Webhooks for open tracking are launched
As promised with the release of open tracking, we released the related open tracking webhooks. With webhooks enabled, Postmark will push the open tracking data to a URL you specify each time an open occurs. This notification will contain all of the great information you can see in the Postmark UI, Opens API and Outbound Stats API.
Webhooks are unique to each server in your account. You can add a webhook on the Server Settings page under the “Opens webhook” section.
By default, all of your email opens will get posted to your webhook. Postmark differentiates between the first and subsequent opens. Every JSON posted to your webhook will contain the property FirstOpen, showing if this was the first time the recipient opened the email. If you don’t care about subsequent opens, you can set a switch “Post only on first open“ on the Server Settings page.
Managing webhooks with the API #
All of the webhooks functionality can be managed with the API. On a per-server basis, you can call the /server endpoint using the X-Postmark-Server-Token. If you’re managing more than one server with an Account Token, you can use refer to the Account API.
