How to quickly implement WeChat mini program customer service system with PHP

With the rapid development of WeChat mini programs, more and more companies have begun to deploy on the WeChat platform and use mini programs to achieve more business expansion and user services. In the process of mini program marketing, good customer service is a crucial part. How to quickly implement WeChat mini program customer service system has become a topic of concern to major enterprises and developers. In this article, we will introduce how to use PHP to implement the WeChat mini program customer service system, making the communication between your business and users easier and more efficient.

First of all, we need to know the basic process of the WeChat mini program customer service system. As shown in the figure below:

In the flow chart, we can see that the implementation of the customer service system is very similar to the implementation of the WeChat official account, except that the WeChat API needs to be called through the JS-SDK in the mini program. Data interaction.

Next, we will introduce in detail the solution of using PHP to implement the WeChat mini program customer service system. The specific steps are as follows:

1. Get the APPID and APPSECRET of the WeChat mini program

First, we need to apply for a mini program on the WeChat mini program platform and obtain the mini program's APPID and APPSECRET. After successful acquisition, we can use these two parameters to make API calls and generate AccessToken.

2. Get AccessToken

When calling WeChat’s API, we need to obtain an AccessToken to access the WeChat public platform interface. To obtain AccessToken, you need to send an HTTP request to the WeChat API server and carry the APPID and APPSECRET parameters. The API for obtaining Token is as follows:

https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=APPID&secret=APPSECRET

Among them, the APPID and APPSECRET parameters need to be replaced with the APPID and APPSECRET of the mini program you applied for. The JSON data obtained by sending a GET request will contain AccessToken, expires_in and other parameters. Among them, AccessToken is an important parameter for our subsequent calls to the WeChat API and needs to be kept properly.

3. Create customer service session

In the mini program, we need to create a new customer service session when the user clicks to enter the customer service page. The interface API is as follows:

https://api.weixin.qq.com/customservice/kfsession/create?access_token=ACCESS_TOKEN

Among them, ACCESS_TOKEN is the AccessToken we obtained before. After the creation is successful, we will get a session ID and save the ID.

4. Get the customer service session list

In the mini program customer service system, we need to get the customer service session list of the designated customer service so that we can handle customer inquiries in a timely manner. The interface API is as follows:

https://api.weixin.qq.com/customservice/kfsession/getsessionlist?access_token=ACCESS_TOKEN&kf_account=KF_ACCOUNT

Among them, ACCESS_TOKEN is the AccessToken obtained before, and KF_ACCOUNT needs to be replaced with the customer service account you created.

5. Send customer service messages

In the mini program, we can send multiple types of messages to users through the customer service session window, including text messages, picture messages, and audio messages , video messages, etc. The following are some common message sending APIs:

https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=ACCESS_TOKEN

Among them, ACCESS_TOKEN is also the AccessToken obtained previously. We need to carry the message content of the POST request and parameters such as the customer OpenID (user ID).

6. End customer service session

After the communication between customer service and the user ends, we need to end the customer service session. The interface API is as follows:

https://api.weixin.qq.com/customservice/kfsession/close?access_token=ACCESS_TOKEN

Among them, ACCESS_TOKEN is also the AccessToken obtained before. We need to carry the session ID of the POST request and the user OpenID and other parameters.

The above is the basic process of using PHP to implement the WeChat mini program customer service system. We need to provide users with a customer service window in the mini program, and use our own server's PHP code to interact with the WeChat API.

Different from the conventional PHP Mysql architecture, the WeChat applet customer service system needs to use technologies such as MYSQL Redis CURL to improve the system's concurrent processing capabilities and data reading and writing capabilities. In terms of data storage, we can use the MYSQL database to save user consultation records, and in the customer service system, we can use Redis to cache some key data, such as AccessToken, SessionID, etc.

Of course, we can also use some mature WeChat mini program customer service libraries for secondary development, such as Tencent Cloud's WeChat mini program customer service SDK, etc. By using the SDK, we can quickly build a complete WeChat mini program customer service system to improve the development efficiency and stability of the system.

To sum up, using PHP to quickly implement the WeChat mini program customer service system can provide enterprises and developers with an efficient, safe and stable customer service solution.
