Review traffic history
Traffic history is the record of every traffic split an assistant has had, newest first. Each entry shows which versions the split routed calls to and at what share, the note left with the change, when it took effect, and who made it. Use it to answer questions like “when did v7 go to 50%?” or “who rolled back last night, and why?”, and to jump straight to how any recent split performed.
Nothing in the history is ever edited or removed. Each change to a split adds a new entry, and the newest entry is the one routing calls.
Open traffic history
Dashboard
API
Entries are grouped by the day they took effect, such as Today, Yesterday, or a date. Select Load more at the bottom of the panel to see older entries. An assistant that has never had a split shows No traffic history yet, because every call still goes to the latest published version.
Read an entry
Each entry in the panel shows, from top to bottom:
- The split: each version with its share, such as
v690% andv710%, or Follows the latest version when the assistant routed every call to its latest published version. The entry in effect now is marked Current. - The note: the description left with the change, if one was given.
- When and who: the time the split took effect and who made it. Changes made through the API show API key. Changes Vapi made on its own, such as moving a follow-latest assistant to a version you just published, show Vapi.
Leave a note every time you change a split, such as “canary: tightened refund prompt” or “rollback: v8 transfers spiking”. Notes appear in the history and in the API, so whoever looks next, including you, knows why the split existed.
See how a split performed
Select an entry to open the Traffic tab over exactly the window that split governed, from when it took effect until it was replaced. The entry the tab is showing stays highlighted, so the panel works as a second way to pick the tab’s range.
You can open the current split and the five before it this way, the same splits the Traffic tab’s range menu offers. Older entries stay in the history as a record but can’t be opened on the tab. To read metrics for an older split, request its window with Get traffic split metrics, using its createdAt as from and the next split’s createdAt as to.
Change the current split
The current entry has an Edit split button (the pencil). Select it to open the traffic editor on today’s routing, the same editor the Traffic entry in the assistant header opens. Saving a change adds a new entry to the top of the history; the old one stays as it was.
