Securing Twitter Webhook












1















As mentioned in Twitter Docs
Steps to validate a request




  1. Create a hash using your consumer secret and incoming payload body.

  2. Compare created hash with the base64 encoded x-twitter-webhooks-signature value.


Here is my code for doing so:



const buffer = Buffer.from(JSON.stringify(ctx.request.body))

const expectedHash = crypto.createHmac('sha256', TWITTER_CONSUMER_SECRET).update(buffer).digest('base64')


The x-twitter-webhooks-signature header from twitter and the hash generated does not match. Also, the post at https://twittercommunity.com/t/validating-the-webhook-signature-header-in-node-js/102525 says that it's JSON.stringify() issue. I'm using koa and koa-body, how can I fix the hash mismatch?

          Found a solution. Used koa-bodyparser instead of koa-body then sha256 of ctx.request.rawBody matches with the header.
