Capturing Conversation

WeChat has two features to get your customers to follow your account and start a conversation:

QR Codes

QR codes can be displayed in physical stores and websites or used in emails you send customers to encourage them to scan it on their WeChat mobile application to follow you and initiate a conversation. Learn how to generate a QR Code here.

In-app Searches

WeChat has a powerful search engine that allows users to search your official account in-app by the display name and keywords in your description. Users can easily follow you and start a conversation. Learn more about WeChat In-app search here.

Messaging Limits

WeChat has limited the amount of time businesses can chat with Contacts to prevent spamming. WeChat Official Accounts have a messaging window of 48 hours to reply to a Contact. Due to the channel’s limitation, businesses can only send up to 20 messages within this 48 hours session.

The messaging window will close if 48 hours have passed or the business has reached the 20 messages limit since the last incoming message from Contact.

If the Contact responds to your message, both the messaging window and message limit will be reset.

If you exceed the 20 messages limit or once the 48-hour session expires, a red exclamation mark appears next to the message sent on the platform, indicating the message is not delivered.

You won’t be able to send messages after the session expires unless the Contact reopens the messaging window with a new message.
