You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: base.rb
    path of file: ./repos/chaskiq/app/services/data_enrichment_service
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module DataEnrichmentService
  class Base
    def initialize(provider:, token:)
      # conn.authoriz
    
    def initialize(provider:, token:)
      # conn.authorization :Bearer, 'mF_9.B5f-4.1JqM'
      #   conn.headers['Authorization']
      #   # => "Bearer mF_9.B5f-4.1JqM"
      #
      #   conn.authorization :Token, token: 'abcdef', foo: 'bar'
      #   conn.headers['Authorization']
      #   # => "Token token=\"abcdef\",
      #               foo=\"bar\""

      @token = token

      @conn = Faraday.new request: {
        params_encoder: Faraday::FlatParamsEncoder
      }

      klass = "MessageApis::#{provider.to_s.camelize}"::Api.constantize
      klass.new(token: token)
    end
