This product is under the AWL and you should take that into consideration before using it.
Note: The token is kept inside the Dropipe.app, so if you want to have two instances of Dropipe for different workflows, just copy and paste (and rename it if you want). To reset the token, just delete Dropipe.app/Contents/token.txt.
