Arrow alignment to use case

Question

I'm new to plantuml and trying to get my head around it. Can anyone show me the right syntax to align arrows to the center of a box? I've included a picture of what it looks like as default. The below just look messy, is there a way for the arrows to be connected to the center and not the bottom.

Hello W.,

From your diagram:

If you never use link with "API 1" or "API 2" outside Integrations, a workaround is to use long description ('[' and ']'), sub-diagram ('{{' and '}}'), and an hidden arrow as:

Rectangle INT #white [
<b>Integrations
{{
    usecase "API 1" as A1
    usecase "API 2" as A2
    A1 -[hidden]-> A2
}}
]

Then, we observe the expected result:

That's only a workaround...

If that can help,
Regards,
Th.
