Starting workflow instance from CAP service

[js2]

I'm wondering if its possible (and if any examples exist) for starting a CF workflow instance from a CAP application?

I can see examples (and the open sap cap course - week 4) cover calling external services but these are always OData services with an edmx file that can be used with the `cds import` command.

(According to `cds help import`: "Currently only OData EDMX input is supported".)

The workflow APIs (https://api.sap.com/api/SAP_CP_Workflow_CF/overview?name=SAP_CP_Workflow_CF&type=JSON∾tion=download&artifactType=REST) are REST API's only (not OData).

Alternative options would be to code the rest call directly in the UI5 app (though architecturally it seems better to do this from the cap service) or to fire an enterprise messaging event (which my cap service is doing anyway) and using CPI to capture that event and call the workflow api.

Thankyou david.kunz2 and pdominique-bio. Will investigate this method. The fact that cds import states it only works with edmx files had me thinking I could only work with OData.

Hi Jason,

Yes you can implement custom handlers to achieve this. There's also a library to help with that: https://github.com/sapmentors/cds-scp-api
