Plugins cannot verify signed webhook requests while the loader hides HTTP headers and parses the request body as JSON. Add opt-in
rawBody: trueroutes that receive original bytes and headers, enabling endpoint-secret verification in the private membership payment plugin.The buffer parser is encapsulated per route and retains Fastify's body-size limit. Existing routes retain JSON parsing, schema validation, authentication, and error mapping. SDK 1.0.10 exposes the optional transport fields; installations also need this server change, since upgrading the SDK alone does not update an existing server image.
Validation: server TypeScript build; all 14 plugin-route integration tests, including exact UTF-8/whitespace bytes, headers, malformed JSON, body limits and ordinary-route isolation; SDK suite and added opt-in contract test passed. The private payment plugin additionally passes 34 tests including real Stripe signatures, changed payloads, wrong/missing secrets, stale timestamps, duplicate delivery, and checkout refusal without a webhook secret.
