OAuth error: invalid_scope when setting up Price Rules for Shopify app

Authentication & Access
1

Hi everyone,

I’m currently developing an app using Shopify’s API and facing an issue when attempting to generate discount codes via OAuth. Here’s the setup and error I’m encountering:

Background

  1. App Setup: I created the app directly through the Shopify Partner Dashboard, under Apps, and selected a development store for testing.
  2. App Installation: Installed the app on the dev store and successfully obtained the API Key and API Secret.
  3. OAuth Setup: I’m following Shopify’s OAuth process to request an access token with the write_discount_codes scope so I can create price rules and discount codes.

Issue

When I initiate the OAuth flow, I receive this error:

OAuth error invalid_scope: The access scope is invalid: write_discount_codes

Details

  • Store Plan: I’m using a development store, not a Shopify Plus or paid version.
  • Scope Configuration: I couldn’t find any options to configure the scopes directly in the Partner Dashboard for my app.
  • OAuth Scopes in Request: The request URL includes the write_discount_codes scope, which I believe is needed for managing discounts.

Questions

  1. Is the write_discount_codes scope available only on Shopify Plus or paid stores?
  2. How can I configure or verify the scopes for a Partner Dashboard-created app?
  3. Any recommendations on how to test discount code generation functionality in a development store setup?

Any guidance on resolving this would be greatly appreciated! Thank you!

Hi Ninja,

I think it should be write_discounts and not write_discount_codes. There doesn’t seem to be a write_discount_codes scope which is likely why you’re seeing this error.
