Hygraph Utils

Install

npm i @graphcms/utils

Usage

verifyWebhookSignature

const { verifyWebhookSignature } = require("@graphcms/utils");

const secret = "rCNwyiloY3oJYYkxgpBXaleIiUv5MYlx";

const body = {}; // Typically req.body
const signature = "..."; // Typically req.headers['gcms-signature']

const isValid = verifyWebhookSignature({ body, signature, secret });

verifyWebhookSignature also accepts a rawPayload in the case that the body has not yet been parsed.

const { verifyWebhookSignature } = require("@graphcms/utils");

const secret = "rCNwyiloY3oJYYkxgpBXaleIiUv5MYlx";

const rawPayload = '{"hello":"world"}';
const signature = "..."; // Typically req.headers['gcms-signature']

const isValid = verifyWebhookSignature({ rawPayload, signature, secret });
