Hey, @obsidian swallow!
Please remember to /close this post once your question has been answered!

Example of other returns in the same method:

{ "destination": { "id": "100", "balance": 10 } }

By the way, I can't create different endpoints because the business rule don't does not allow. The same endpoint with the same HTTP method should return different objects depending of the input

......... A Map can contain as many objects as you want

Note that with the example given, I don't quite see why you can't return an OriginAndDestination rather than a Map

[obsidian swallow]

Yes, but the return is Map<String, Object>, and the case showed is Map<Object, Object>

What do you mean?

[obsidian swallow]

Required type: ResponseEntity <Map<String, Object>>
Provided: ResponseEntity <Map<Object, Object>>

[warped totem]

Well give a Map<String, Object> rather than something else

[obsidian swallow]

But the return is two objects:
{
"origin":
{
"id":"100",
"balance": 0
},
"destination":
{
"id": "300",
"balance": 15
}
}

And there is others return in the same method where is returned a Map<String, Object>

Dude, key, and value

Map<String, Object> means you can put as many objects as you want, each associated with its own String

Clearer?

Ok, I have these two Maps:

    Map<String, Object> origin = new HashMap<>();
    Map<String, Object> destination = new HashMap<>();

For this object which I'm responding. How can I merge they?

Because I think this is the object:

{
"origin":
{
"id":"100",
"balance": 0
},
"destination":
{
"id": "300",
"balance": 15
}
}

But, what is the key?

[warped totem]

response.put("origin", origin);

response.put("destination", destination);
