Stories from real businesses

Daniel Ortega

eCommerce Ops Manager

"WhatsApp is where most of our online customer conversations happen. Our Voiceflow assistant handles the basic questions really well, but when questions get more complicated hitlchat allows our team to jump in instantly without having to move the customer to another channel. It feels like true live chat inside WhatsApp and we’ve seen higher conversions because of it"

Sanjay Mehta

Conversational AI Agency

"The hitlchat setup is super simple, and its easy to use! Most of our clients run small teams handling WhatsApp conversations powered by a Voiceflow bot. hitlchat gives them one shared workspace to manage all their conversations. Being able to step into bot conversations directly inside WhatsApp has transformed their support workflows."

Lucas Bennett

Voiceflow Developer

"We've been building Voiceflow WhatsApp assistants for our clients across various industries (healthcare, ecommerce, restaurants etc) for a few years now. We had been looking for a way to route conversations from the Voiceflow assistant to live human agent for some time. Eventually we found out about hitlchat and honestly its been a gamechanger for us ever since. Our clients love it, and as a result we love it!"

What Is Human Handoff? And How Does It Work With Your Voiceflow WhatsApp Agent?

Human handoff — often referred to as human-in-the-loop (HITL) — means passing a live conversation from an AI agent to a real team member, with no channel-switching and no asking the customer to start over.

For a Voiceflow WhatsApp agent, it works like this: the customer talks to your Voiceflow assistant as normal, and whenever the conversation calls for human judgment, a team member takes over and replies inside the very same WhatsApp thread.

This page covers the WhatsApp side of hitlchat’s Voiceflow human handoff platform — the same escalation layer is available for webchat as well.

Why it’s necessary

Voiceflow lets you automate most of your customer conversations — yet even the best-designed agent can’t handle every sale or support query end-to-end. Some moments still need a person:

Negotiating pricing or custom deals
Questions tied to a specific account
Upset or frustrated customers
Requests your agent wasn’t designed for

Without a handoff layer in place, those conversations stall — the customer drops off, switches channels, or gets stuck in a loop of repeated replies.

How Hitlchat works

hitlchat sits in the middle of your Voiceflow agent and WhatsApp, watching every conversation for a handoff trigger — a customer sending a HITL keyword such as “speak to a human,” or a team member stepping in from the inbox. When that happens:

Your Voiceflow agent is paused for that one conversation — all other chats stay fully automated.
The chat lands in your shared team inbox for a human to reply (on QR connections, you can even answer straight from the WhatsApp app).
When the issue is handled, the agent resumes — hand back manually, use a hand-back keyword, or let the inactivity timer do it automatically.

Since everything takes place on the same WhatsApp number, in the same thread, customers never see the seams of a handoff — the conversation simply becomes more helpful.

Why Add Human Handoff to your Voiceflow WhatsApp Agent?

Adding a human layer to your Voiceflow workflows means the customer experience stays strong even where automation runs out of road.

Stop losing high-value conversations

AI agents shine at FAQs and routing but struggle with judgment calls, objections, and edge cases — a handoff path means those chats don’t hit a dead end.

Keep the whole journey in WhatsApp

No bouncing customers to email or a separate live-chat widget — staying in one channel keeps replies fast and conversions up.

Give your team the full picture

Before anyone replies, they can read the entire Voiceflow conversation history — customers never have to explain twice.

Turn WhatsApp into a true sales & support line

With humans able to step in, WhatsApp graduates from “just the bot” to a genuine live sales and support channel.

Spot where your agent needs work

The conversations that trigger handoffs most often show you exactly which Voiceflow workflows are worth improving.

Voiceflow WhatsApp Business API vs QR Code: Which Should You Use?

There are two ways to connect Voiceflow to WhatsApp in hitlchat. Many teams begin on the QR code connection to test quickly, then switch to the WhatsApp Business API when it’s time for production.

Feature	WhatsApp Business API	QR Code
Best for	Production workloads, high chat volume, broadcast campaigns	Testing, demos, smaller teams, modest volume
Where agents reply	hitlchat inbox on web or mobile app	hitlchat inbox, or straight from the WhatsApp app on your phone
Message volume limits	Built to scale to high volumes reliably	Recommended for small-to-moderate volumes
WhatsApp number used	A dedicated Business API number	Your existing WhatsApp number (personal or business)
Bulk broadcast campaigns	Full support	Works, at reduced send volumes

Our advice: prove out your Voiceflow WhatsApp handoff on the QR connection first, then graduate to the WhatsApp Business API when message volume grows or you want production-scale broadcast campaigns. Switching is painless — your Voiceflow agent stays untouched; you only change the WhatsApp connection inside hitlchat.

