communication between micro-services after completed some thing

Question

Let's say we have two microservices: MeetingProposal and Meeting.

Process of creating a meeting:

• To create a meeting, users should propose their request, after their request, we create a proposal and show it to the admin.
• If admin accepts the proposal then we should change the status of proposal to accepted and also create a meeting in the meeting microservice.

Question:
How we should connect these two processes to each other (after proposal accepted => create meeting automatically)?

Answer 1

It's called business processes management, long running flows, sagas, or similar(see this)

We should use some orchestration engines like Cadence or Netflix Conductor or any other orchestration engine.
