Changing the endpoint to use API Key

I am confused as to how to finish the function at the end. It says "Do the usual stuff!" and it is just not intuitive for me yet.

class YelpAPIClient {
    var apiKey: String {
        // ideally fetched from keychain or somewhere secure
        return "sample_key"
    }

    let session: URLSession

    init(session: URLSession) {
        self.session = session
    }

    func searchBusinesses() {
        let endpoint = Yelp.business(id: "abcdefg")
        // Inside the client, when we retrieve the request object from the endpoint, we're
        // passing in the apiKey
        let request = endpoint.request(withApiKey: apiKey)

        // Do the usual stuff!
    }
}
