Here is how you can do this - 
  1. Create a separate class that will hold the User Information like as shown below -  
    public class UserInformation {
    public String Name;
    public String UserCode;
    public Boolean UserState;
    public Boolean AllowApiLogin;
    public Boolean ShowHeaderToolTip;
    public String CurrencyId;
    public String LanguageId;
    public String UnitDistanceId;
    public String UnitPressureId;
    public String UnitTemperatureId;
    public String UnitTreadDepthId;
    public String RoleId;
    public String ContactEmail;
}
  2. Then create an another Apex Class called API which will have a method that will call the API Endpoint as shown below -  
    public class API {
    private static UserInformation generateUserInfo() {
        UserInformation usrInfo = new UserInformation();
        usrInfo.Name                = 'USER_1314';
        usrInfo.UserCode            = 'USER_1314';
        usrInfo.UserState           = TRUE;
        usrInfo.AllowApiLogin       = TRUE;
        usrInfo.ShowHeaderToolTip   = TRUE;
        usrInfo.CurrencyId          = 'e708dffd-ce3a-4c4e-a98a-48b67824c7f7';
        usrInfo.LanguageId          = 'f57a2f60-233d-400f-9607-33c55bdff4fc';
        usrInfo.UnitDistanceId      = '30857154-f8e4-4e7b-86b5-ad9b5cd05835';
        usrInfo.UnitPressureId      = '1115140c-ddf9-4cfb-af4c-38fd21ddadc2';
        usrInfo.UnitTemperatureId   = 'a61cfca0-ea07-49b4-a937-11c58b7cb24a';
        usrInfo.UnitTreadDepthId    = 'b71e84a0-8702-4e3e-a421-daa9051f0d0c';
        usrInfo.RoleId              = '1a0b66be-ff35-4ca4-931f-00003985e261';
        usrInfo.ContactEmail        = 'test@test_zoom.com';
        
        return usrInfo;
    }
    
    public static void createUser( String token ) {
        Http http = new Http();
        HttpRequest httpReq = new  HttpRequest();
        
        httpReq.setEndpoint( 'https://abcdef.com/api/tcUser' );
        httpReq.setMethod( 'POST' );
        httpReq.setHeader( 'Content-Type', 'application/json' );
        httpReq.setHeader( 'Accept', 'application/json' );
        httpReq.setHeader( 'Authorization', 'Bearer ' + token );
        
        String body = JSON.serialize( generateUserInfo() );
        
        httpReq.setBody( body );
        
        HttpResponse httpRes = http.send( httpReq );
    }
}
    I hope this makes sense. Let me know if you have any other doubts.

Hi Shruti 

Can you please suggest me a way to hold the token for few days.
As I have two API's to call.
First one returns the token and the another one created the User (for creating user, valid token in mandatory)

The token returned in the first API is valid for 11 days. Therefore, if I can check it expiry date before calling everytime.
Where can I store this token for say 11 days and then if the token is expired then call for the new one...
(do I have to create a new object to told this token, is this the only approach, please suggest.)

Thanks in advance
