Back in Stock

Send Back in Stock alerts to your subscribers with this quick and easy integration! (Be sure to install Back in Stock before setting this up!)

Integrating Back in Stock with Postscript

Obtain your Postscript API Key

    • Navigate to your Postscript account, click on your name in the top-right corner, and choose API.

  • Then click Create Security Key Pair.

  • Click the hyperlinked Show text.

  • Copy that Private API key to your clipboard to add to Back in Stock's admin later.

Create a Keyword in Postscript

Now you'll need to create a keyword and keyword reply within Postscript so that you have a way for your Back in Stock users to opt into your subscriber list. When you installed Postscript, you were given two default keywords that you can use if you want, or instructions here will show you how to create a custom keyword. Remember, custom keywords are not available on the free tier.

  1. First, click "Keywords" on the left.

  2. Next, click "Create Keyword", found at the top right of the screen.

  3. Name your keyword, decide if you will include a coupon in the reply, and save.

  4. If you want to edit the reply, click the purple "Reply" box or to create an automatic reply to this keyword, click "Add Action" and then create your reply. The Keyword Reply that you create is the text they'll immediately receive upon subscribing via Back in Stock.

  5. Follow the instructions below to include this keyword later for new subscribers to trigger.

Completing the Integration within Back in Stock

  1. Log in to the Back in Stock Alerts app dashboard.
  2. Go to the Integrations tab.
