Usage

require "yoti"

Yoti.configure do |config|
  config.client_sdk_id = ENV["YOTI_CLIENT_SDK_ID"]
  config.key_file_path = ENV['YOTI_KEY_FILE_PATH']
end

payload = Yoti::DocScan::SessionSpecification.build do |specification|
  specification.with_user_tracking_id("<YOUR_USER_ID>")
    .with_requested_checks {
      Yoti::DocScan::SessionSpecification::RequestedCheck.build(specification.builder) do |requested_check|
        requested_check.with_type("ID_DOCUMENT_AUTHENTICITY").with_config
      end
      Yoti::DocScan::SessionSpecification::RequestedCheck.build(specification.builder) do |requested_check|
        requested_check.with_type("LIVENESS").with_config({liveness_type: "ZOOM", max_retries: 3})
      end
    }
end

response = Yoti::DocScan::Client.new.create_session(payload)

if error = response.error
  # Yoti::Errors::ErrorResponse
  puts error.message
end

session = Yoti::DocScan::Client::Session.from_json(response.body)

# Render the form
iframe_url = "#{Yoti.doc_scan_api_endpoint}/web/index.html?sessionID=#{session.session_id}&sessionToken=#{session.client_session_token}"

# Find an existing session
response = Yoti::DocScan::Client.new.get_session(session.session_id)
session = JSON.parse(response.body)
media_id = session.dig("resources", "id_documents").as_a[0].dig("document_id_photo", "media", "id").as_s

# Fetch specific media content
media = Yoti::DocScan::Client.new.get_media_content(session.session_id, media_id)
File.write("/path/to/document.png", media.content)
