Response
This section shows the JSON response returned by the API.
Each API client encapsulates this response inside objects specific to the programming language,
so that the actual response might be different.
You can view the response by using the getLogs
method.
Don’t rely on the order of attributes in the response, as JSON doesn’t guarantee the ordering of keys in objects.
