Connect your AI Expert to WeChat, allowing users to chat with your Expert through a WeChat Official Account or Service Account. The WeChat channel targets consumer-facing users and is ideal for scenarios where you need to reach end users through WeChat.

​
Use Cases

The WeChat channel is particularly suited for:
  • Customer Support: Users receive AI-powered support through your Official Account
  • Knowledge Consultation: Followers can ask questions anytime and get professional answers
  • Service Notifications: Combine with Official Account template messages for proactive outreach
The WeChat channel primarily targets consumer-facing users reached through Official Accounts. For internal enterprise collaboration, we recommend the WeCom channel instead.

​
Integration Method

The WeChat channel is integrated through a WeChat Official Account (Service Account):
1

Prepare Your Official Account

You need a verified WeChat Service Account (Subscription Accounts have limited API access). Log in to the WeChat Official Account Platform.
2

Enable Developer Mode

Go to “Settings & Development” → “Basic Configuration” and enable Developer Mode. Take note of the AppID and AppSecret.
3

Configure Server Settings

Under “Server Configuration”:
  • URL: Enter the message callback URL provided by Profy
  • Token: Define a custom verification token
  • EncodingAESKey: Generate randomly
  • Message Encryption: Select secure mode
4

Enter in Profy

Enter the AppID, AppSecret, Token, and EncodingAESKey in the Expert Studio channel configuration.
5

Enable and Test

After saving the configuration, follow your Official Account on WeChat and send a test message.

​
Message Format

The WeChat channel replies with text messages:
  • Expert replies are sent as plain text or rich media messages
  • Basic text formatting is supported
  • Tool call processes are transparent to users — they only see the final result
  • Long replies may be split into multiple messages
WeChat has a 5-second response timeout. If AI processing takes longer than 5 seconds, the system uses the Customer Service Message API to reply asynchronously — users will receive a push notification once processing is complete.

​
Feature Scope

​
Fully Supported

​
Web-Only (Not Available via IM)

The following features are only available on the Profy web interface:
  • Sandbox code execution and preview
  • File tree browsing
  • Website generation and preview panels
  • Multi-panel workspace layout
  • File upload and real-time collaborative editing
WeChat channel users must first register a Profy account on the web and link their WeChat to use Expert and enable billing. Unlinked users will receive a prompt to register.

​
User Identity Association

The WeChat channel requires linking WeChat users to Profy accounts:
If a user’s Profy account is already linked to their WeChat, the system automatically recognizes and associates them. Conversation credits are deducted from the user’s Profy account.
When an unlinked WeChat user sends a message, they receive a prompt with registration/linking instructions, including a registration link and step-by-step guide.

​
Important Notes

  • WeChat Official Account APIs require a verified Service Account
  • Subscription Accounts can be integrated but have limited proactive messaging capabilities
  • WeChat imposes message frequency limits — monitor API quotas in high-concurrency scenarios
  • Enabling Developer Mode disables native Official Account features like auto-replies

​
FAQ

  • Verify Developer Mode is enabled
  • Verify the server configuration has passed validation
  • Verify the credentials in Profy channel configuration are correct
  • Check if the async reply mode was triggered due to timeout
If WeChat message processing exceeds 5 seconds, replies are sent through the async path. Users may experience a wait of several seconds up to about ten seconds. This is related to AI model inference time and tool calls, and is expected behavior.
The user’s WeChat is not yet linked to a Profy account. Guide them to register on the Profy web interface and link their WeChat in account settings.
