Conversation summary trigger events
End-of-conversation events
User/Agent Message propagation

Send all events to the same endpoint using the appropriate event name and payload structure.

Supported Events

Internal Transfer Event

Tracks agent join and exit actions, including cold and warm transfers.

Event Name

INTERNAL_TRANSFER_EVENT

Event Structure

{
 "name": "INTERNAL_TRANSFER_EVENT",
 "transfertype": "NA | COLD | WARM",
 "transition": "entry | exit",
 "isExtAD": true,
 "language": "en",

   "type": "agent",
   "customFields": {
     "agentEmail": "string",
     "queueId": "string",
     "queueName": "string"
   }
 }
}

Field Description

Field	Required	Description
transfertype	Yes	Transfer type: `NA`, `COLD`, or `WARM`.
transition	Yes	`entry` when agent joins, `exit` when agent leaves.
isExtAD	Yes	Indicates whether an external directory is used.
language	No	Conversation language.
experience	Yes	Interaction type (`chat` or `voice`).
participant	Yes	Agent details.
participant.customFields	No	Required only when using the Quality Module for post-call analysis.

Transfer Types

Type	When to Use
NA	First agent entry and final agent exit.
COLD	One agent replaces another. Only one active agent at a time.
WARM	Multiple agents participate simultaneously.

Transfer Flow Scenarios

Cold Transfer Flow

In this scenario, Agent-1 accepts the call and redirects it to Agent-2, and later Agent-3 gets the call.

Customer connects to Agent 1 → NA + entry
Agent 1 exits the conversation → cold + exit
Agent 2 accepts the conversation → cold + entry
Agent 2 exits the conversation → cold + exit
Agent 3 accepts the conversation → cold + entry
Conversation ends → Last agent → NA + exit

Warm Transfer Flow

Customer connects to Agent 1 → NA + entry
Agent 1 invites Agent 2 as a consultant
Agent 2 joins → warm + entry
Agent 1 invites Agent 3 as a consultant
Agent 3 joins → warm + entry
Agent 2 leaves → warm + exit
Agent 3 leaves → warm + exit
Conversation ends → Agent 1 exits → NA + exit

Redial Scenario

Customer connects to Agent 1 → NA + entry
- Conversation drops unexpectedly
Agent reconnects to the same conversation → redial + entry
- Conversation continues without creating a new segment
Conversation ends → Agent 1 exits → NA + exit

Trigger Summary Event

Triggers the generation of a conversation summary.

Event Name

TRIGGER_SUMMARY_EVENT

Event Structure

{
 "name": "TRIGGER_SUMMARY_EVENT",
 "data": {

 }
}

Field Description

Field	Required	Description
data.language	Yes	Summary language (for example, English).
data.locale	Yes	Locale code (for example, en).
data.type	Yes	Summary type (for example, `post`).

End of Conversation Event

Notifies Agent AI that the conversation has terminated.

Event Name

END_OF_CONVERSATION

Invoke this event only once, at the final termination of the conversation—whether normal or unexpected—to prevent duplicate processing.

Event Payload Examples

No Transfer

First Agent Accepts (INTERNAL_TRANSFER_EVENT) This event triggers when the first agent accepts the customer interaction (not a transfer). Entry Scenario: The system triggers this scenario when the Agent AI widget loads with transition as entry along with the agent details. Exit Scenario: The system triggers this scenario at the end of the interaction with transition as exit along with the agent details.

Standard Conversation Flow: Event Sequence

For any conversation lifecycle, the system must trigger the following events in the prescribed order to ensure accurate analytics, proper session tracking, and complete reporting within Kore.ai.

Step	Event	Transfer Type	Transition	Requirement	Description
1	`INTERNAL_TRANSFER_EVENT`	`NA`	`entry`	Mandatory	Marks the beginning of the conversation when the first agent accepts the interaction. This is the starting point for all conversations.
2	`INTERNAL_TRANSFER_EVENT`	`cold` / `warm`	`entry` / `exit`	Conditional	Include this event only if internal transfers occur during the conversation. Each transfer (cold or warm) must include the appropriate entry and exit events for the respective agents.
3	`INTERNAL_TRANSFER_EVENT`	`NA`	`exit`	Mandatory	Marks the final agent’s exit from the conversation. This must always be triggered before conversation closure.
4	`TRIGGER_SUMMARY_EVENT`	—	—	Conditional	Include this only if you need to generate a disposition summary. It triggers after the agent exits and before the conversation is formally closed.
5	`END_OF_CONVERSATION`	—	—	Mandatory	Signals the formal closure of the conversation. This must always be the final event in the sequence to ensure proper post-call analytics and Quality Management processing.

Key Rule: Every conversation must begin with Step 1 and end with Steps 3 and 5 at minimum. The system triggers steps 2 and 4 based on the conversation context (for example, transfers or summary generation).

Abrupt Conversation End (Redial): Event Sequence

When a conversation drops unexpectedly (for example, due to a network failure or system disconnection), you must follow this event sequence to re-establish the session and close it properly. The conversationId remains the same as the original dropped call to maintain session continuity.

Step	Event	Transfer Type	Transition	Description
1	`INTERNAL_TRANSFER_EVENT`	`NA`	`exit`	Registers the agent’s exit from the dropped conversation, formally closing the interrupted session.
2	`INTERNAL_TRANSFER_EVENT`	`redial`	`entry`	Marks the agent’s re-entry into the same conversation after reconnection. This event is also applicable when an agent initiates a callback without a prior active conversation.
3	`INTERNAL_TRANSFER_EVENT`	`NA`	`exit`	Marks the agent’s final exit once the reconnected conversation concludes.
4	`TRIGGER_SUMMARY_EVENT`	—	—	Triggers the generation of the Disposition Summary for the completed conversation.
5	`END_OF_CONVERSATION`	—	—	Signals the formal closure of the conversation. Ensures capture of all post-call analytics and Quality Management data.

In a redial scenario, keep the conversationId the same as the original dropped call. This ensures the system treats the session as a continuation, not a new conversation, and preserves the full interaction history for analytics.
