How to include a resource and its associations in the same request
When you fetch a resource or a collection, you can include its associations in the same request, using the include query parameter. This reduces the number of roundtrips, optimizing the performances.
The value of the include parameter must be a comma-separated list of relationship paths (see example). Pay attention to avoid whitespaces before or after each comma.
A relationship path is a dot-separated list of relationship names (see example).
