TASK : I want to send the recordId of the updated Opportunity record whenever it is updated. I want to send it to external web service , my code is working and fulfilling my requirement but have a look at it once. 

I first got the updated Opportunity recirdId from trigger then I called my first callout where I got the 'Token' , and then I called the secod method where I send the recordId.

Please examine this code. Thanks in advance 

public class OpportunityToBeSent {
    @future (callout=true)
    public static void makePostCallout(String recId) {
        String token; 
        //        System.debug('recorddIdd' + recorddIdd);
        Http http = new Http();
        HttpRequest request = new HttpRequest();
        
        request.setEndpoint('https://XXXXXXXXXXXXXXXXXXXX/authenticate');
        request.setMethod('POST');
        request.setHeader('Content-Type', 'application/json;charset=UTF-8');
        // Set the body as a JSON object
        request.setBody('{"email": "XXXXX@XXXX.com","password": "XXXXXX"}');
        System.debug('request'+ request);
        HttpResponse response = http.send(request);
        System.debug('response'+ response);
        // Parse the JSON response
        if (response.getStatusCode() != 200) {
            System.debug('The status code returned was not expected: ' +
                         response.getStatusCode() + ' ' + response.getStatus());
        } else {
            System.debug(response.getBody());
            Map<String, Object> results = (Map<String, Object>) JSON.deserializeUntyped(response.getBody());
            Map<String, Object> m2 = (Map<String, Object>) results.get('data');
            System.debug('results'+ m2.get('jwtToken'));
            token = (string)m2.get('jwtToken');
            System.debug('token '+ token);
        }
        makePostCalloutt(recId , token);
        
    }
    
    
    public static void makePostCalloutt(String recId , String tokenn) {
        System.debug('Token >>>'+ tokenn);
      
        String body = recId;
        Http http = new Http();
        HttpRequest request = new HttpRequest();
        
        request.setEndpoint('https://XXXXXXXXXXXXXXXX?id='+ body);
        request.setMethod('POST');
        request.setHeader('Content-Type', 'text');
        request.setHeader( 'token', 'Bearer ' + tokenn );
        // Set the body as a JSON object
        request.setBody(body);
        System.debug('request'+ request);
        HttpResponse response = http.send(request);
        System.debug('response'+ response);
        // Parse the JSON response
        if (response.getStatusCode() != 200) {
            System.debug('The status code returned was not expected: ' +
                         response.getStatusCode() + ' ' + response.getStatus());
        } else {
            System.debug(response.getBody());
        }
        
    }
