Home tab views

The Home tab is available only for Bolt apps, not apps created with the Deno Slack SDK. Home tab view objects are used within the views.publish Web API method.

Non-standard characters (including characters with diacritics) within view objects are converted and sent in unicode format when you receive the view callback payloads.

Preserving input entry in views

Data entered or selected in input blocks can be preserved while updating views. The new view that you use with views.update should contain the same input blocks and elements with identical block_id and action_id values.
