Trello - 401 authorization failed

Basically, Trello removed the “API connection” to unify it with Power-Ups.

Since then, it never connects.
It is a mistake that has been going on for 3 months.

The n8n version is (and was) always the LATEST DOCKER image.
Database default.
Everithing is defaults.
O.S. Ubuntu
Running a self host, with https

It looks like your topic is missing some important information. Could you provide the following if applicable.

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

The n8n trello docs is outdated

and the Trello API Key portal does not exist any more

Finally the Client Secret token didn’t work, so I had to generate a Secret Token for my specific user.

The link is,write,account&response_type=token&key={{POWER_UP_API_KEY}}

Where you get the new access token… And it works.

Note: I previously added the Power-Up to each board. I don’t know if this is necessary.

If you need help writing the document, answer my thread.
