# Trello

Trello provides OAuth1 support for their authentication process.

In order to enable it, follow:

- Generate an Application Key pair at Trello Developers API Keys

- Fill Consumer Key and Consumer Secret settings:

      SOCIAL_AUTH_TRELLO_KEY = '...'
      SOCIAL_AUTH_TRELLO_SECRET = '...'

There are also two optional settings:

- your app name, otherwise the authorization page will say “Let An unknown application use your account?”:

      SOCIAL_AUTH_TRELLO_APP_NAME = 'My App'

- the expiration period, social auth defaults to ‘never’, but you can change it:

      SOCIAL_AUTH_TRELLO_EXPIRATION = '30days'
