The WhatsApp Business App is free and easy to use, ideal for managing low volumes of messages, but limited in users and features.
Businesses needing more powerful capabilities should consider the WhatsApp API, a scalable solution enabling automation, multi-user access and third-party integrations for managing high volumes of conversations and data.
The WhatsApp API doesn't include an inbox to send and receive messages, so you'll need a customer conversation platform like respond.io that provides one.
Because switching to WhatsApp API can feel daunting, respond.io supports WhatsApp Coexistence. This means you can connect to the WhatsApp API while still using your WhatsApp Business App with the same phone number.
Here’s what’s in it for you.
Unsure if WhatsApp API is for you? Test it on respond.io and keep your Business App running.

✅ For you
❌ Not for you
No. Respond.io is a customer conversation platform and an official WhatsApp Business Solution Provider. Your team answers WhatsApp, Instagram, TikTok, Facebook Messenger, email and phone calls in one inbox.
Not if one person handles under 500 conversations a month: the free WhatsApp Business App usually covers that. Respond.io is worth it once several people share the number, ad chats outpace your replies, or you need AI Agents.
The WhatsApp Business App is free for one phone plus up to 4 linked devices. The WhatsApp API lets many people work from one number with automation and integrations, and Meta charges per message. It has no interface of its own, so you use it through a platform like respond.io.
No. Meta charges per delivered message: templates by category and country, and service messages after the first 1,000 per number each month. Incoming messages are free, and respond.io adds no markup.
From 5 to unlimited, depending on your respond.io plan. Everyone works from the same WhatsApp number, and you can add users for a monthly fee.
Yes. On respond.io, AI Agents handle WhatsApp chats on their own, following your instructions, and also work on Instagram, TikTok and Facebook Messenger.
Yes. Respond.io has native integrations with HubSpot, Salesforce and Google Sheets, and connects to other tools through Zapier and Make.

Yes, respond.io supports WhatsApp coexistence, allowing you to use a single phone number for WhatsApp Business App and WhatsApp API simultaneously. You have the flexibility to test or transition to WhatsApp API gradually without giving up WhatsApp Business App.
No. Contacts still message the same number, and new messages appear in both respond.io and the app. A few app features, such as disappearing messages, turn off in 1:1 chats, and calls and group chats don’t reach respond.io.
