According to the twitter API form, oauth1 clients should specify the callback URL when they request a token. Meteor’s oauth1 package gets the redirect URL from the service configuration, so as long as you’ve specified it when configuring the first time connection form I think it should work.
I maybe able to elave the callback url empty.(didnt understand what u wrote)
but i still get
Error
The client application failed validation: Not a valid URL format.
