It covers configuring the Resend developer portal, enabling click/open tracking, building a simple Next.js email template and send API, and verifying incoming webhook payloads before triggering a Slack message via an incoming webhook app. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I verify a Resend webhook signature in a Next.js API route? Use the svix library's Webhook class, passing the webhook secret from Resend, then call webhook.verify() with the raw request payload and headers. The payload must be read as a raw buffer (with bodyParser disabled in the Next.js API config) rather than parsed JSON, since signature verification requires the exact raw bytes. _Developers wiring up webhook security often track integration patterns like this on daily.dev._ ### How do I get notified when someone opens or clicks a link in an email sent through Resend? Set up a webhook in the Resend developer portal and select the email.opened or email.clicked event types, then add an endpoint URL to receive them. Click and open tracking must also be enabled per sending domain in the Domains tab before these events will fire. _Anyone automating email engagement alerts can find setup guides like this via daily.dev._ ## Similar posts on daily.dev - [Resend joins the Vercel Marketplace](https://daily.dev/posts/resend-joins-the-vercel-marketplace-t3hgvfr5j) · Vercel · 4 upvotes · 2 comments - [Integrating Resend with Auth0 for Email Delivery](https://daily.dev/posts/integrating-resend-with-auth0-for-email-delivery-tiasi9k4c) · Auth0 · 0 upvotes · 0 comments - [Introducing Huntress Webhooks.
