WhatsApp Business Multiple Users: The Ultimate Guide
How to Use WhatsApp Business App vs WhatsApp API for Multiple Users (2025 Guide) | Respond.io

TL;DR - How to Use WhatsApp Business for Multiple Users

Use a single WhatsApp Business number with multiple users for seamless customer communication.

  • WhatsApp Business App: Supports up to 5 devices for micro and small businesses.

  • WhatsApp Business App + Meta Verified: Supports up to 10 devices for businesses outgrowing the WhatsApp Business App.

  • WhatsApp Business API: The best WhatsApp solution for growing businesses that require unlimited users, agent performance tracking, CRM integration, and advanced automation.

  • WhatsApp Coexistence: Use WhatsApp Business App and WhatsApp API on the same phone number to test if the API is right for you.

Here’s a common scenario: Your business is scaling well, so you decide to hire more agents and add them to your WhatsApp account. Suddenly, you realize it is not that simple, and some questions arise. How to add more users to WhatsApp? What is the limit? Do I have to pay to add more users? In this WhatsApp Business multiple users guide, we will cover all you need to know to add as many WhatsApp users as you need for your business.

WhatsApp Business Multiple Users for Micro and Small Businesses

The WhatsApp Business App allows a business number to be used on up to five devices—one primary phone and four linked devices. This is ideal for small businesses that need multiple team members to respond to customer messages from anywhere.

The app setup process is straightforward and businesses can use it for free. Plus, it includes business tools like greeting and away messages, WhatsApp catalog, WhatsApp Pay and quick replies.

For businesses that need to use WhatsApp on more than 5 devices, Meta Verified lets you connect up to 10 devices and assign chats to specific agents. However, this plan is only available for users in certain countries.

Despite being a convenient and easy-to-use solution, the WhatsApp Business App is not always the best choice. Let’s see why.

Limitations of WhatsApp Business App for Multiple Users

Using WhatsApp Business App with multiple devices is convenient for small businesses, but this is only a temporary solution or feasible when your business is starting. As your business expands, you’ll soon encounter problems with using linked devices, such as:

  • Can’t ensure all customers have been answered

  • No way to organize chats, such as marking a chat as resolved

  • Can’t track agent workload or performance

  • Can’t connect to a CRM, as WhatsApp Business app doesn’t support any CRM integration

  • No user access controls and all the data can be accessed by every agent

  • Not able to implement advanced automation

If your team size stays the same, having 5 to 10 devices connected to one WhatsApp number is sufficient. As your business grows, you’ll need a more sophisticated platform to handle more agents, contacts and messages. This is where WhatsApp API comes in.

WhatsApp Business API for SMBs, Mid-size Companies and Enterprises

WhatsApp API (also known as WhatsApp Business Platform) is designed for SMEs and large businesses that want to scale and manage their teams, messages and customers more effectively.

WBMU - 2

Here’s the best thing: WhatsApp API supports an unlimited number of users. No matter how big your business is or how fast it grows — WhatsApp API won’t let you down. Still, there are some basic things to keep in mind about WhatsApp API.

How Does WhatsApp API Work for Multiple Users?

While WhatsApp API is the ultimate solution for WhatsApp Business multiple users, it is also more complex. Let’s start with the fundamentals.

A WhatsApp BSP (Business Solution Provider) is a company authorized by Metato give businesses access to WhatsApp API. BSPs like respond.io help businesses integrate WhatsApp into their workflows successfully and often provide additional features.

Signing up for WhatsApp API with respond.io is quick and easy. The entire process takes only a few minutes – from linking your Facebook Business Account (now known as Meta Business Portfolio) to adding a phone number.

Meta has rolled out new WhatsApp Setup Guidance directly inside your Meta Business Portfolio. This new hub provides step-by-step instructions to simplify your API setup and manage message eligibility. You can now launch campaigns faster with pre-approved templates and instantly check your template review and appeals status.

Because respond.io is also a customer conversation management software that comes with a sales inbox, you can start messaging customers right after creating your WhatsApp API account. That’s killing two birds with one stone!

Once you get a basic command of WhatsApp API, you’ll experience its many benefits.

Benefits of Using WhatsApp API for WhatsApp Business Multiple Users

The WhatsApp Business App limitations don’t exist with WhatsApp Business API. These are some of the main improvements you’ll see after making the switch.

  • Never miss a customer inquiry – Every message can be answered with automation and team-wide visibility.

  • Stay organized with chat management – Mark conversations as resolved, assign chats, and keep track of ongoing interactions.

  • Monitor agent performance – Get insights into workload, response times, and agent efficiency.

  • Seamless CRM integration – Sync WhatsApp with your CRM to track customer interactions and sales.

  • Control user access – Restrict data access based on roles to keep customer information secure.

  • Advanced automation for efficiency – Automate replies, lead qualification, and customer follow-ups for faster service.

While it’s not required to get started, growing businesses may want to get verified as an official account with WhatsApp green tick.

Despite the many advantages of the WhatsApp API, some businesses hesitate to make the switch from the WhatsApp Business App. They’re comfortable with what they know and may be wary of stepping into unfamiliar territory. If that sounds like you, we’ve got good news.

Do I Have to Choose Between WhatsApp Business App and API?

Until recently, businesses had to choose between using the WhatsApp Business App or the WhatsApp API. Now, with WhatsApp Coexistence, you can use both on the same number.

This means you can keep your existing WhatsApp Business app number and still connect it to the WhatsApp Business Platform (Cloud API) via respond.io — without losing access to your app or needing a new number.

