CATEGORY - alert category (Infrastructure, Consumers, Kafka Connect, Topics, Producers).
INSTANCE - (broker url / topic name etc.).
SUMMARY - alert summary - same content in the Alert Events tab.
TIMESTAMP
ID - alert global id (i.e. 1000 for BrokerStatus alert).
CREDS - CREDS[0] etc. - variables specified in connections Credentials as a list of values separated by a comma.

Webhook Email

To configure real-time email alerts you can leverage Webhooks, for example with the following service:

Twilio and SendGrid
Zapier

SendGrid Example

Create a webhook connection, for SendGrid with api.sendgrid.com as the host and enable HTTPS
Configure a channel to use the connect you just created
Set the method to Post
Set the request path to the webhook URL from your Zapier account
Set the Headers to

HTTP Headers
Authorization: Bearer [your-Sendgrid-API-Key]
Content-Type: application/json

HTTP Headers

Authorization: Bearer [your-Sendgrid-API-Key]

Content-Type: application/json

Set the payload to be

{
  "personalizations":[{
    "to":[{
      "email":"devops@mycompany.com",
      "name":"DevOps & SRE team | MyCompany"
    }],
    "subject":"PRODUCTION | Streaming Data Platform Alert"
  }],
  "content":[{
    "type":"text/html",
    "value":"<html><body><p>Priority Level:{{LEVEL}}</br></br>Category: {{CATEGORY}}</br><br>Description: {{SUMMARY}}</br><small>Alert ID: {{ID}}</small></p></body></html>"
  }],
  "from":{
    "email":"sender-email-address",
    "name":"sender name ie. PRODUCTION | Streaming Data"
  },
  "reply_to":{
    "email":"reply-to-email-address",
    "name":"reply to name"
  }
}

Change the above payload according to your requirements, and remember that the [sender-email-address] needs to be the same email address you registered during the Sender Authentication Sendgrid setup process.

Zapier Example

Create a webhook connection, for SendGrid with hooks.zapier.com as the host and enable HTTPS
Configure a channel to use the connect you just created
Set the method to Post
Set the request path tp /v3/mail/send
Set the request path to the webhook URL from your Zapier account
Set the Headers to:

X-Api-Token: {{CREDS[0]}

Set the payload to be

<html>
