Zalo Official Account (OA) is a verified business account on the Zalo platform that enables businesses to communicate with customers professionally.

It offers advanced features like automated messaging, broadcasts, analytics, and integration capabilities that aren’t available with personal accounts. Zalo OAs are specifically designed for business communication, marketing, and customer service.

For more information, visit the  https://oa.zalo.me/home

To connect your Zalo OA with third-party platforms:
– Register your app on Zalo Developer Portal
– Obtain API credentials (App ID and Secret Key)
– Generate access tokens
– Use these credentials to establish the connection

Most integrations use OAuth 2.0 authentication flow and RESTful API calls to exchange data between systems.

If you prefer a more streamlined approach, you can use HexaSync App to connect your Zalo OA with various third-party platforms without extensive technical knowledge.

HexaSync handles the technical aspects of API integration, token management, and data synchronization, making it accessible for businesses without dedicated development resources.

For more information on integration options, visit the HexaSync documentation.

– CRM platforms (like Salesforce, HubSpot)
– E-commerce platforms (like Shopify, WooCommerce)
– Customer support tools (like Zendesk, Freshchat)
– Marketing automation tools
– Chatbot platforms
– Custom business systems
Any system that can make HTTP requests to APIs can potentially integrate with Zalo OA.

Yes, most Zalo OA integrations require developer expertise. The integration involves working with APIs, handling authentication, managing webhooks, and writing code to process data between systems. For businesses without technical resources, some pre-built integration solutions exist, or you might consider hiring a developer familiar with Zalo’s API documentation.

Benefits include:
– Unified customer communication
– Automatic data synchronization
– Improved response times
– Consistent customer history across platforms
– Elimination of manual data entry
– Reduced switching between applications
– More personalized customer service

– Redirect users to Zalo’s authorization URL
– Receive the authorization code
– Exchange it for an access token using your app’s credentials

For OA integration specifically, you’ll need to request appropriate OA scopes during authorization.

Yes, automating replies from Zalo OA through integration is possible and is one of its key features. You can:
– Set up automated responses based on keywords
– Create decision trees for conversational flows
– Schedule messages
– Implement chatbots
The Zalo API allows you to programmatically send messages in response to user inquiries or triggered events in your system.

Yes, Zalo OA can be integrated with chatbots and AI assistants. You can use Zalo’s messaging APIs to connect your AI solution, allowing the chatbot to respond to user messages through your Zalo OA. The integration typically involves:
– Setting up webhooks to receive incoming messages
– Processing them with your AI engine
– Sending responses back via the Zalo API

Zalo provides several APIs for OA integration:
– Official Account API (for sending messages, managing followers)
– User API (for user profile information)
– Article API (for content management)

– Social API (for social interactions)

They also offer webhook capabilities for receiving real-time events and OAuth APIs for authentication.
For complete documentation, visit Zalo API Documentation.

To send messages from your system to users via Zalo OA:
– Obtain a valid access token
– Make a POST request to the appropriate endpoint (like /message/cs)
– Include parameters such as: Recipient’s user ID

– Content

The API supports various message formats including text, images, links, and interactive templates.
For detailed implementation guidance, refer to the Zalo Message API Documentation.

Yes, you can receive user messages from Zalo OA in helpdesk systems like Freshchat or Zendesk. This requires:
– Setting up webhooks in your Zalo Developer Portal
– Configuring forwarding of incoming messages to your helpdesk system’s API

For implementation details, visit Zalo Webhook Documentation.

Zalo OA integration uses robust security measures:
– OAuth 2.0 authentication protocol
– HTTPS-secured communications
– Limited-lifespan access tokens with defined scopes
– Signature verification for webhook payloads
– App verification requirements for public apps

To maintain security:
– Store tokens securely
– Handle refresh tokens carefully
– Conduct regular security audits

To test your Zalo OA integration before going live:
– Create a test OA account in the Zalo Developer Portal
– Use the sandbox environment to simulate user interactions
– Test API calls with tools like Postman
– Implement webhook testing with tools like ngrok
– Perform comprehensive testing covering normal operation and error handling
– Create test users to interact with your OA during development

Be aware of these limitations when integrating Zalo OA:
– Messaging limits (frequency caps and daily limits)
– User consent requirements (explicit opt-in needed)
– Message window restrictions (24-hour rule for proactive messaging)
– Content policy compliance
– Token expiration management
– Media file size and format restrictions
– Template message structure limitations

To handle expired tokens in Zalo OA integration:
– Implement token refresh logic that detects expiration errors (typically 401 responses)
– Use the refresh token to obtain a new access token
– Update stored credentials
– Retry the original request
– Include error handling for invalid refresh tokens
– Implement a fallback authentication flow if refresh fails
– Store token expiration times to proactively refresh before failure

Yes, you can integrate multiple Zalo OAs into a single system. This requires:
– Managing separate authentication credentials and tokens for each OA
– Implementing a database structure that associates messages with their respective OA
– Creating routing logic to direct incoming and outgoing messages to the appropriate OA
– Considering a middleware layer to standardize communication across all OAs

If you disconnect Zalo OA from your system:
– Real-time message delivery will stop
– Webhook events won’t be received
– Automated responses will cease functioning
– Users contacting your OA may experience delayed responses
– Access tokens will eventually expire
– Scheduled operations will fail
– Customer data synchronization will stop, potentially creating inconsistencies between platforms

You can track Zalo OA message delivery status by:
– Implementing webhook listeners for delivery events
– Storing message IDs returned by the API
– Updating message status based on webhook events

Zalo’s API returns immediate confirmation of message acceptance, while webhooks provide updates on actual delivery status. Some advanced metrics are also available through Zalo’s analytics dashboard.

Yes, Zalo OA supports webhook integration for real-time updates. You can:
– Register webhook URLs in the Zalo Developer Portal
– Receive instant notifications when users:
