Changelog

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.

Failed Message Analytics (Now Live)#

We’ve introduced Failed Message Analytics to give you deeper insight into message delivery issues. You can now view:
Total count of failed messages
Detailed failure reasons for each failed status
This feature is now available in your SendZen Analytics dashboard.

08 December 2025#

1. Analytics#

We have added an Analytics section in the dashboard so you can quickly review key usage metrics and understand how your WhatsApp traffic is performing.

2. New Sandbox flow#

We redesigned the Sandbox onboarding flow for a smoother experience and faster time to send your first test message.

3. New WABA connect flow#

We introduced a new WhatsApp Business Account (WABA) connect flow that makes it easier to link your number and complete the production setup with fewer steps and clearer guidance.

4. Free plan availability update#

The Free plan is no longer available for new accounts from the following countries:
Indonesia
United States
Canada
Philippines
Vietnam
China
Colombia
Russia

20 November 2025#

1. Signup and Login with Google#

Signup and login with Google is now generally available.

19 November 2025#

1. Sandbox Testing#

Instantly test flows and features without adding a phone number or completing onboarding. Ideal for rapid experiments and prototyping. Combined with programming code, the sandbox makes it easy to integrate your product without adding your own number.

2. Partner API Availability#

The Partner APIs are now open for builders managing multiple clients or reselling services. You can automate onboarding, manage accounts, and operate everything from your own systems.

3. Incoming Messages Documentation#

A new, easy-to-follow incoming message guide is now live. It covers receiving messages, webhook handling, and testing inbound traffic within the Sandbox.

4. Activity Logs#

All message events are now fully traceable, giving you clear visibility into how your flows behave in real time. Login and navigate to "Activity Log" in side bar and you will see the logs with complete payload.
