# Profiles This directory contains specific customisations for each endpoint, called *profiles*. They **parse data from the API differently, add additional information, or enable non-default methods** (such as [`trip`](../docs/trip.md)) if they are supported. Each profile has it's own directory. It will be passed into `hafas-client` and is expected to be in a certain structure: ```js const createClient = require('hafas-client') const someProfile = require('hafas-client/p/some-profile') // create a client with the profile const client = createClient(dbProfile) // use it to query data… ```
