With the widespread use of WeChat, Enterprise WeChat has become an essential tool for many businesses to facilitate internal communication and information transmission. The message push feature in Enterprise WeChat enables timely delivery of important information, improving work efficiency. This article will guide you through developing a message push API with PHP to quickly implement this functionality.
First, you need to register a developer account in Enterprise WeChat and create an application in the management console to obtain the necessary application credentials. Log in to the Enterprise WeChat management console, navigate to “Applications and Mini Programs” > “Applications,” then click “Create Application.” Follow the prompts to enter the application name and visibility scope. Once created, you will get the CorpID, AgentID, and Secret—essential parameters for subsequent API calls.
Obtaining an access_token is a crucial step to calling Enterprise WeChat APIs. The access_token acts as an authorization token and must be included in every API request.
API endpoint example:
https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=YOUR_CORPID&corpsecret=YOUR_SECRET
Here, YOUR_CORPID and YOUR_SECRET correspond to the CorpID and Secret obtained when creating the application. You can use PHP’s curl functions to send an HTTP request to retrieve the access_token. It’s recommended to cache the access_token, such as saving it to a file or database, to avoid frequent requests.
After obtaining the access_token, you can use the message sending API to push messages. The API supports multiple message types, including text, images, voice, video, and files.
Message sending API example:
https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=YOUR_ACCESS_TOKEN
Request parameters include CorpID, AgentID, message type, and message content. Use PHP’s curl functions to send an HTTP POST request with parameters in JSON format. The API response includes error codes and messages for you to handle accordingly.
Security is critical when developing the Enterprise WeChat message push PHP API. Ensure that only legitimate requests can access the API and prevent abuse.
Implement signature verification by generating a signature based on request parameters and the Secret using the SDK provided by Enterprise WeChat. Send the signature with the request so the API can verify its validity, ensuring requests are from authorized sources.
You can also restrict access by whitelisting IP addresses or domains, and validate requests based on IP or Referer headers to filter unauthorized access effectively.
In summary, by registering a developer account, obtaining the access_token, calling the message sending API, and enforcing security measures, you can develop a robust Enterprise WeChat message push API with PHP. Enterprises can customize and extend functionality based on their business needs to build efficient communication solutions.
