One of the biggest hesitations about moving to the API is losing the familiar WhatsApp Business app. Coexistence removes that worry: it lets you keep using the app on your phone while also connecting the official WhatsApp Business API on the same number. Here is how it works and when it makes sense.
What coexistence actually means
Instead of a hard migration, your number works in both places at once.
- Your team keeps replying from the WhatsApp Business app as before.
- A platform connects the same number to the API for broadcasts and automation.
- Recent chat history can carry over so context is not lost.
- Messages sent from either side appear in a shared view on the platform.
What you gain
Coexistence is a gentle on-ramp to the API's power without an abrupt change.
- Scheduled broadcasts beyond the app's 256-contact limit.
- A visual chatbot and automated flows.
- A shared inbox so several agents handle the same number.
- Reporting on delivery and replies the app does not offer.
What to keep in mind
It is a bridge, not a loophole. Business-initiated messages still need approved templates, Meta's conversation charges still apply, and consent rules in our compliance guide do not change. Over time, most teams lean on the platform more and the app less.
Who should use it
Coexistence suits teams nervous about change, or those where field staff rely on the app while head office runs campaigns through the API. If you want a clean break instead, a standard migration is still available.
Frequently asked questions
Can I use the WhatsApp Business app and API on the same number?
Yes. Coexistence connects the official API to a number that is still active in the WhatsApp Business app, so your team keeps replying in the app while the platform adds broadcasts, automation and a shared inbox.
Will I lose my chat history?
Recent conversation history can carry over when you set up coexistence, so agents keep context. Exact behaviour depends on the setup, but the goal is a smooth transition rather than a reset.
Do template and pricing rules still apply?
Yes. Business-initiated messages need approved templates, and Meta's standard conversation charges apply regardless of whether a message is sent from the app or the API.
Is coexistence permanent or temporary?
It can be either. Many teams use it as a transition and gradually shift to the platform, but you can keep both running as long as it suits your workflow.
