CheckoutChamp is a CRM and checkout platform for high-volume and subscription commerce. Postscript integrates with CheckoutChamp so you can turn checkout and subscription activity into timely SMS. With our CheckoutChamp integration, you can:
Create Postscript subscribers tied to your keywords directly from CheckoutChamp checkouts.
Trigger pre-configured Postscript automations to re-engage customers based on order and subscription events.
This article walks you through the prerequisites, retrieving your Postscript API key, activating the plugin in CheckoutChamp, and mapping your automations.
Before You Begin
Before setting up the integration, confirm the following:
You have an active Shopify store connected to CheckoutChamp.
Customers explicitly opt in to SMS marketing using a checkbox at checkout.
Subscribers are added once they reply Y to the initial SMS. A reply of NO or N prevents the subscriber from being added.
Compliance Requirements
When collecting subscribers, the TCPA requires you to include necessary compliance language that informs visitors they are opting into SMS messaging from your store.
Here's the TCPA-approved compliance language:
*By providing your number and clicking the button, you agree to receive recurring auto-dialed marketing SMS (including cart reminders; AI content; artificial or prerecorded voices) and our TERMS OF SERVICE (including arbitration). Consent is not required to purchase. Msg & data rates may apply. Msg frequency varies. Reply HELP for help; STOP to opt-out. View PRIVACY POLICY.
IMPORTANT: To help support compliant subscriber collection, your Terms of Service and Privacy Policy should be directly linked within the compliance language shown above.
Postscript recommends using hosted Dynamic Terms of Service and Messaging Privacy Policy links wherever SMS consent is collected, including popups, embedded forms, landing pages, and checkout opt-in experiences.
If hyperlinks cannot be used, include the full URLs for your messaging Terms of Service and Messaging Privacy Policy so visitors can access them directly.
For example: View our Terms of Service (https://myshop.com/terms-of-service/) and Privacy Policy (https://myshop.com/privacy-policy/).
Step 1: Retrieve Your Postscript API Key
Select your Shop Name in the side menu of your Postscript dashboard, then select API.
Select Create Security Key Pair on the right side of the page, then confirm your action by selecting Yes.
Add a label to your API key so you can track where this API key is being used.
Select Show in the Private Key column to reveal your API key. Copy this key or write it down—you'll enter it in CheckoutChamp in the next step.
Step 2: Activate the Postscript Plugin in CheckoutChamp
In CheckoutChamp, navigate to Admin > Plugins > Email Service Providers.
Locate Postscript and select +Activate.
Enter your Postscript private API key from Step 1.
Enable the useV2Api option.
Select Connect.
Activating the plugin automatically creates the corresponding automation triggers in your Postscript account.
Available Automation Triggers
The integration supports the following triggers:
Charge_Failed
Order_Cancelled
Order_Created
Order_Declined
Subscription_Cancelled
Subscription_Started
Subscription_Upcoming_Charge
Step 3: Configure Message Fields
You can personalize automated messages using the following dynamic tags:
client_orderid
first_name
last_name
email_address
phone_number
shop_name
shop_link
sales_url (specific to checkout)
If you need additional custom tags, contact your CheckoutChamp account manager.
Step 4: Set Campaign Routes
Pre-configure the automations you want to use in your Postscript account.
Back in CheckoutChamp, return to Admin > Plugins > Email Service Providers.
Select Edit on the activated Postscript tile.
Open Advanced Setup and use the green + button to add new routes.
Step 5: Create an Opt-in Checkbox
Add a marketing opt-in checkbox to your checkout pages using CheckoutChamp's page builder tools. This checkbox captures the explicit consent required before a subscriber can be added.
Step 6: Final Configuration
Confirm with your CheckoutChamp Account Manager that your company is included in the Postscript task schedule.
Once enabled, subscribers are added after an order is created in CheckoutChamp.
