On-Start & On-End Hooks

View as Markdown

Trigger API webhooks at conversation boundaries, load user context before the agent speaks, and push results when the call ends.

On-start API config

Configure an on-start API to fetch user context before the conversation begins (CRM profile, open tickets, eligibility flags). Typical inputs include caller phone number and campaign metadata.

Response template mapping

Map on-start API fields into agent variables and user info:

  • Populate greeting variables (name, plan, locale)
  • Prefill known account details so the agent does not re-ask
  • Gate tools or states based on returned flags

See Variables & Personalization.

On-end API config

Configure an on-end API to push results after the conversation:

  • Disposition and outcome variables
  • Collected fields
  • Transcript or recording references (when available)
