[API] standardize API response #124
Description
Describe the request
We want to standardize the API response output so that the API always returns a predictable structure, regardless of whether data is present or not.
e.g, for a void array, we want "array": [].
All the current implementations that produce "array": null or where the field is omitted should be checked
We should also check if an API guidelines document already exists for Arduino. If not, we should consider creating one.
Describe the current behavior
Our API responses lack consistency regarding how empty fields—specifically arrays and lists—are handled. In several endpoints, if a field has no value, the key is either completely omitted from the JSON payload or returned as null.
