How to validate Webhooks?

When your webhook secret is set, Conscent uses it to create a hash signature with each payload. This hash signature is passed with each request under the X-Conscent-Signature header that you need to validate at your end.

Nodejs

var crypto = require('crypto');

var hmac = crypto.createHmac('sha256', '<WEBHOOK_SECRET>');

//passing the data to be hashed
rawBody = '<RAW_BODY_OF_REQUEST>';
signature = hmac.update(req.body).digest('hex');

//Printing the output on the console
console.log('hmac : ' + signature);

// NOTE: try matching `signature` with request header `x-conscent-signature`

Do Not Parse or Cast the Webhook Request Body

While generating the signature at your end, ensure that the webhook body passed as an argument is the raw webhook request body. Do not parse or cast the webhook request body.
