Bad Request

Technical Q&A

Topic summary

A user is encountering a “Bad Request” error when attempting to access their Shopify store’s admin panel via a URL ending in admin.php. The storefront itself loads normally for customers.

Key clarification provided:

  • Shopify does not use admin.php URLs for admin access
  • All admin functions are accessed through admin.shopify.com instead

Troubleshooting suggestions:

  • Try accessing the admin panel via the correct URL: https://admin.shopify.com/
  • One responder asked about potentially outdated API versions and requested request parameters for further diagnosis

The issue appears to stem from using an incorrect/outdated admin URL format rather than a technical malfunction.

I can access my Shopify store online as a customer, however when I try the same URL but to access admin.php I get the error Bad Request.

Never had this before

Hi @GL9

Is the API version you are currently using outdated? Can you share your request parameters?

Shopify doesn’t use admin.php for URLs since all store admin access is handled through admin.shopify.com.

Could you try this again? https://admin.shopify.com/
