We check Trello's listed URL (https://developers.trello.com/) once a day. History started when Trello was first checked, so new entries show fewer than 30 days.

Trello API not working for you?

  1. Trello needs OAuth. A 401 or 403 usually means a missing, expired or mis-sent credential: check whether it belongs in a header or the query string.
  2. A 429 response means you're being rate-limited. Slow down, cache responses, and respect any Retry-After header.
  3. If calls fail only in the browser with a CORS error, Trello may not allow cross-origin requests. Call it from your server instead.
  4. If it works from one network but not another, check firewalls, VPNs and regional blocks.
  5. Check the provider's documentation, status page or social accounts for planned maintenance or a changed endpoint.

Trello API status FAQ

Is Trello API down right now?

Trello answered our last daily check (Oct 24, 2026, 12:25 UTC) in 1090 ms with HTTP 200. This page also runs a live check from our server when you open it, so you can see whether Trello is responding at this moment.

How do you check whether Trello API is up?

Once a day our checker requests Trello's listed URL (https://developers.trello.com/) and records whether it answers within 15 seconds. Answers like 401 (needs a key), 403 (blocks bots) or 429 (rate-limited) count as up, because the server responded. The listed URL is often the documentation page, so an API endpoint can occasionally fail while its docs stay up.

What can I use if Trello API is down?

Free Business APIs that were up at their last check include Legal Sandbox Georgia, Verif Entreprise FR, KontragentPro. See the full list of Trello alternatives for a comparison.

Why does Trello API work for others but not for me?

Trello needs OAuth. A 401 or 403 usually means a missing, expired or mis-sent credential: check whether it belongs in a header or the query string. A 429 response means you're being rate-limited. Slow down, cache responses, and respect any Retry-After header. If calls fail only in the browser with a CORS error, Trello may not allow cross-origin requests. Call it from your server instead.
