Hi,
To get the list of collections that reference a specified entity, please refer to the following API request (see Producer-Service-Entity section of the swagger documentation):
GET /publication/{publicationID}/{entityType}/{entityName}/{referencingEntityType}
The above request has been added to the DPS2015 Content Producer API examples, you can now use the function getReferencing(). Please see /article/get_referencing_entity.php for the full example.
You can download the latest DPS2015 Content Producer API examples and swagger documentation from here, all the resources are in a single zip file.
