API Calls Yielding Inconsistent/Stale Data in Shopify Environment (Working Correctly Locally)

Shopify Discussion

Topic summary

A developer using Shopify Hydrogen is experiencing data inconsistency issues with API calls that work correctly in local development but fail in the Shopify environment (both production and preview).

Core Issue:

  • API responses in Shopify return stale or inconsistent data on identical requests
  • Same code with identical API keys/endpoints works properly locally
  • No underlying data source changes explain the discrepancies

Troubleshooting Already Completed:

  • Browser cache cleared
  • API credentials and endpoints verified
  • Console and Shopify logs checked for errors

Seeking Help With:

  • Shopify-specific caching mechanisms beyond browser caching
  • Platform-specific API request handling behaviors
  • Environment configuration differences that could cause data staleness

The discussion remains open with no responses yet. The developer is looking for guidance on Shopify environment quirks that might explain why API data integrity differs from local development.

Hi,

I am using shopify hydrogen.I’m encountering a persistent issue where API calls from my application/theme are behaving differently in the Shopify environment compared to my local development setup.

Problem Summary:

  • Local Development: All API calls function as expected, returning accurate and consistent data.
  • Shopify Environment (both): When the same code is deployed/previewed on Shopify, the API requests are returning unexpected and inconsistent responses. The data often appears stale, or different data is returned on subsequent identical requests, without any underlying changes to the data source that would explain this.

Specifics:

  • The core problem seems to be with the data integrity or freshness of API responses within the Shopify platform.

Troubleshooting Attempted

  • Cleared browser cache
  • Verified API keys and endpoints are identical to the local setup that works.
  • Checked for errors in browser console and Shopify logs

Request:

Could you please provide guidance on why these discrepancies might be occurring specifically within the Shopify environment? Are there known Shopify-specific caching mechanisms (beyond standard browser caching), API request handling quirks, or environment configurations that could lead to such inconsistent or stale data from external API calls?

Any insights or troubleshooting steps you can offer would be highly appreciated.

Thank you for your time and assistance.
