OAuth Token Missing V3 Catalog Write Scope - HTTP 404 on /catalog/v3/products

Hi Wix Team,

We’re developing a SaaS app that integrates with Wix stores to sync products via OAuth 2.0.

PROBLEM:
Our app cannot create products on V3 stores using the Catalog V3 API. We get HTTP 404 errors.

WHAT WE’VE DONE:
:white_check_mark: Added permission “Product write in v3 catalog” in Developer Center
:white_check_mark: Released app versions multiple times
:white_check_mark: Implemented full OAuth flow - tokens generate correctly
:white_check_mark: Tested with V1 API - works perfectly (HTTP 200)
:white_check_mark: Tested with V3 API - returns HTTP 404

ROOT CAUSE FOUND:
OAuth tokens are being issued but WITH NO SCOPES:

Token payload shows:
“scope”: []

It should be
“scope”: [“SCOPE.STORES.PRODUCT_WRITE”]

EVIDENCE:

  • Token is valid JWT (recognized by Wix, not 401 error)
  • V1 Products API works fine (proves integration is correct)
  • V3 Product API returns 404 (permission denied, not endpoint missing)
  • Issue is specifically: empty scope array in OAuth token

REQUEST:
Please activate SCOPE.STORES.PRODUCT_WRITE I have tried all option I went in permission added permission V3 catalog and saved but still lack of v3 catalog fo every new token am getting

  1. New OAuth tokens include the scope
  2. V3 catalog endpoint returns 200 instead of 404
  3. We can support customers with V3 stores

This is blocking production deployment for V3 store support. V1 stores work fine.

Thank you!
