoint that still accepts folderIds; new integrations should prefer /v1/workspace/top-ads?sortBy=rankDelta7d + client-side filtering.)

4. Workspace top creatives — GET /v1/workspace/top-ads

Canonical current-ranking endpoint across every active brandtracker in the workspace, in a single metered call. Use it as the spine of any "what's working right now" dashboard.

• Method: GET
• URL: https://api.trendtrack.io/v1/workspace/top-ads
• Query parameters: page, limit (max 100), sortBy, euOnly, includeInactive.
• sortBy values:
  • currentRank — current Facebook page rank.
  • reach, reachDelta1d, reachDelta7d, reachDelta30d — reach rankings (impressions is an accepted alias for reach).
  • rankDelta7d, rankDelta14d, rankDelta30d — rank movers (use these for scaling alerts).

curl -s "https://api.trendtrack.io/v1/workspace/top-ads?sortBy=reachDelta1d&limit=10" \
  -H "Authorization: Bearer $TRENDTRACK_API_KEY"

period and snapshotDate are deprecated on this endpoint and ignored — drive everything from sortBy. See Time windows for the full picture.

5. Hooks, ad copies, landing pages — /v1/workspace/{hooks,ad-copies,landing-pages}

Aggregated creative analytics across the workspace. Same query-param shape on all three.

• Query parameters: page, limit, folderIds (optional, comma-separated or repeated), and endpoint-specific time controls.
• Cost: 1 credit per returned row.

curl -s "https://api.trendtrack.io/v1/workspace/hooks?folderIds=fold_skincare,fold_supplements&limit=20" \
  -H "Authorization: Bearer $TRENDTRACK_API_KEY"

6. Shops discovery — POST /v1/shops/query

Find Shopify-style shops by category, technology, market, traffic, and ad activity. This is the broader cousin of /v1/ads/query — instead of returning ads, it returns the shops that run them.

• Method: POST
• URL: https://api.trendtrack.io/v1/shops/query
• Pagination: offset + limit (offset-based, not page-based).

{
  "search": "skincare",
  "searchType": "productName",
  "sortBy": "activeAds",
  "order": "desc",
  "adsTimePeriod": "last30d",
  "minActiveAds": 10,
  "mainMarketCountries": ["FR"],
  "technologies": ["shopify"],
  "limit": 25,
  "offset": 0
}

Resolve filter values (categories, technologies, pixels, Shopify apps) ahead of time via /v1/facets/* (see recipe 10).

7. Shop intelligence — GET /v1/shops/{shopId}/...

Once you have a shopId (from /v1/lookup or /v1/shops/query), the per-shop endpoints unlock product, social, advertiser, and email history.

• GET /v1/shops/{shopId}/products?sortBy=popularity&limit=10 — best-sellers.
• GET /v1/shops/{shopId}/socials/history?period=day&days=90 — Facebook/Instagram follower time-series.
• GET /v1/shops/{shopId}/similar — adjacent shops to expand prospecting.
• GET /v1/shops/{shopId}/advertisers — Facebook pages running ads for this shop.
• GET /v1/shops/{shopId}/emails?sentAfter=2026-04-01 — recent email campaigns from this shop.

Each endpoint is metered per returned row.

8. Email campaigns — POST /v1/emails/query

Workspace-wide promotional email discovery. Useful for tracking competitor campaigns, sale calendars, and launch cadence.

{
  "search": ["sale", "black friday"],
  "searchType": "subject",
  "keywordMode": "any",
  "shopifyPlan": "plus",
  "minMonthlyVisits": 50000,
  "limit": 25,
  "page": 1
}

9. Advertiser-level discovery — POST /v1/advertisers/query

Rank Facebook pages directly — useful when you want a "most active in my vertical" leaderboard rather than ad-by-ad analytics.

• Sort options: relevance, newest, activeAds, newAds, euAdsShare, reach, reach14d, followers.

10. Facets — GET /v1/facets/{categories,technologies,pixels,shopify-apps}

Zero-credit lookups that resolve human-readable filter inputs to the stable ids that /shops/query, /ads/query, etc. expect.

