Test Automation for full stack integration tests

I wanted to understand what frameworks are available for full stack integration tests for testing backend API's. In particular we have several springboot microservices, in a multi-layer architecture that we would like to test end-to-end.

1. What frameworks are available, for end-to-end full stack integration tests?

2. How do these frameworks enable orchestrating/running the applications?

I've checked out selenium but that seems to be more browser facing, and I only care about testing API's.
