WeChat integration for business: how to connect (2026)

Want WeChat chats to reach your whole team instead of one person's phone? That is what a WeChat integration does.

It connects your WeChat Service Account to the tools your team already uses, so customers get answers and no chat sits on a single phone. This guide covers the account you need, the ways to connect, and the steps to link it to SleekFlow.

What is a WeChat integration?

A WeChat integration connects your WeChat Official Account to other business tools, such as a shared inbox or a CRM. Customer messages then reach your whole team instead of one phone. SleekFlow connects to verified Service Accounts, and its Help Center lists what works on WeChat and what does not.

Why use WeChat for business?

Tencent reported 1.439 billion combined monthly active users for Weixin and WeChat at 30 Jun 2026, up 2% on a year earlier. If your customers are in China, or are Chinese-speaking customers elsewhere, many of them already use it.

Connecting your account changes three things:

• One inbox for every agent. WeChat chats sit next to your other channels in SleekFlow's shared inbox, so nobody switches apps.

• Chats stay with the business. Conversation history lives in the shared inbox, not on one employee's phone.

• Replies stay inside the 48-hour limit. When the whole team can see a chat, fewer messages wait for one person to come online.

Which WeChat account do you need for integration?

You need a Service Account. It is the Official Account type for customer service and sales, and the only type SleekFlow connects to. Tencent offers overseas companies only that type, so most businesses outside mainland China have no other choice.

Our guide to WeChat Official Account features shows what each type unlocks.

What are the ways to integrate WeChat?

There are three ways to integrate WeChat: build on Tencent's API yourself, use a general automation tool, or use a messaging platform such as SleekFlow. The right one depends on how much engineering time you have and whether you need a shared inbox.

What can you do with WeChat in SleekFlow?

Once connected, WeChat conversations arrive in SleekFlow's shared inbox next to your other channels. SleekFlow's WeChat channel overview lists what you can send and the limits to plan around, so read it before you design replies.

• One Service Account. You can connect one Service Account to a SleekFlow account.

• Customer first. Businesses cannot start conversations, and you can send at most 5 messages within 48 hours of the customer's last message.

• Message types. You can send text, voice notes with a 16MB file limit, product messages, emojis and payment links (the payment feature must be on).

• Delivery ticks. One-to-one messages show a double tick once WeChat confirms delivery. Broadcasts show a single tick once sent, with no status for each recipient.

• No message fee. Sending and receiving WeChat messages in SleekFlow is free.

How do you integrate WeChat with your website?

To bring website visitors into WeChat, put your Service Account's QR code where customers already look, such as product pages, checkout, packaging and in-store displays. A scan lets the customer message you first, and a customer message is the only way a WeChat chat can start.

How do you connect WeChat to SleekFlow?

To connect WeChat to SleekFlow, you need a verified Service Account. Add SleekFlow's IP address for your data center to your WeChat IP whitelist, copy your App ID and App Secret, then add WeChat as a channel in SleekFlow.

Step 1. Get a verified Service Account

Register on the WeChat Official Accounts Platform and choose Service Account. Tencent's overseas verification FAQ lists a US$99 fee per application and 7 to 15 working days for review after you pay and submit complete documents.

Our WeChat Official Account setup guide walks through registration and verification.

Step 2. Whitelist the SleekFlow IP address

On WeChat's Basic Configuration page, add the SleekFlow IP address for your data center to the IP whitelist. The connection guide lists the address for each data center.

Step 3. Copy your App ID and App Secret

On the WeChat Developers Platform, open the Service account page and copy your App ID and App Secret.

Step 4. Add WeChat in SleekFlow

In SleekFlow, add WeChat as a channel and enter those details. Follow the connection guide for the exact steps.

The guide says the WeChat admin must have completed real-name verification. It also warns that your WeChat custom menu can become inaccessible on the platform after you connect, so finish the menu first.
