The Postmark component is used as a developer friendly email delivery service

Connections

Postmark Token Authentication

Authenticate requests to Postmark using values obtained from the developer console.

Access Tokens are necessary for interacting with the Postmark API. Access tokens are unique to each server you create in Postmark.

To generate an Access Token, you should log in to Postmark and navigate to your server page. Within the server settings, you can find your access tokens.

Postmark provides two types of access tokens:

1. Server Token: This token is used to send emails and perform other server-related actions in Postmark.

2. Account Token: This token is used to perform account-level actions, such as creating and managing servers.

For your integration, you will need both the Server Token and the Account Token.

For more information about access tokens, refer to the Postmark Docs.
