## Summary
Follow-up to #20061, which added `rawBody?: string` to
`LogicFunctionEvent` / `RoutePayload` so logic functions can verify
HMAC-style webhook signatures (GitHub's `X-Hub-Signature-256`, Stripe,
…) against the exact bytes that were received.
That PR did not update the public SDK docs, so the new field is
effectively invisible to developers consuming `RoutePayload` from
`twenty-sdk`. This PR adds a single row to the `RoutePayload` structure
table in `logic-functions.mdx` so the field is discoverable.
Addresses the review feedback on