Why WhatsApp Coexistence Matters for Teams

Coexistence gives your team the flexibility to:

  • Use advanced API features like multiple users, automation, AI routing and CRM integrations via respond.io.

  • Keep using the WhatsApp Business app for simple 1:1 conversations or business tools like catalogs and quick replies.

  • Maintain your existing number, customer chat history and app access—even after connecting to the API.

This setup is perfect for growing teams who want the power of WhatsApp API without giving up the convenience of the app they’re used to.

⚠️ Note: Some WhatsApp Business app features like calls, group chats, broadcast lists and disappearing messages won't work on the API side. Also, if you enable coexistence, you’ll temporarily lose the green checkmark (you can reapply after setup).

Next, let’s discuss setting up WhatsApp with multiple users on the WhatsApp Business app and WhatsApp API.

FAQ and Troubleshooting

Is WhatsApp Business multiple users free?

The WhatsApp Business App allows free use on up to five devices. If you wish to use WhatsApp on up to 10 devices, you can pay for a WhatsApp Premium subscription.

For businesses requiring more than ten users, WhatsApp API is the solution. This, however, involves WhatsApp’s template message fees and the use of a messaging software, which incurs additional costs. You'll need to subscribe to a WhatsApp BSP, some of which add on set-up and monthly connection costs. For example, Sleekflow charges $15 per WhatsApp number per month. With respond.io, you'll only need to pay based on WhatsApp conversation fees, with no markups or add-on fees.

Can I use WhatsApp Business on 2 phones?

Yes, you can. The WhatsApp Business App supports up to five devices, including four linked devices and one phone per account, but not on two phones simultaneously. On WhatsApp API, there is an unlimited number of users and devices.

How to use WhatsApp Business on multiple devices?

  1. Open your WhatsApp Business App on your primary phone.

  2. Tap the More Options menu (three vertical dots) in the top-right corner.

  3. Select Linked Devices.

  4. Choose Link a Device.

  5. Scan the QR code displayed on the screen of the device you want to link

What happens to my message history when I switch devices?

When you use WhatsApp Business on a new device, your old messages don’t transfer automatically because of WhatsApp’s security rules. However, once you link the new device, some recent messages may sync and become available.

Is my data safe when using WhatsApp Business on multiple devices?

Yes! WhatsApp Business keeps your chats secure with end-to-end encryption, even when you use multiple devices. This means your messages and business information stay private and can’t be read by anyone else.

Can AI Agents answer business calls?

Yes, AI agents can answer voice calls if you use the right tool. On respond.io, you can configure the AI agent’s voice, add instructions and test the experience before going live. This gives you full control over how calls are handled. Unlike standalone voice bots, respond.io’s AI Voice Agent is fully integrated into a unified inbox, allowing businesses to manage messaging and voice interactions in a seamless thread with every customer, with shared logs and reporting.

How can I use AI Agents to follow up on customer conversations?

If conversations are left hanging pending a customer’s response, you can set your AI Agent to nudge them with a relevant follow-up question. For example, respond.io’s AI Agent goes beyond simple time-based nudges or workflow triggers. It uses conversation history to understand its context and determines when and how to follow up. This understanding helps it avoid contacting customers whose issues are already resolved, and to send personalized, human-like nudges at the right time.

Can I get transcripts from customer phone calls?

Yes. With respond.io, VoIP and WhatsApp Business API calls can be automatically transcribed into clear, searchable records. Each call transcript includes speaker names, timestamps and full text, so managers can quickly review conversations without listening to entire recordings. This feature is limited to specific plans.

These transcripts make it easy to audit agent performance, spot coaching opportunities and train new staff with real examples from actual calls. They’re also valuable for compliance and accountability, since all transcripts are securely stored in-platform and can be accessed through the Contact Drawer or Reports Module. This gives managers full visibility across teams and supports consistent, data-driven quality control.

Can AI Agents understand and respond to audio messages?

Yes. Respond.io’s AI Agents can now process voice notes and audio recordings sent by customers across supported messaging channels. The platform automatically transcribes audio into text and integrates it directly into the AI Agent’s conversation context. This means the AI can understand the intent, nuance, and details of spoken messages and respond naturally, maintaining a seamless conversational flow, whether the customer prefers typing or speaking.

This feature is especially valuable for voice-first users, common in regions like the US, LATAM and Southeast Asia, where people frequently communicate via voice notes.

How can I transfer customer calls to another agent?

To transfer a call, you’ll need a business communication or call management platform that supports call forwarding. With it, you can move an ongoing conversation to another agent or phone number without disconnecting the customer. On respond.io, you can transfer calls on WhatsApp Business Calling API and other VoIP channels to your teammates or agents in other departments. Call recordings and transcripts remain intact during a transfer, so customers experience a smooth handoff while agents gain full conversation history for context.

How can AI Agent chats feel less robotic and more human?

AI Agents on respond.io hold natural, human-like conversations by understanding intent, context and tone, not just following scripts. They chat fluidly across WhatsApp, Messenger, Instagram, TikTok and more, drawing context from conversation history and responding according to your rules or criteria.

  • To make them sound even more human:

  • Define an AI persona with a tone that fits your brand.

  • Use typing indicators to mimic real response pauses.

  • Add short reply delays to avoid instant, bot-like answers.

  • Feed it quality sources so responses are accurate and contextual.

  • Allow human handoff for complex or sensitive topics.

The result: fast, natural conversations that feel genuinely human — even when they’re not.
