# `Mailglass.Webhook.Providers.Resend`
[🔗](https://github.com/szTheory/mailglass/blob/v1.2.0/lib/mailglass/webhook/providers/resend.ex#L1)

Resend webhook verifier + normalizer.

Verifier: Svix-style HMAC-SHA256 over `svix-id.svix-timestamp.raw_body`.
Resend signs one or more `v1,<base64>` values in the `svix-signature`
header, allowing zero-downtime secret rotation. This verifier decodes
the configured `whsec_...` secret, enforces a replay window, and
compares signatures with `Plug.Crypto.secure_compare/2`.

Normalizer: decodes the JSON object body and maps Resend's `type`
strings into the Anymail taxonomy verbatim where possible. Unmapped
event types fall through to `:unknown` with `Logger.warning`.
