Requesting all deals in a pipeline does not request person fields

Hey,
So i’m new to the API but from what i can see if i specify a pipeline the data i get back seems to only be the deal data not also the person.
https://api.pipedrive.com/v1/pipelines/8/deals?api_token="" - This gets me all the deals i need but not all the data
https://api.pipedrive.com/v1/deals/17624?api_token="" - This gets me all the fields i need but only does for specific deal
Is there anyway to specify the pipeline AND also get all person fields?

Thanks,
