Can we transfer our journey data to our database?

Architect does not support transferring the journey analytics data via any external API.

You can export your Architect Analytics along with the requested performance metrics through your Inone panel, or export the user activities or user information related to a specific journey. For example, you can export the profile IDs or email addresses of the users who entered a specific journey, or the profile IDs of the users who received email or web push messages from a specific journey.

You can use two different methods to export the data: Export Raw User Data API or user profiles. Follow the steps on How to export journey user data to get user filters, attributes, event details and filter users with the desired journey-related events.
