Selecting a Region​

When creating a chatbot:

  1. Go to "Create Chatbot"
  2. Under "Advanced Settings"
  3. Select "Data Region"
  4. Choose your region
  5. Click "Create"
If any of your users are in the EU, choose European Union

A US chatbot stores and processes data in the US, so sending EU users' data to a US chatbot is an international transfer that you, as the chatbot owner, are responsible for. Choosing the EU region keeps that data in the EU. The creation screen shows this reminder next to the region choice.

Data region cannot be changed after chatbot creation.
