ApiPlatform\Serializer\Filter\GroupFilter

The group filter allows you to filter by serialization groups.

Syntax: ?groups[]=<group>.

You can add as many groups as you need.

Three arguments are available to configure the filter:

parameterName is the query parameter name (default: groups)
overrideDefaultGroups allows to override the default serialization groups (default: false)
whitelist groups whitelist to avoid uncontrolled data exposure (default: null to allow all groups)

Given that the collection endpoint is /books, you can filter books by serialization groups with the following query: /books?groups[]=read&groups[]=write.
