Postmark binding spec

Detailed documentation on the Postmark binding component

Component format

To setup Postmark binding create a component of type bindings.postmark. See this guide on how to create and apply a binding configuration.

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: postmark
spec:
  type: bindings.postmark
  metadata:
  - name: accountToken
    value: "YOUR_ACCOUNT_TOKEN" # required, this is your Postmark account token
  - name: serverToken
    value: "YOUR_SERVER_TOKEN" # required, this is your Postmark server token
  - name: emailFrom
    value: "testapp@dapr.io" # optional
  - name: emailTo
    value: "dave@dapr.io" # optional
  - name: subject
    value: "Hello!" # optional
  - name: direction 
    value: "output" # optional

Spec metadata fields

Field Required Binding support Details Example
accountToken Y Output The Postmark account token, this should be considered a secret value "account token"
serverToken Y Output The Postmark server token, this should be considered a secret value "server token"
emailFrom N Output If set this specifies the ‘from’ email address of the email message "me@exmaple.com"
emailTo N Output If set this specifies the ’to’ email address of the email message "me@example.com"
emailCc N Output If set this specifies the ‘cc’ email address of the email message "me@example.com"
emailBcc N Output If set this specifies the ‘bcc’ email address of the email message "me@example.com"
subject N Output If set this specifies the subject of the email message "me@example.com"
direction N Output The direction of the binding "output"

You can specify any of the optional metadata properties on the output binding request too (e.g. emailFrom, emailTo, subject, etc.)

Combined, the optional metadata properties in the component configuration and the request payload should at least contain the emailFrom, emailTo and subject fields, as these are required to send an email with success.

Binding support

This component supports output binding with the following operations:

  • create

Example request payload

{
  "operation": "create",
  "metadata": {
    "emailTo": "changeme@example.net",
    "subject": "An email from Dapr Postmark binding"
  },
  "data": "<h1>Testing Dapr Bindings</h1>This is a test.<br>Bye!"
}
