Subscription Upgrades is currently a Beta feature. Contact support via the in-app chat to have it enabled on your account.
This page covers everything specific to using Skio with Subscription Upgrades. For a full overview of how Subscription Upgrades work, see Subscription Upgrades.

​
Supported features

Skio supports all Subscription Upgrade types:
  • Change delivery or billing frequency
  • Replace with a different subscription product
  • Change frequency and replace product
  • Prepaid and postpaid frequencies

​
Generating your Skio API token

  1. In your Skio dashboard, go to API & Integrations → API.
  2. Enter a name for your new API key and click Generate API key.
  3. Copy the key immediately. It will only be shown once.
  4. Grant all necessary scopes: edit, delete, and create subscription.
For more details, see Skio’s API documentation.

​
Connecting Skio in the setup wizard

When you reach Step 1: Connect provider in the Subscription Upgrade wizard:
  1. Select Skio from the Subscription provider dropdown.
  2. Paste your API token into the API token field.
  3. Click Test API key. Aftersell validates the token, checking that it authenticates correctly, holds all required scopes, and belongs to your store.
  4. Once the test passes (green check), click Continue to move to Step 2.
The test result shows one of three states:
  • Green check (valid) — the token authenticated, all required scopes are present, and the token belongs to your store.
  • Red X (invalid) — the token was rejected or is missing required scopes. The message names the specific missing scopes. Fix the token in Skio and test again.
  • Warning (could not verify) — Aftersell could not reach Skio to complete the check. Test the key again. You cannot save until the check passes or clears.

​
Verifying an upgrade in Skio

After placing a test order and accepting the upgrade offer: Go to Subscriptions in your Skio dashboard and find the customer’s subscription. The line item, interval, and selling plan should reflect the change immediately. Skio updates in near real-time after acceptance.

​
Troubleshooting Skio-specific issues

The upgrade was accepted but the subscription was not modified The most common causes:
  • Your API token is expired or lacks the required permissions. The token must have edit, delete, and create subscription scopes. Go to Step 1: Connect provider, re-test your key, and check the error message for the specific missing scopes.
  • The eligible product in the funnel does not match what the customer actually subscribed to.
Aftersell automatically retries failed provider calls in a background workflow. If all retries fail, contact support with your store URL, the Shopify order ID, the customer’s email, the approximate time the upgrade was accepted, and the provider you are using. The selling plan dropdown is empty The “Use an existing selling plan” option pulls plans directly from Skio. If the dropdown is empty:
  • Confirm selling plans are configured in your Skio dashboard.
  • Make sure your API token has the appropriate read scopes.
  • Go back to Step 1: Connect provider, re-test your API key, and continue.
