I have been using postman to explore a REST interface. When using Postman's code generation feature, regardless of which programming language I select, Postman will always add a postman-token attribute in the header. Why is it there?,In first image you can see how I am sending a json object as form data in #code# parameter In second image I am getting a response while decoding it in Laravel...,i have to run API files which i have created in Postman and imported to VS-Code .

See for example PHP Curl:

< ? php

$curl = curl_init();

curl_setopt_array($curl, array(CURLOPT_URL => "https://myURL.com,
   CURLOPT_RETURNTRANSFER => true,
   CURLOPT_ENCODING => "",
   CURLOPT_MAXREDIRS => 10,
   CURLOPT_TIMEOUT => 30,
   CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
   CURLOPT_CUSTOMREQUEST => "GET",
   CURLOPT_HTTPHEADER => array(
      "authorization: Basic abcdefghijklmnop",
      "cache-control: no-cache",
      "postman-token: wt53gwg-e9bb-645d-g53d-e42f8765aut0"
   ),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
   echo "cURL Error #:".$err;
} else {
   echo $response;
}

Specifying authorization details,In the request Headers, the Authorization header passes the API a Base64 encoded string representing your username and password values, appended to the text Basic as follows:,You can also select the box to Encode the parameters in the authorization header for your request.,When the required details are complete in the Authorization tab for your request, Postman will add them to the Headers.

Bearer <Your API key>

Most Web APIs (if not all) are protected with JSON Web Tokens (JWT). In ASP.NET Core, this is done by configuring our Web APIs with a "Bearer" authentication scheme. When our APIs are decorated with the [Authorize] attribute, the requesting clients should provide the access token generated from the Authorization Server and pass it as a Bearer Authorization Header before clients can be granted access to our API endpoints.  ,As you can see, after configuring the bearer token as the Authorization header, the data is now returned for /weatherforecastrequest with status 200 Ok.,The preceding code initializes the tokenCreatedAt variable with the previous day. This is to ensure that we issue a request for getting a new access token on the first run.  Same goes for the handling the tokenExpiresIn value:,The following is the sample ressponse after requesting an access token from the Authorization Server in Postman:

Now, switch to the "Pre-request Script" tab in the collection and copy the following scripts:

var tokenCreatedAt = pm.collectionVariables.get("WeatherApi_Token_CreatedAt");

if (!tokenCreatedAt) {
   tokenCreatedAt = new Date(new Date().setDate(new Date().getDate() - 1))
}

var tokenExpiresIn = pm.collectionVariables.get("WeatherApi_Token_ExpiresIn");

if (!tokenExpiresIn) {
   tokenExpiresIn = 5000;
}

var tokenCreatedTime = (new Date() - Date.parse(tokenCreatedAt))

if (tokenCreatedTime >= tokenExpiresIn) {

   console.log("The token has expired. Attempting to request a new token.");

   pm.sendRequest({
      url: pm.variables.get("WeatherApi_AuthorityUrl"),
      method: 'POST',
      header: {
         'Accept': 'application/json',
         'Content-Type': 'application/x-www-form-urlencoded'
      },
      body: {
         mode: 'urlencoded',
         urlencoded: [{
               key: "client_id",
               value: pm.collectionVariables.get("WeatherApi_ClientId"),
               disabled: false
            },
            {
               key: "client_secret",
               value: pm.collectionVariables.get("WeatherApi_ClientSecret"),
               disabled: false
            },
            {
               key: "scope",
               value: pm.collectionVariables.get("WeatherApi_Scope"),
               disabled: false
            },
            {
               key: "grant_type",
               value: "client_credentials",
               disabled: false
            }
         ]
      }
   }, function(error, response) {
      console.log(response.json().access_token);

      pm.collectionVariables.set("WeatherApi_Token_CreatedAt", new Date());
      pm.collectionVariables.set("WeatherApi_Jwt", response.json().access_token);

      var expiresIn = response.json().expires_in;

      if (expiresIn) {
         tokenExpiresIn = expiresIn * 1000;
      }

      pm.collectionVariables.set("WeatherApi_Token_ExpiresIn", tokenExpiresIn);
   });
