WeChat public platform development customer service interface to send customer service messages

When the user actively sends a message to the official account (including sending information, clicking the custom menu clike event, subscribing event, scanning QR code event, payment success event, user rights protection), WeChat will push the message data to Developers, developers can call the customer service message interface within a period of time (currently 24 hours) and send messages to ordinary users by POSTing a JSON data packet. There is no limit on the number of sending times within 24 hours. This interface is mainly used for functions such as customer service that require manual message processing, so that developers can provide users with better services.

1. Get ACCESS_TOKEN

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

Under normal circumstances, WeChat will return the following JSON data packet to the public account:
{"access_token":"ACCESS_TOKEN","expires_in":7200}

2. Send a message

Send a text message

Send a picture (media_id needs to be uploaded first Picture obtained)

    "touser":"oLVPpjqs9BhvzwPj5A-vTYAX3GLc",

    "image":
    {
      "media_id":"jViS8sQUXIh6rTdkz2qUOD5pvChYpp50i9rsLR4YnCm-pqdpiHhz6xbN2KAboScV"
