This is more of a discussion topic than a question… 

I’m considering a customization that uses the REST API internally to access data stored in Acumatica.  I know that this isn’t the recommended API. I should be using the Platform API, but there is a good chance that what is being developped will eventualy move outside of Acumatica as a standalone application that talks to Acumatica.

What are your thoughts on this?

Using REST API internally in Acumatica ERP is technically possible, but not recommended due to performance overhead, separate transactions, and added complexity.

 

A better approach is to use the Platform API (graphs/DACs) and build a service layer abstraction. This way, if the solution is later moved outside Acumatica, you can replace the implementation with REST without changing your core logic.

Hi ​@PSchirf61,

Although there are few default endpoints ships with the Acumatica OOB. You can still create your own from scratch and only the absolute entities you need along with your customization. You can later include this endpoint in your customization project which can easily be deployed.
