Seal Subscription (Add-On)

Let vendors sell products with recurring billing plans using the Seal Subscriptions app

⚡ Quick Summary

Add the add-on in Settings → Subscription and billing. Copy the API token from the Seal Subscriptions app in Shopify and paste it in Settings → Integrations → Seal subscription. Create rules in the Seal app, then pick one in the Subscription Rule dropdown on a product.

Overview

Seal Subscription is an add-on ($30/month) that connects Shipturtle to the Seal Subscriptions Shopify app. Vendors can offer monthly, annual, or lifetime plans on their products. Once a plan is assigned, the subscription widget appears on your storefront automatically.

Setup in five steps:

  • Enable the add-on.
  • Get the API token from the Seal app.
  • Connect Seal in Shipturtle.
  • Create subscription rules in the Seal app.
  • Assign a rule to a product.

1. Enable the add-on

  1. Settings → Subscription and billing → Additional Add-ons → Product & Listings
  2. On the Seal Subscription card ($30/month), select Add. Active add-ons show Added.
  3. Check the You have selected panel → Proceed to payment

  2. Settings → General Settings → API
  3. Tick Enable API
  4. Copy the token. It starts with seal_token_.

3. Connect Seal in Shipturtle

4. Create subscription rules in Seal

Rules set the billing plans customers can choose. Create them in the Seal app, not in Shipturtle.

  1. Shopify admin → Apps → Seal Subscriptions → Subscription rules
  2. Create rule and set the plan (Monthly, Annual, or Lifetime).
  3. Save. Repeat for each plan.
  • Examples: Monthly + Annual, Annual + Lifetime, Lifetime only (one-time purchase), or all options.
  • Create as many rules as you need.
  • Deleting a rule does not cancel active subscriptions. They keep working.

FAQs & Troubleshooting

  • The Subscription Rule dropdown is empty.
    The access token is missing or invalid, or Enable API is unticked in Seal. Check Settings → Integrations → Seal subscription in Shipturtle, then Settings → General Settings → API in the Seal app.
  • Customers can't see the subscription widget.
    Confirm the product has a rule and is published. In the Seal app's Subscription rules page, check for the banner "The widgets are enabled in your shop." If widgets are disabled, select Enable.
  • Can vendors assign rules themselves?
    Yes, once the integration is connected and you have created rules in the Seal app. They pick a rule from the Subscription Rule dropdown when adding or editing their products.
  • Does removing a rule cancel active subscriptions?
    No. Existing subscriptions keep working even after the rule is deleted.
  • Where are recurring payments managed?
    In the Seal Subscriptions app in your Shopify admin. Shipturtle shows the plans on the product form but does not process billing.
