http Issue sending two json-objects

Hi all

The endpoint I call (method: PATCH) expects json-objects with a line break.

{"code": "test2", "parent": null}
{"code": "test_adriano", "parent":null, "labels":{"en_US":"test"}}

How can I achieve this? If I format the body as text, the endpoint doesn't accept it. It expects the content-type:"application/vnd.akeneo.collection+json".

However ninox seams not to accept/execute the http-call contains a body with two objects in it.

Thx for help
