I’m not sure I know exactly what step you need help with. But there are some existing resources you can use to copy code and read about Resend configuration. Please give these a try and let us know how it goes!
- React Email with Resend template and repo (I deployed a test from this to make sure it works, just make sure you’ve added the RESEND_API_KEY environment variable)
- Send emails with Resend Node.js SDK
Hope that helps!
