Using an existing number for the WhatsApp Business API

If you are not yet using the WhatsApp Business API, but you have a number that is active on the WhatsApp app or the WhatsApp Business app, it is possible to take that number with you to Trengo and use it for the WhatsApp Business API.

💡 If you are already using the WhatsApp Business API via Twilio or Messagebird, read here how you can connect them to Trengo.

Activate the number in Trengo

If you want to keep a WhatsApp Consumer number or WhatsApp Business number, you should keep in mind that the number must be temporarily removed in order to activate it in Trengo. You cannot receive messages during this time as the number will be offline but don't worry! You will be up and running in a matter of minutes again.

Note: Removing the number from the WhatsApp application will mean that all existing conversation history you have in the WhatsApp (Business) app will be lost.

Transfer chats to Trengo

It is not possible to take existing conversation history in your WhatsApp (Business) app with you to Trengo. However, it is possible to transfer all telephone numbers and names using a CSV file. In this article you can read how you can do this.

Enjoy using the WhatsApp Business API in Trengo!
