Though PowerServer Compiler automatically converts all your data access related logic to the server side and packages it into REST APIs, it is not recommended to consume those restful APIs from another application since the transmitted data is formatted in a way for optimal commutation between the PowerServer client (cloud app) and the PowerServer server side. It is not suitable for external use.
PowerServer 2021 or above
Your PowerBuilder Cloud Pro package includes tools that designed for this scenario. The tools are included without extra charge and it is also high-automated and very flexible to expand.
