You can create and send LINE messages to your subscribers, using text, image, or video content. LINE deliveries can be created as standalone deliveries or added to a workflow.

This page walks through creating a standalone LINE delivery, but the same steps apply when configuring a LINE channel activity in a workflow.

IMPORTANT
Message preview is not currently supported for LINE deliveries. Review your content carefully in the editor before sending, since you cannot preview the rendered message beforehand.

  1. Browse to the Deliveries menu, and click Create delivery.

  2. Choose LINE and select a delivery template, such as the default LINE V2 delivery template. Learn more about templates.