How to Connect Voiceflow to WhatsApp with hitlchat

You can be up and running in minutes. A couple of steps differ depending on your connection method — WhatsApp Business API or QR code (compared above) — but the overall flow looks like this:

Sign up for hitlchat

Create your hitlchat account and start a free trial — no credit card needed.

Select your integration

From the hitlchat dashboard, go to Configuration and pick Voiceflow as your integration type.

Link Voiceflow

In Voiceflow, open your agent’s workflow, click the Settings icon, then API Keys — copy your Voiceflow API key and paste it into hitlchat. No changes to your agent needed.

Connect WhatsApp

Attach your WhatsApp number — sign in with Facebook, enter your existing WhatsApp Business API credentials, or scan a QR code with your phone.

Set your handoff triggers

Add HITL (human-in-the-loop) keywords — the phrases that should pull a human in, like “agent,” “human,” or “talk to a person.”

Run a test

Message your connected WhatsApp number to check the Voiceflow agent responds, then send a HITL keyword and watch the chat arrive in your hitlchat inbox.

Bring in your team

Every teammate gets their own login to the shared inbox — on desktop or the hitlchat mobile app (iOS & Android).

Managing Voiceflow WhatsApp Conversations from a Shared Inbox

After connecting, every WhatsApp chat your Voiceflow agent handles — plus every handoff — flows into the hitlchat shared team inbox, where your team can:

Review the complete conversation history, agent messages included, before jumping in
Respond with text, media, documents, and WhatsApp message templates
Pass a chat to a teammate with the full context intact
Return the conversation to your Voiceflow agent once it’s wrapped up
Organize contacts with tags and labels for follow-up and reporting

Your sales and support team never needs to open Voiceflow or dig through transcripts to work with WhatsApp — everything happens in one unified inbox.

Frequently Asked Questions

Everything you need to know about human handoff for Voiceflow WhatsApp.

Does hitlchat use the official WhatsApp Business API?

Yes — for production connections hitlchat uses the official WhatsApp Business API. There’s also a QR code option that needs no Meta credentials at all: just scan and go.

Do I need to rebuild my existing Voiceflow agent?

No. hitlchat connects to the Voiceflow agent you already have — you simply paste your Voiceflow API key into hitlchat. Your workflows in Voiceflow stay exactly as they are.

How does my Voiceflow agent know when to hand off to a human?

Two ways: automatically, when a customer types one of your HITL keywords (like “human” or “speak to an agent”), or manually, when a teammate takes the conversation over from the inbox.

Can the Voiceflow agent take back over after a human has replied?

Yes. Once the conversation is wrapped up, control returns to your Voiceflow agent — hand it back from the inbox, send a hand-back keyword, or let your inactivity timer re-engage it automatically.

How many team members can work in the shared inbox?

From one user on the Solo Agent plan up to 30 users on Enterprise — the shared WhatsApp inbox works for teams of every size.

Can my team reply from mobile, or only from a desktop?

Both work. There’s a hitlchat mobile app for iOS and Android alongside the web inbox — and on QR connections, replies can even come straight from the WhatsApp app.

Does hitlchat support Voiceflow webchat as well as WhatsApp?

Yes. The same Voiceflow agent can offer human handoff on WhatsApp and on your website’s webchat widget, all managed from one shared inbox.

What about conversations my Voiceflow agent already handles well?

They’re untouched — the agent keeps answering those automatically. A handoff only happens when a HITL keyword fires or a teammate steps in, so your best-performing workflows keep running.

Can I send WhatsApp marketing campaigns from the same number?

Yes — hitlchat has a built-in WhatsApp bulk messaging tool, so broadcast campaigns go out from the same number your Voiceflow handoff runs on.

How quickly can I get set up?

A QR code connection takes about two minutes. The WhatsApp Business API route takes a bit longer — you’ll sign in with Facebook or enter your Meta API credentials — and it’s a one-time job.
