OpenAPI or Swagger Specs for Shopify

Are there Swagger or Open API specs available for Shopify integrations? The last I see is a thread from 2019 which mentioned that swagger specs are unavailable but am not sure if there is any update after that. Please suggest.

I am also looking for this.

None of the libraries help me as not my language of development.

Our customers currently do 20-30 million A year in eBay sales and we used an eBay package for Delphi that makes this stupid simple.

Would like to get Shopify added but looks like gotta use An exist library package or hand write everything yourself.. which means maintaining forever… which means… nope.
