Q) How to create API services and use them in SAP Digital Manufacturing

[Wonpyo]

Question

I want to practice creating APIs in the API Services tab of the Manage Service Registry App. However, it is difficult to develop a service that goes into URL/Path.

I'd like to have basic and sequential examples and guides. If possible, I would like to use the Visual Studio Code as IDE for service development.

Furthermore, where can we use custom API if it is possible to create them? Does creating API mean custom APIs are uploaded to the endpoint and possible to use like provided-APIs during plugin development?

FYI, Background

I''m a beginner of SAP Digital Manufacturing and IT. I've developed few view-plugs with SAPUI5 and Visual Studio Code(IDE) and expanded them to DM POD. The plugins I made can get or post with provided APIs. I uploaded my custom POD to BTP sub-account and registered that route in the UI Extension tab of the Manage Service Registry. I've only developed plug-ins in the view format.

Kind regards,

SAP Digital Manufacturing

Hi Wonpyo,

Please take a look at these blogs for an example of how to set up an external API:

https://community.sap.com/t5/product-lifecycle-management-blogs-by-sap/integrating-microsoft-teams-w...

https://community.sap.com/t5/product-lifecycle-management-blogs-by-members/external-api-web-service-...

In the first blog I explain how to create a webhook in microsoft teams (API) and then configure this in DM.

If you want to create you own API then what I normally do is write a Node JS application using VS Code and the Express framework and then push this into the SAP BTP Cloud Foundry service, it can then be registered in the service registry.

This tutorial show how to create and deploy a node JS app into cloud foundry https://developers.sap.com/tutorials/btp-cf-buildpacks-node-create.html 

Let me know if you need more details.

Thanks
