Anyone knows what might be the issue in these cases
Topic summary
Approved public Shopify app cannot retrieve order details via API after installation, while a custom app with the same permission scopes can. The author attached screenshots comparing the custom app vs the public app results.
Key suggestion: A participant notes that the read_orders scope only allows access to orders from the past 60 days. To access historical orders beyond that window, the app should request the read_all_orders scope.
Open questions: It’s unclear whether the affected store’s orders fall outside the 60‑day window, or if there are other permission/auth differences despite “same scopes.” No confirmation from the original poster that the suggestion resolved the issue.
Status: Unresolved/ongoing. Next action is to verify the order date range being requested and, if needed, obtain/read_all_orders to fetch historical orders.
