How to use OAuth 2.0 with trello

[Ayush Mishra]

I am using https://trello.com/1/authorize?expiration=1day&name=MyPersonalToken&scope=read&response_type=token&key={YourAPIKey}

after authorize the consent it will redirect to the/token/approve route but not in /callback.. Please help how can i proceed?

but if i use return_url then it works fine.. I was not able to find any code in callback query  but it returns the token itself..

Hey @Ayush Mishra - Trello's API does not support OAuth 2.0 currently.

The API supports OAuth 1.0 and there is documentation on how to authorize clients here: https://developer.atlassian.com/cloud/trello/guides/rest-api/authorization/

@Felix I'm trying to implement OAuth 1.0 and it says that I can access my API key by logging into Trello and visiting https://trello.com/app-key/. However, even though I am logged in, the url returns a 401 error. How can I access my API Key?
