ETL(extract-transform-load) tool/framework working with REST/JSON?

Question

JavaScript

Task: There are 2 CRMs, both provide a REST API, allow you to get and put JSON objects. you need to make friends with them, i.e. do data integration.
Here, either write your own thing and figure out how to describe the transformations, or use some kind of framework \ ETL tool that can help with this matter.
Maybe someone faced a similar problem and already knows how to solve it with little bloodshed?

Answer 1

Try looking at apache camel or similar from spring.
