In many endpoints you'll find a fields query parameter that can be passed to the endpoint. You can use the fields query parameter to specify which fields in the entity should be returned in the response.Please note that if you pass a fields query parameter, only the fields you pass in the value along with the id of the entity will be returned in the response.Also, the fields query parameter does not affect the expanded relations. You'll have to use the expand parameter instead.
For example, when you retrieve a list of products, you can retrieve only the titles of the products by passing title as a value to the fields query parameter:
