Can shopify use an older version of an app?

Topic summary

A developer created a Shopify checkout app that writes custom attributes for order processing. Despite releasing multiple updates from the initial version, they continue to receive new orders with data formatted according to the old version.

The Issue:

  • New version format shows simplified attribute structure (shown in first image)
  • Old version format displays different attribute layout (shown in second image)
  • Newer app versions include additional fields that don’t exist in older versions

Core Question:
Can Shopify automatically use older versions of an app on its own? The developer is concerned because this version inconsistency creates significant problems for their internal processing system, as they’re unable to predict which data format incoming orders will use.

Hi,

I was wondering if shopify could use older versions of an app by itself?

I made a checkout app that writes custom attributes for internal processing purposes.

I made a lot of updates from it’s first version but still find new orders with old format data:

old:

it is a very big problem as I added new fields that doesn’t exist in older versions.