• Pagination: offset + limit (defaults to 100, max 500).
• Use the optional search query parameter to narrow results before pulling them.

curl -s "https://api.trendtrack.io/v1/facets/categories?search=skin&limit=10" \
  -H "Authorization: Bearer $TRENDTRACK_API_KEY"

Workflow gallery

Each workflow ships as a single n8n JSON file at /integrations/n8n/workflows/<file>.json. Import via Workflows → Import from File in n8n, set the TRENDTRACK_API_KEY environment variable, then connect any destination credentials required by the workflow (Slack, Discord, Notion, Google Sheets, Gmail, etc.) before activating.

The downloadable files are sanitized examples: they are inactive by default, do not include local n8n workflow ids, do not include pin data, and use placeholder destination ids such as C0123456789, YOUR_GOOGLE_SHEET_ID, or YOUR_NOTION_DB_ID that you must replace.

TRENDTRACK_API_KEY=tt_live_...

If you cannot use n8n environment variables, open each Trendtrack HTTP Request node and replace the Authorization header expression with Bearer YOUR_API_KEY.

Folder param contract

Several gallery workflows start from a tracked brandtracker folder. In those workflows, edit the first Set Parameters node and replace folderName = Demo with the folder name you use in Trendtrack.

• n/a — the workflow is per-brand or utility-only; folder scoping doesn't apply.
• Optional folder — defaults to the whole workspace unless you add filtering.
• Mandatory folder — the workflow loops over a Trendtrack folder; set folderName before the first run.

Cost & rate limits

Every metered endpoint consumes one credit per returned row. The relevant headers on every metered response:

• X-Credits-Used — credits consumed by this request.
• X-Credits-Remaining — balance after the call.
• X-Credits-Source — recurring, topup, or hybrid.
• X-Request-Id — quote when contacting support.

A few practical guards while iterating in n8n:

• Start every recipe with limit: 5–10 and only raise it once the workflow shape is stable. A loop bug at limit: 100 burns the workspace.
• Pin a daily budget by reading X-Credits-Remaining in an IF node and breaking the loop below a threshold.
• Pagination is page-based (page + limit) on most endpoints, offset-based (offset + limit) on POST /v1/shops/query and the /v1/facets/* endpoints. Stop paginating when the response returns fewer rows than limit.

See Credits & Billing for the full consumption model and Rate Limits for 429/Retry-After handling.

Going further

The same patterns apply to Make.com and Zapier — both have a generic HTTP module with Bearer auth, identical body shapes, and similar pagination handling.

For agentic workflows (LLM calls that browse the API live), point your agent at the Trendtrack Agent Guide — it carries machine-friendly summaries of every public endpoint, the enum cheatsheet, and the canonical agent traps to avoid.

FAQ

My calls return 401 missing_api_key from n8n but curl works. Double-check that the Header Auth credential header name is Authorization (not X-API-Key or Authorization-Bearer) and that the value is Bearer <key> with a space, not just the key. n8n trims newlines but not extra prefixes.

How do I paginate cleanly? Use a Split In Batches loop with the page index, increment until pagination.totalPages is reached, and break early when the returned data.length < limit. For /v1/shops/query and /v1/facets/*, increment offset by limit instead.

I'm hitting 429 rate_limited. Read the Retry-After response header and feed it into a Wait node. Public endpoints are tiered (heavier endpoints have lower per-credential rate caps); see Rate Limits for the exact tiers.

What's the difference between /v1/brandtrackers/{id}/... and /v1/workspace/...? Brandtracker endpoints scope to a single tracked brand. Workspace endpoints aggregate across every active brandtracker in the workspace in a single metered call — preferred whenever you'd otherwise loop over brandtrackers and concatenate the results.

Can I filter /v1/workspace/top-ads by folder? Not natively today. The recommended pattern is to call /v1/workspace/top-ads and filter the response client-side on brandtracker.folderId — applies to current rankings (sortBy=currentRank/reach) and to rank movers (sortBy=rankDelta7d/14d/30d) alike. The legacy /v1/workspace/scaling-ads endpoint still accepts folderIds if you need server-side filtering today, but new integrations should standardize on /v1/workspace/top-ads.
