What's the best way to do step through a sequence of events

I’m trying to create a custom event or API which steps through a sequence of API calls, but it must happen in order.

What’s the best way to do this?

Maybe you can explain a little bit more?
For now, I can only suggest to read this: Actions | Bubble Docs
But working with API is different and you depending of what you are doing, it could be a mix of differents solutions (like request > wait for webhook response > trigger another request…)

I think this answers the question:

Custom events run in sequence, not parallel. If Workflow 1 triggers a custom event that starts Workflow 2, Workflow 2 will complete before the remaining actions in Workflow 1 run.

So I need to build it as a series of custom events which trigger each other
