  # Resend Integration

## Overview

`@botpresshub/resend` is an integration that allows a Botpress chatbot to send emails via the Resend API.

## Configuration

### Authenticating your domain (https://resend.com/domains)

1. Login to the Resend dashboard (https://resend.com/)
2. In the navigation bar on the left, click on "Domains"
3. Near the top-right, click "Add Domain"
4. In the "Name" field, enter your domain (e.g. "Botpress.com")
5. (Optional) Select the server region closest to your user base
6. (Optional) Customize the return path (Only recommended if you know what this does)
7. Click "Add Domain" (Below "Advanced options")
8. Add the DNS records in the portal of your domain provider (e.g. SquareSpace, GoDaddy, etc.)
   1. While the DMARC record is optional, it's recommended to protect against spoofing/unauthorized use of the domain
9. Click "I've added the records" and wait for each status to be marked as "Verified"
10. Now you're ready to send emails with your domain. Happy Emailing!

### Acquiring an API key (https://resend.com/api-keys)

1. Login to the Resend dashboard (https://resend.com/)
2. In the navigation bar on the left, click on "API Keys"
3. Near the top-right, click "Create API Key"
4. Give the key a name & grant the key "Sending Access"
   1. Optionally, choose which domains you want the key to send emails through
5. Click "Add" to generate the API Key
6. Copy the resulting API key into a secure location as it will only be shown once

### Setting up Webhooks (https://resend.com/webhooks)

1. Login to the Resend dashboard (https://resend.com/)
2. In the navigation bar on the left, click on "Webhooks"
3. Near the top-right, click "Add Webhook"
4. Copy the webhook URL from the Botpress integration config & paste it into Resend's "Endpoint URL" input field
5. Select which webhook events you want to listen for
6. Click "Add" (Below the "Select events to listen" section)
7. (Optional, but recommended) Copy the "Signing Secret" from Resend and paste it into the "Webhook Signing Secret" of the Botpress integration config
8. Now your bot is ready to listen for events from Resend

## Side Notes

The current implementation is limited to only sending [markdown](https://spec.commonmark.org/0.31.2/) rich-text emails, though this will be expanded upon in the future.
