Checkout behavior

I’m building a non-embedded app and use the checkout URL generation to sell subscribable items. I have setup my app to use the subscriptions API, and the URL looks similar to this https://<storeName>.myshopify.com/cart/clear?return_to=/cart/add?&items[][id]=${itemId}&items[][quantity]=${itemQuantity}&items[][selling_plan]=${selling_plan_id}&items[][ref]=${referrerData}&items[][note]=${orderNote}&return_to=/checkout But instead of taking me to checkout I’m redirected back to my main storefront https://<storeName>.myshopify.com/ with no errors or messages.

Hey @otothes ,

Your issue might be related to improper configuration or usage of the URL parameters or missing permissions required for the Subscriptions API. Here’s a step-by-step guide to troubleshooting and resolving the issue:

  1. Check the URL Structure:
  • Ensure the return_to parameter is correctly formatted.

  • It should redirect to a valid Shopify path (e.g., /checkout or another valid URL).

  • Avoid chaining multiple return_to parameters as this can cause issues.

Double-check the parameters:

  • items[id] : Ensure it matches the correct variant ID.

  • items[quantity] : Must be a valid number.

  • items[selling_plan] : Verify the selling_plan_id is correct and active.

-Example of a simplified URL:

https://

2. Verify App Permissions:

Make sure your app has the correct access scopes in the Shopify Partner Dashboard:

read_products

write_checkouts

read_checkouts

write_orders

read_orders

subscriptions

If any of these are missing, update your app's OAuth scopes and reauthenticate your app.

3. Selling Plans Validation:

-Check if the selling_plan_id you’re using is associated with the product and its variants.

-Ensure the subscription is correctly set up for the items in the Shopify Admin under **Products > Subscriptions**.

4. Test the Redirect Behavior:

Try using a simplified version of the URL without additional parameters like ref or note to isolate the issue:

```markup
https://

5. Enable Checkout API Access

Ensure your app is configured to use the Shopify Checkout API. Without this, the checkout redirect may not work as intended.

6. Inspect Logs and Console:

- Look for errors in the browser’s console or network tab when the redirect happens.

- Check your app server logs to ensure the request is processed correctly.

7. Test in Development Mode:

- Use a development store to test the functionality in a controlled environment.

- Make sure the development store supports subscriptions (not all plans or store types support this).

8. **Consult Shopify Documentation:**

**Refer to the Shopify Subscriptions API documentation to ensure you’re implementing the API correctly.**

**If the issue persists, provide additional details or errors encountered during testing for further assistance.**

**Please send me a message via email so we can discuss this in more detail. I’d be happy to assist you further with my 5 years of experience. Looking forward to helping you! :blush:**
