We’re excited to announce that new Google Chat Import Mode APIs are now available in the Developer Preview Program! Import Mode allows developers to import data from other messaging systems while maintaining historical timestamps for messages and spaces. Data from large channels can be copied into Chat spaces silently without notifying the user, sending emails, etc until the admin is ready to have users start using the new space in Chat.
Google are continuing to add developer features to the Google Chat platform, the latest being Import Mode APIs. Theses APIs are designed to help when transitioning from other messaging platforms to Google Chat. Google highlight the following advantages of the new Import Mode APIs:
Preservation of resource creation timestamps. You can set a historical time for the creation times of space and message resources, letting Chat apps retain historical context during user adoption of Google Chat.
End users can’t view or access spaces in import mode. To prevent user interference of a space undergoing data import, or to avoid possible user confusion as a result of viewing an in-progress data import, spaces in import mode are hidden from end users. After a space has completed import mode, you can add users to the space.
Chat turns off notifications during import mode, so that users can avoid unnecessary alerts about the migration. [Ref]
The new Import Mode APIs are currently in Developer Preview and if not already part of the preview program the linked page includes information on how to join.
