Set Up Your Loop Integration

Postscript integrates with Loop, allowing you to share information between the two solutions. With Loop, you can offer your customers a personalized and automated subscription experience.

In this article, we discuss how to configure the integration and define Loop-specific automation triggers.

Create a Postscript API Key

Before configuring Postscript in Loop, you'll need to generate a private API key that you'll enter into Loop later. In this section, we'll walk you through how to generate your private API key.


  1. Select your Shop Name in the side menu of your Postscript dashboard, then select API.
  2. Select Create Security Key Pair on the right side of the page, then confirm your action by selecting Yes.
  3. Add a label to your API key so you can track where this API key is being used.
  4. Select Show in the Private Key column to reveal your API key. Copy this key-- you'll need to enter it into Loop later.

Configure Postscript in Loop


  1. From the Loop dashboard, select Integrations on the left-side navigation panel.
  2. Find the Postscript integration, then enter the private API key you generated inside Postscript from earlier in this article.
  3. Select Connect.
