IntegrationHub ETL and DataSource from REST API

Hello together,

I am just trying out the possibilities with IntegrationHub ETL, because we want to fill the CMDB for our customer from different sources. And this relative new functionality seems nice.

As I understand, the source for an ETL Transform Map is a data source. My first steps for learning I have done with uploaded files (used the course in LeaningNow).

So now to my question: is the following scenario possible?

1. 3rd party sends data per scripted REST API into a defined table
2. this table should be the data source for an ETL Transform Map, which runs everey time, when new data is send per REST

But as data source I did not find a suitable option. So the scenario is not realizable? Or is there another way that we could use both scripted API in combination with IntegrationHub ETL?

Hope I could describe the situation understandable.

Thanks and kind regards,
anwie
