Human handoff, or human-in-the-loop (HITL), is what lets a Voiceflow WhatsApp agent hand a conversation over to a real person mid-chat - without the customer needing to repeat anything or move to a new channel. The customer keeps chatting in the same WhatsApp thread; only who's replying on the other end changes.
Voiceflow agents are strong at structured conversation design - guiding users through flows, qualifying leads, and answering common questions. But like any chatbot, a Voiceflow agent will eventually hit a question it can't resolve, or a customer who simply wants to speak to a person. Without a human handoff solution, that's usually where the conversation stalls or the customer gives up.
hitlchat connects directly to your Voiceflow project using your Voiceflow API key. Once connected, it monitors WhatsApp conversations for handoff triggers - HITL keywords typed by the customer, or an agent manually taking over - and when one fires, the bot pauses on that conversation and it's routed into a shared team inbox. Your agent replies from there, with the full bot conversation visible, and can hand control back to the Voiceflow agent once the conversation is resolved.
Integrating a human layer into your automated flows ensures that your customer experience remains high-quality even when automation reaches its limits.
Even a well-designed Voiceflow agent can't anticipate every question - handoff means there's always a way forward.
No redirect to email or a separate live chat tool, which keeps response times fast and the experience consistent.

Just as with Botpress, hitlchat supports two ways to connect a Voiceflow agent to WhatsApp. The right choice depends on your message volume and how quickly you need to launch.
Our general recommendation: Many agencies building Voiceflow assistants for clients start every new client on the QR code connection during the pilot phase, then migrate to the WhatsApp Business API once the client is ready to scale messaging volume or run broadcast campaigns. Both options use the same Voiceflow agent and the same hitlchat inbox - switching later is a configuration change, not a rebuild..

Setup takes only a few minutes using your existing, already-published Voiceflow agent - no rebuilding required.
Create a hitlchat account and start a free trial - no credit card required.
In the hitlchat dashboard, open Configuration and select Voiceflow as your integration type.
In Voiceflow, open your agent's Settings → API Keys, copy the API key, then paste it into the Voiceflow Configuration screen in hitlchat. Leave the Bot Active toggle enabled.
Connect your WhatsApp number using your existing WhatsApp Business API credentials or by scanning a QR code. No Meta approval is required for QR setup.
Add your HITL keywords (such as "agent" or "human") to automatically transfer conversations from the bot to your team.
Send a WhatsApp message to confirm your Voiceflow agent responds correctly, then test a handoff keyword to ensure the conversation reaches your hitlchat inbox.
Each agent gets Invite your team to the shared inbox. Each team member gets their own login, with access available on desktop and the hitlchat mobile app (iOS & Android).own login to the shared inbox, available on desktop and via the hitlchat mobile app (iOS & Android).
Every WhatsApp conversation your Voiceflow agent handles - along with every handoff - lands in the hitlchat shared team inbox. From there, agents can:
Agencies building Voiceflow agents for multiple clients often use hitlchat as a packaged human handoff layer they include with every project - each client gets their own inbox and team without needing direct access to the underlying Voiceflow project.
