Secrets, versions and undo
Keys locked away and used by name; every published version kept; undo for adds.
Secrets
API keys and tokens for other services go on your server's Secrets page, locked away. A flow uses one by its name, so a key is never pasted into a message or shown again. Free: 25 secrets; Pro: 25 secrets; Max: 100 secrets; Enterprise: 500 secrets.
Versions
Publish keeps each version in History; open it from the flow's header to see an earlier one and restore it. How long history lasts: Basic 7 days, Pro 30 days, Max 365 days, Enterprise 365 days. Free has none.
Undo
The editor's Undo takes back changes to your draft, and Discard draft goes back to the live version. Adding a template or a ready-made bot gives an Undo that removes everything it made.
