Great question! You're right that the export/restore API doesn't handle fulfillment or Google Assistant integration settings since those aren't included in the agentContent blob. Here are the direct API-based solutions to automate these two parts:

You can use the Dialogflow Fulfillments API to directly update your fulfillment configuration, including the webhook URL. This avoids relying on the export/restore flow entirely for this step.

Here's a practical Python example using the official google-cloud-dialogflow library:

from google.cloud import dialogflow_v2beta1 as dialogflow

def set_fulfillment_webhook(project_id, webhook_url):
    client = dialogflow.FulfillmentsClient()
    parent = client.project_agent_path(project_id)

    # Fetch existing fulfillment settings to preserve other configurations
    current_fulfillment = client.get_fulfillment(parent=parent)
    
    # Update only the webhook URI while keeping other settings intact
    current_fulfillment.generic_web_service.uri = webhook_url
    current_fulfillment.enabled = True  # Ensure fulfillment is active

    response = client.update_fulfillment(
        fulfillment=current_fulfillment,
        update_mask="generic_web_service.uri,enabled"
    )
    print(f"Fulfillment webhook updated successfully: {response}")

# Usage
set_fulfillment_webhook("your-gcp-project-id", "https://your-production-webhook.com/dialogflow")

This approach lets you modify just the webhook URL without overwriting other fulfillment settings (like Cloud Functions triggers) you might have in place.

For Google Assistant-specific settings (invocation name, welcome intent, privacy policy URL, etc.), use the Dialogflow Google Assistant Settings API. This API lets you automate all the configuration you'd normally do in the Dialogflow console's "Integrations" tab for Google Assistant.

Example Python code to update key Assistant settings:

from google.cloud import dialogflow_v2beta1 as dialogflow

def update_assistant_integration(project_id, invocation_name=None, privacy_url=None):
    client = dialogflow.GoogleAssistantSettingsClient()
    parent = client.project_agent_path(project_id)

    # Fetch current settings to avoid overwriting existing configs
    current_settings = client.get_google_assistant_settings(parent=parent)

    # Update specific fields as needed
    if invocation_name:
        current_settings.invocation_name = invocation_name
    if privacy_url:
        current_settings.privacy_policy_url = privacy_url

    # Define which fields to update (prevents accidental overwrites)
    update_fields = []
    if invocation_name:
        update_fields.append("invocation_name")
    if privacy_url:
        update_fields.append("privacy_policy_url")

    response = client.update_google_assistant_settings(
        google_assistant_settings=current_settings,
        update_mask=",".join(update_fields)
    )
    print(f"Google Assistant settings updated: {response}")

# Usage: Set a custom invocation name and privacy policy URL
update_assistant_integration(
    "your-gcp-project-id",
    invocation_name="my custom assistant",
    privacy_url="https://your-site.com/privacy"
)

Key Notes for Both Workflows #

• Permissions: Your service account needs the Dialogflow Admin role (for fulfillment changes) and Actions Editor role (for Assistant integration tweaks) in your GCP project.
• API Enablement: Make sure both the Dialogflow API and Actions API are enabled in your GCP project's API library.
• Idempotency: Always use the update_mask parameter when modifying settings—this ensures you only change the fields you intend to, avoiding accidental overwrites of existing configurations.
