Probleemoplossing

Every API error returns the same envelope. Always parse error.code, not the human message:

{
  "error": {
    "code": "missing_api_key",
    "message": "Missing API key.",
    "requestId": "req_123"
  }
}

If you need to contact support, include the X-Request-Id response header (or the requestId field) — it lets us correlate your call with backend logs instantly.

401 — Authentication failed

missing_api_key

The Authorization header is missing or empty.

• Check that you are sending Authorization: Bearer <key> (not x-api-key, not Api-Key).
• Verify your HTTP client isn't stripping custom headers. Some CLIs need --header escaping.

invalid_api_key

The header was present but Trendtrack could not resolve it to a key.

• Copy the key again from the workspace API settings — whitespace at either end breaks matching.
• Confirm your base URL is https://api.trendtrack.io unless your TrendTrack contact gives you a different origin; avoid preview URLs.

credential_not_found / credential_revoked / credential_expired

The key resolved but is no longer usable.

• Rotate the key in Trendtrack → Workspace settings → API.
• If this happened unexpectedly, check whether another teammate revoked the key.

402 — insufficient_credits

The request was authenticated but the workspace does not have enough credits for the requested work.

• Call GET /v1/usage to see the remaining balance. It is unmetered but still returns X-Usage-Cost: 0, X-Credits-Used: 0, and X-Credits-Remaining; metered calls may report X-Credits-Source as recurring, topup, or hybrid.
• Top up from the webapp billing page. The fixed rate is $1 = 1,000 credits, minimum top-up $10.
• Remember: cost is charged per returned row, not per request. Paginating with a smaller limit reduces each call's cost.

403 — Workspace or permission denied

workspace_public_api_disabled / workspace_public_api_suspended

The workspace itself cannot call the API right now.

• Ask an admin to explicitly enable Public API access in workspace settings. If no workspace_public_api_access row exists, TrendTrack treats the workspace as disabled.
• Contact support if the workspace was suspended.

forbidden

The credential is valid but not allowed to reach this resource or action.

• Confirm the endpoint is exposed on the Public API (not every webapp endpoint is).
• Check workspace-level role requirements — some resources are admin-only.

404 — Not found

The path exists in the docs but the server does not have that record.

• Verify IDs (adId, shopId, etc.) — a trailing newline or wrong casing often masquerades as 404.
• For collection endpoints, 404 typically means the resource is not in your workspace's scope.

429 — rate_limited

You hit the public rate limit.

• Respect the Retry-After header before retrying.
• Back off exponentially if retries keep getting throttled.
• See Rate Limits for the full model.

500 — internal_error

Server-side failure. This one is on us.

• Include the requestId in any support message.
• If a retry with the exact same payload succeeds, the error was transient. If it keeps failing, reach out.

Request shape surprises

• GET /v1/ads fails or returns a validation error — add the required search parameter, for example /v1/ads?search=skincare&limit=25. For advanced filters with no text term, use POST /v1/ads/query.
• Advanced /query endpoint ignores your filters — send Content-Type: application/json and put filters in the JSON request body. Query-string filters are for the lightweight GET endpoints only.
• Empty collection returned but you expected results — check that filters (status, platform, mediaType) are not narrower than intended. Start with the minimal query, then add filters one by one.
• Fewer rows than limit — that's the end of the collection for the current query. Stop paginating.
• Response missing a field you saw before — schema changes are additive. If a field disappears you think is stable, it likely was renamed or moved into a nested object. Check the API Reference for the current shape.

Still stuck?

• Keep Errors open for the full code list.
• Capture the X-Request-Id and share it with support along with the exact URL and a sanitized copy of the request body.
