The example in this article describes the solution to the failure to send messages after [Enterprise Official Account] is upgraded to [Enterprise WeChat]. I would like to share it with you for your reference. The details are as follows:

Recently, I saw news that WeChat upgraded corporate public accounts to corporate WeChat. I didn't care about it at the time, but later I discovered that the program that used the interface of the company's public account to send notification messages could no longer send messages.

So, I opened the upgrade message again and read it carefully: the enterprise account will be migrated to the enterprise WeChat management background (work.weixin.qq.com/login) for unified management. Previously, the management backend address of the company's public account was qy.weixin.qq.com. If I can't send messages, could it be that the interface address has also changed?

Log in to the new backend and check it out, and find that the Secret value of the application has changed, with fewer digits than before. After replacing the Secret value in the code with a new one, I found that it still didn't work. After debugging, I found an error when using

post request to call the interface to send a message: {"errcode":-1,"errmsg":"Invalid input"}. There may be two reasons for the analysis: the address of the message sending interface called is wrong; or the format of the post parameters passed is wrong.

Fortunately, I found the API documentation for Enterprise WeChat on its official website:

https://work.weixin.qq.com/api/doc, which has more detailed usage. illustrate. It was confirmed that the URL address of the calling interface has not changed (https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=ACCESS_TOKEN is still used to send messages). However, I found that the format of the text message is a little different. The official website example is as follows:

I should have passed the above UserID and PartyID as numerical values, but the example is If it is placed in quotation marks, it will be treated as

string. So, I changed the code to a string and tried it, and it worked. . .
