Changelog

17 September 2026#

Rating & Feedback#

We have introduced Rating & Feedback to help you understand how visitors feel about their conversations with your AI agent.
You can now:
Collect 1–5 star ratings and optional written feedback from visitors
Review feedback for individual conversations and open the linked chat for context
View each agent’s overall rating, total ratings, and score distribution
Enable feedback collection for each agent and configure when it should ask for a rating
A new Conversation Rating section on the Dashboard gives you a quick overview of customer satisfaction. You can also explore ratings by score and time period to identify what is working well and where your agent can improve.
Important: Feedback collection is available in web chat only.
To configure this, open your agent and go to Ratings > Settings. To review ratings and feedback, open Ratings or Dashboard > Conversation Rating.

Function Tool Call#

We have introduced Function Tool Call to help AI agents connect with external APIs and perform actions during conversations.
You can now:
Create custom tools for your AI agent
Connect APIs using GET, POST, PUT, and DELETE
Configure authentication, required inputs, and visitor approval
Test API requests before enabling a tool
Import and export tool configurations across agents
This allows your AI agent to perform tasks such as checking order status, retrieving account information, creating support tickets, or updating external systems.
To configure this, go to Install & Integrations > Function Tool Call.

Human Handoff#

We have introduced Human Handoff to help customers reach your team whenever human assistance is required.
You can now:
Define when the AI agent should offer human assistance
Allow customers to contact your team through Phone, WhatsApp, Email, Calendar, or Custom Instructions
Configure different contact details for each option
Notify your team when a customer requests human support
Review all handoff requests from the Handoff Requests section
This makes it easier for the AI agent to continue handling conversations while still giving customers a clear way to reach a person when needed.
To configure this, go to Human Handoff > Settings.

AI Agent Webhooks#

We have introduced AI Agent Webhooks to help you send important chatbot events to your own applications, CRM, support tools, or automation workflows.
You can now:
Create multiple webhooks for each AI agent
Configure the webhook Name, URL, Secret, and Timeout
Select which events should trigger each webhook
Send event data automatically to your connected system
Use a webhook secret for payload verification
Supported events include:
Session End
Human Handoff
Lead Capture
To configure this, open your AI agent and go to Webhooks.

Conversation Session End Based on Inactivity#

We have introduced Conversation Session End Based on Inactivity to give you more control over when a conversation should be considered complete.
You can now:
Set the inactivity period in minutes
Automatically end a session after the configured period
Trigger Session End webhooks when the session is completed
Manage the inactivity timer from Event Timers
The Session End timer belongs to the event itself, so changing it updates every webhook on that AI agent using the Session End event.
You can find this setting under AI Agent > Webhooks > Event Timers.
This is useful for post-conversation workflows such as CRM updates, analytics, follow-ups, or storing completed conversation data.

Lead Email Notifications#

We have introduced Lead Email Notifications so your team can be notified as soon as an AI agent captures a new lead.
You can now:
Enable or disable notifications for each AI agent
Add up to 5 notification email addresses
Send lead notifications to multiple team members
Configure different recipients for different AI agents
Receive captured lead details directly by email
This helps your sales or support team follow up quickly without needing to continuously check the Lead Report.
To configure this, go to Leads > Lead Settings.

Find and Claim an Existing WhatsApp Number#

We have introduced a simpler way to add an existing WhatsApp Business number to Platform when the number has already been set up with Meta.
You can now:
Enter your existing WhatsApp Business number and look it up
Select the number you want to add to Account
Verify ownership using a WABA ID, Business ID, or Phone ID
Add the number without repeating the complete WhatsApp onboarding flow
This is useful when your WhatsApp Business setup is already complete in Meta, but the number has not yet been added to your account.
To use this option, go to WhatsApp API > I already have connected WhatsApp number.

04 August 2026#

Module Settings#

We have introduced Module Settings to give you control over enabling and disabling system features across your project.
You can now:
Turn modules on or off based on your business requirements
Enable or disable marketing tools such as Contact & Broadcast and WhatsApp Inbox
Enable or disable technical modules like API Playground, Webhook, and Activity Log
Manage core product activations for WhatsApp API and AI Agent
Apply changes immediately for all team members in the project
This helps you keep your workspace organized and ensure team members only access active features.
To configure this, open WhatsApp API or AI Agent, go to Account > Module Settings.

Direct Excel & Media Upload for Campaigns#

We have introduced Direct Excel Upload and Direct Media Upload to make sending broadcast campaigns faster and simpler.
You can now:
Upload Excel (.xlsx) or CSV files directly at the time of sending a campaign without pre-importing contacts
Upload media files directly to generate public Media Id for campaign template headers
Support media uploads with optimized size limits:
Image: up to 5 MB (.jpeg, .png)
Video: up to 16 MB (.mp4, .3gpp)
PDF / Document: up to 100 MB (.pdf, .txt, .doc, .docx, .xls, .xlsx, .ppt, .pptx)
Easily switch between direct media upload and pasting a public URL
This streamlines the campaign launch workflow and eliminates the need for separate media hosting or pre-creating contact lists.
To use this feature, go to WhatsApp API, open Campaigns, click New Campaign, select Upload File under Target Audience, or use the file uploader under Template Mapping.

Welcome Banner#

We have introduced Welcome Banner under AI Agents to showcase interactive banners, grid layouts, and visual cards before visitors start a chat.
You can now:
Enable and configure a customized Welcome Banner for your AI chatbot
Choose layout styles including scrollable carousels and grid displays
Add custom cards with images, titles, and descriptions to highlight products or features
Add action buttons to cards for Send Message or Open URL
Guide chat visitors with key highlights and interactive entry points
This enhances visitor engagement and provides a visually appealing welcome experience on your chat widget.
To configure this, open your agent in AI Agents > Advanced Settings > Appearance > Welcome Banner.

VAPT Secured & Security Enhancements#

We are proud to announce that the product is now fully VAPT (Vulnerability Assessment and Penetration Testing) Secured.
With this security milestone, we have implemented comprehensive enterprise-grade security controls and hardened our application and API infrastructure against security vulnerabilities.
Key security highlights:
Completed comprehensive Vulnerability Assessment & Penetration Testing (VAPT) auditing
Advanced input validation and HTML injection / XSS sanitization across all forms and agent prompts
Strict API request body validation, CORS domain verification, and JWT revocation on logout
Hardened security headers including Content-Security-Policy (CSP) and X-Frame-Options for clickjacking defense
End-to-end data security and secure media upload pipelines
This milestone ensures maximum data privacy, robust compliance, and enterprise-grade security for your customer communication platform.
