Custom appsAPIGET /oauth1

The GET /oauth1 endpoint performs the initial setup for OAuth version 1 accounts. Included with the request is a single query argument, callback_uri, which is the redirect URL that the user should be expected to be redirected to upon successful authentication with the third-party service. Return body should at least include a redirect_uri that the user should be forwarded to in order to complete setup. Replies are then POST'ed to this endpoint.

// GET /oauth1
{
    "redirect_uri": "https://trello.com/1/OAuthAuthorizeToken?oauth_token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx&name=TrelloIntegration"
}

Note: The OAuth implementation requires the account identifier to be oauth for OAuth version 1.
