I have a Google Docs Spreadsheet that I\'d like to use to update referenced cards in Trello. I\'ve had some success with oauth and pulling data via their HTTP API, but am stuck
In order to get write access, you need to change the authorization url. This example works for me
var oauthConfig = UrlFetchApp.addOAuthService("trello");
oauthConfig.setAccessTokenUrl("https://trello.com/1/OAuthGetAccessToken");
oauthConfig.setRequestTokenUrl("https://trello.com/1/OAuthGetRequestToken");
oauthConfig.setAuthorizationUrl("https://trello.com/1/OAuthAuthorizeToken?scope=read,write");
