Chat with customers right where you work, in an embedded window inside the HubSpot Contact card, without switching screens. No WhatsApp Business API required, you connect your own number with a QR code. Every incoming and outgoing message is logged to the contact timeline.
Setup takes minutes, with no code.
Handle customer conversations exactly where you already work, inside the HubSpot record.
FlexInbox connects your HubSpot account with secure authorization and adds an embedded WhatsApp and Telegram chat window to every contact record. Your agent writes to the customer from inside the record, messages flow live, and there is no need to switch screens.
This is what sets FlexInbox apart from HubSpot's native WhatsApp: no WhatsApp Business API required. The agent connects their own number by scanning a QR code, just like WhatsApp Web, with no costly API setup, no approval process and no per-number fee.
If an incoming number is not in HubSpot, the contact is created automatically and matched to the right card. Every incoming and outgoing message is logged as a note on the contact timeline, so the full history lives in one place and you always know which agent said what.
Everything your sales and support team needs to talk to customers, right inside the HubSpot record.
The live chat window opens inside the contact record, so you reply without ever leaving HubSpot.
Incoming numbers are matched to existing contacts, or a new contact is created and linked to the right card.
Incoming and outgoing messages are written to the timeline, so you never lose track of past conversations.
Both channels share one inbox, separated by channel badges, all tied to the same HubSpot record.
Your team shares a single number, and every message clearly shows which agent sent it.
An AI agent that speaks only from your knowledge answers common questions, in suggestion, semi or fully automatic mode.
No code, set up in minutes.
Link your HubSpot account to FlexInbox with secure authorization so the chat window appears on contact cards.
Connect your WhatsApp or Telegram account by scanning a QR code, with no WhatsApp Business API needed.
Write to the customer from inside the Contact card, and incoming and outgoing messages log to the timeline automatically.
Let the AI answer common questions, and have your agent take over only when needed. The AI speaks only from your knowledge base and never makes things up.
Fed from plain text, website crawling, FAQs and files (PDF, DOCX, CSV), it answers only with what it knows.
Suggestion mode drafts replies, semi-automatic answers by confidence threshold, fully automatic handles end to end.
On low confidence, a keyword or a customer request it hands off to an agent, and the AI goes quiet once a human replies.
