Set Up your Appstle Integration

Who gets this? Shops on all Postscript's Professional and Enterprise plans have access to this feature. Learn more about Postscript Plans.

We integrate with Appstle so you can empower your SMS subscribers to manage their subscriptions right from their text thread! In this article, we discuss how to configure the integration. Then, we'll guide you through how to create an Appstle automation and define Appstle automation triggers.

Create a Postscript 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 or write it down—you'll need to enter it in Appstle later.

Configure Postscript in Appstle

  1. From your Shopify admin, select the Appstle app on the left-side navigation panel.
  2. Navigate to Settings, then select General Settings.
  3. Select App Integrations and find the Postscript integration, then enter the API key you generated inside Postscript from earlier in this article.
  4. Select Save.

Create an Appstle Automation

  1. From your Postscript Dashboard, select Messages; then select Automations.
  2. Select Create Automation in the upper-right corner. Select Create Automation Flow.
  3. Select Create a new automation, then Create flow.
  4. Name your automation. Be sure to use a name that will allow you to easily identify and track this automation in the future.
  5. Select the dropdown menu under Add a subscriber when, then choose your Appstle trigger.
  6. Continue customizing your automation flow by dragging and dropping actions into your flow, customizing your message, and adding merge tags.
  7. When you're ready to send your flow, select Schedule or Activate in the top-right corner of the page. You have two options when sending a flow:
    • Activate immediately: This option will immediately begin the flow allowing subscribers to enter the automation based on the selected properties.
    • Activate at a scheduled time and date: Choose when you'd like the flow to begin allowing subscribers to enter.
