This summary describes the integration of Twilio Flex and HubSpot CRM to enhance contact center operations, providing a personalized experience for agents and customers alike. The integration enables screen pops with customer information from HubSpot, improving agent efficiency and customer experiences through self-service journeys, intelligent routing decisions, and better data validation. To achieve this, developers must create a Twilio Function to fetch customer records from HubSpot based on calling or SMS/WhatsApp numbers, two Studio flows to invoke the function and parse responses, and a Flex plugin to embed HubSpot within Flex as an iframe for screen pops. The solution components include serverless functions, Twilio Studio flows, and a Flex plugin, which can be deployed using Twilio CLI tools.
