title: How do I access the raw body of a Fastify request?
body: <p>As you may imagine, I'm familiar with Express, but this is the first time I'm using Fastify.</p>
  
  <p>I'd like to access the <em>unmodified</em> body of a Fastify request, for signature verification of a webhook - ie, I would like to see the request as it came in, unmodified by any middleware. In Express this is often done by accessing <code>request.rawBody</code>. </p>
