Anatomy of an agent
Agents are created the first time a call references them: ingestion looks up the
provider’s external id and reuses the matching agent, or creates one if it’s
new. If a provider rotates external ids from call to call, Zelto can collapse
those onto a single agent with an org-level pattern, so you don’t accumulate
duplicates.
Agent activity
Click into an agent for a call-volume trend chart, an hour-by-day heatmap, and its most recent conversations, alongside its system prompt and the findings surfaced from its calls. When an agent has a decision tree and mapped calls, its Decision Tree tab also shows a flow diagram of how calls moved between the tree’s steps. It only includes steps that calls actually traversed, so it stays out of the way until mappings are available for that prompt version. Each agent can also post a daily status message to Slack — yesterday’s conversation count, at a time you choose — once Slack is connected.How calls reach an agent
Every payload Zelto receives lands in the append-only webhooks table first, then becomes a conversation with a turn-by-turn transcript. How each provider delivers a call:
Recording the raw payload first means ingestion is always replayable, so a
delivery is never lost even if processing has to be re-run.
Connection status
Each agent’s detail page carries a Connections card — the at-a-glance signal that calls are reaching Zelto. It names the provider the agent ingests from and reports on the last call received:- “Last call received 2 hours ago” — calls are flowing; ingestion is healthy.
- “No recent calls” / “integration may be stale” — connected, but nothing has arrived lately. Place a test call, or check that the provider is still sending.
- “Last webhook errored” — the most recent delivery reached Zelto but couldn’t be turned into a conversation.
- “No calls received yet” — the agent has a provider but has never received a call.
