Getting started with a WeChat Channel

WeChat channel enables communication with users of the WeChat ecosystem through the Conversation API.

Prerequisites

Before you can set up a WeChat channel on the Conversation API, you need to do the following:

General requirements

1. Sign up for the Sinch Customer Dashboard.
2. Get access to the Conversation API.
3. Create your app.
4. Create your access key. Any API calls you make will require authentication information provided by your access key.

Refer to the Conversation API Getting started section for more information on any of these steps.

WeChat requirements

There are a few types of WeChat accounts, including Work Accounts, Verified/Unverified Subscription Accounts, and Verified/Unverified Service Accounts. Only Verified Service Accounts have full API access, so you need a WeChat Verified Service Account to integrate your Conversation API app with WeChat.

Configuring the Conversation API and WeChat integration

Next, you must enable the WeChat integration for your Conversation API app.

Enabling the WeChat integration using the Sinch Customer Dashboard

1. Log in to the Sinch Customer Dashboard and navigate to your Conversation API app.
2. Select WeChat in the Set up channels section.
3. Open your WeChat Official Accounts Platform admin portal and navigate to the Basic configuration page. Copy the Developer ID and Developer Password and paste them into the appropriate fields in the Sinch Customer Dashboard.
4. Click Change Configuration on the WeChat Official Accounts Platform. Copy the Token and EncodingAESKey and paste them into the appropriate fields on the Sinch Customer Dashboard.

   Note

   You may have to create or generate your own Token and EncodingAESKey.
5. Click Save on the Sinch Customer Dashboard. Copy the Callbak URL from the Sinch Customer Dashboard and paste it into the URL field of your WeChat Official Accounts Platform.

   Note

   You must have at least one Conversation API webhook to trigger POST callbacks to the given URL. For more information on how to create a webhook using the Customer Dashboard, see How to add a webook to a Conversation API app.
6. Ensure that the Message Encryption Method is set to Security Mode on your WeChat Official Accounts Platform.
7. Click Submit on your WeChat Official Accounts Platform.

Enabling the WeChat integration using the Conversation API

If you decide to configure your app through API calls, follow these steps:

1. Update your Conversation API app with WeChat channel credentials as given in the example snippet below:
   Copy

   Copied

   {
     "channel_credentials": [
       {
         "channel": "WECHAT",
         "wechat_credentials": {
           "app_id": "{{WECHAT_APPID}}",
           "app_secret": "{{WECHAT_APPSECRET}}",
           "token": "{{WECHAT_TOKEN}}",
           "aes_key": "{{WECHAT_AESKEY}}"
         }
       }
     ]
   }

   You need to replace {{WECHAT_APPID}}, {{WECHAT_APPSECRET}}, {{WECHAT_TOKEN}} and {{WECHAT_AESKEY}} with the values from you WeChat Official Accounts Platform.
2. Set the callback URL for your WeChat channel to the URL of the Conversation API displayed in WeChat Official Accounts Platform. The format of callback URL is:
   Copy

   Copied

   https://wechat-adapter.{{REGION}}.conversation-api.prod.sinch.com/adapter/v1/{{CONVERSATION_APP_ID}}/callback

   Where {{REGION}} is either eu1 or us1, depending on the region of your app. Replace {{CONVERSATION_APP_ID}} with the ID of your Conversation API app.
