var url = "https://slack.com/api/chat.postMessage";
var auth_token = auth_token; //Your Bot's auth token
var headers = {
   "Authorization": "Bearer " + auth_token,
   "Content-Type" : "application/json"
}
var body = {
    channel: userSlackId, // Slack user or channel, where you want to send the message
    text: "Your text goes here."
}
request.post({
   "url": url,
   "headers": headers,
   "body": JSON.stringify(body)
}, (err, response, body) => {
   if (err) {
       reject(err);
   }
   console.log("response: ", JSON.stringify(response));
   console.log("body: ",body);
});

You have to set headers as Authorization, and add Bearer before your token as it is mentioned in slack docs. Also, send user/channel in body. Here I'm providing the link for the same for your reference https://api.slack.com/methods/chat.postMessage#channels . Hope this helps.

Not sure which language you're using, but if using Postman to test, you can try the following format.

raw Postman request

POST /api/chat.postMessage HTTP/1.1
Host: slack.com
Content-Type: application/json
Cache-Control: no-cache

{
    "text": "This is a line of text.\nAnd this is another one.",
    "token": "XXXX",
    "channel": "XXXX",
}

Add your parameters to the end of Slack's chat.postMessage endpoint like this:

http://slack.com/api/chat.postMessage?token=XXX&channel=XXX&text=XXX

Then make a GET request to that URL to post your message. Personally I'd suggest doing this as a Node application and using the request package obtained via npm. Makes it very easy.

Post message to Slack in a Node App

  1. Create a new node project and then change to that folder on the command line

  2. On the command line type npm install -g request to install the request module for your project

  3. Inside the index.js file (or wherever you plan on calling the API) do as follows:

    //Import request module
var request = require('request');

//Replace your token, channelID and text here
var path_to_call = 'http://slack.com/api/chat.postMessage?token=XXX&channel=XXX&text=XXX';

request(path_to_call, function(error, response, body) {
     if (!error && response.statusCode == 200) { 
         console.log('Success');
     } else { 
         console.log(error);
     }
});

If you just want to post messages I would recommend to use an Incoming Webhook. They are specifically designed for that purpose and easier to use than API calls.

An Incoming webhook is a custom URL that you can create for your Slack team and then use to send messages into any channel. For sending a message you only need to submit your message in JSON format along with some parameters as POST request to your webhook URL.

If you are using PHP scripting on your website then you best use CURL for the call.

Check out the documentation for details on how to use it.
