connect-dwolla-webhook When adding support for Dwolla's Webhooks, it's a good idea (read: MUST) to check the validity of the request to ensure that it's actually from Dwolla. This simple middleware for connect does just that. Example var connect = require('connect'), connectDwolla = require('connect-dwolla-webhook'); var app = connect() .use(connect.bodyParser()) .use(connectDwolla({ secret: 'my-dwolla-app-secret' })) .use(function(req, res){ res.end('Hello Dwolla!\n'); });
