Defined in:
app/controllers/fopost/rails/webhooks_controller.rb

Overview

Receives FoPost webhooks and republishes them as ActiveSupport::Notifications events, so subscribing costs no route, controller, or queue of your own.

ActiveSupport::Notifications.subscribe('fopost.post.published') do |*, payload|
Rails.logger.info(payload[:data])
end

Two events fire per delivery: fopost.<event> (fopost.post.published, fopost.delivery.failed, …) and fopost.webhook for a catch-all.
