End function

The End function is executed at the conclusion of a conversation, enabling final data processing, cleanup, and integration tasks. It runs asynchronously, meaning it does not delay the end of the call but ensures that any necessary post-conversation operations are completed.

Key features and functionality

1. Asynchronous execution: Allows the assistant to finalize data and trigger follow-up processes without interrupting the user experience.

2. Post-conversation data handling: Captures and processes important details from the conversation for reporting, logging, or integration.

3. Customizable workflows: Supports integration with external systems, enabling seamless handoffs and automated follow-ups.

Use cases

The End function:

1. Logs conversation metadata

• Save key conversation details, such as duration, topic, or sentiment analysis, to a database or CRM.

• Example use case: Track customer service interactions for reporting and performance analysis.

2. Triggers workflows

• Start processes like creating support tickets, sending confirmation emails, or updating account records.

• Example use case: Automatically notify the sales team about potential leads from the conversation.

3. Schedules follow-ups

• Prepare reminders, SMS notifications, or callbacks for unresolved queries.

• Example use case: Send a confirmation SMS after booking an appointment or a callback request.

Implementation example

Below is a Python implementation of the End function:

def end_function(conv: Conversation):
    # Log metadata
    metadata = {
        "conversation_id": conv.id,
        "duration": conv.duration,
        "topic": conv.state.get("last_topic", "Unknown"),
        "sentiment": conv.state.get("sentiment", "Neutral"),
    }
    log_to_crm(metadata)

    # Trigger external API
    if conv.state.get("support_needed"):
        create_support_ticket(conv.state.user_id, metadata)

    # Schedule follow-up if necessary
    if conv.state.get("follow_up_required"):
        schedule_follow_up(conv.state.user_id, conv.state.follow_up_time)

    return "End function executed successfully."

Best practices for End function design

1. Efficient execution:

   • Design the function to complete quickly to avoid slowing down post-conversation processes.

2. Error handling:

   • Ensure errors during execution do not disrupt downstream workflows.

   • Implement fallback mechanisms for failed API calls or missing data.

3. Data consistency:

   • Validate and sanitize data collected during the conversation before processing or logging it.

4. Relevance:

   • Include only necessary post-conversation tasks to maintain efficiency and focus.

Examples: Enhancing post-conversation workflows

📊 Data logging for analytics

Capture details like customer sentiment, topics discussed, and the resolution status for reporting and analytics.

Example:

• “Logged: Customer expressed interest in our premium plan and showed positive sentiment.”

📞 Automatic follow-ups

Send reminders, confirmation messages, or escalation notices to keep the customer informed.

Example:

• “An email has been sent confirming your booking for January 10th.”

🛠 Task automation

Streamline processes by triggering external workflows or integrations.

Example:

• “Support ticket created: Issue with account login noted during the conversation.”

🧾 CRM updates

Ensure customer records are up to date with the latest interaction details.
