Summary
POST https://api.resend.com/webhooks(matching Postmark/Mailgun behavior) instead of telling users to do it manually. Checks for existing webhooks to avoid duplicates and outputs the signing secret for the user to save.svix-id,svix-timestamp,svix-signatureheaders) with 5-minute timestamp tolerance. Gracefully falls back to accepting all webhooks if no signing secret is configured.tagsto data mapping for richer event data extraction.getUuidFromPayloadwhen headers are missing from the payload.New config key
Users should add
services.resend.webhook_signing_secretto their config after running the webhook registration command. The secret is returned by Resend's API on webhook creation.Test plan
