SpringBoot REST client is throwing error 403

Hi Team,

When I am trying to make a REST client to automate the login process, I am writing below method to call to get the request token.

import java.util.Arrays;

import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.web.client.RestTemplate;


public class TestClient {

static final String URL_PROPERTIES = "https://kite.trade/connect/login?v=3&api_key=XXXXXXX";
public static void main(String[] args) {
testClient("old");

}

public static void testClient(String userId) {
// HttpHeaders
HttpHeaders headers = new HttpHeaders();

headers.setAccept(Arrays.asList(new MediaType[] { MediaType.APPLICATION_XML }));
// Request to return XML format
headers.setContentType(MediaType.APPLICATION_XML);
// headers.set("my_other_key", "my_other_value");

// HttpEntity: To get result as Employee[].
HttpEntity entity = new HttpEntity(headers);

// RestTemplate
RestTemplate restTemplate = new RestTemplate();

// Send request with GET method, and Headers.
ResponseEntity response = restTemplate.exchange(URL_PROPERTIES, HttpMethod.GET, entity, String[].class);

HttpStatus statusCode = response.getStatusCode();
System.out.println("Response Satus Code: " + statusCode);

// Status Code: 200
if (statusCode == HttpStatus.OK) {
// Response Body Data
//String list = response.getBody();

response.getBody().toString();
}

}

}

But when I am running the programme I am getting below error.

15:08:02.223 [main] DEBUG org.springframework.web.client.RestTemplate - Created GET request for "https://kite.trade/connect/login?v=3&api_key=2hag9jvlagzb97ms"
15:08:02.237 [main] DEBUG org.springframework.web.client.RestTemplate - Setting request Accept header to [application/xml, text/xml, application/json, application/*+xml, application/*+json]

Exception in thread "main" org.springframework.web.client.HttpClientErrorException: 403 Forbidden

Can someone please help, do I need to have SSL certificate from Zerodha to https request?

@sujith, @sujit123 Can you please help ? is there any way to write the Java REST client to get the Request Token by passing the api_secret?

Do u have any REST client example to invoke?

sujith

It is mandatory by the exchange that a user has to log in manually at least once a day. We don't recommend automating login.

@sujith thanks for your response, yes I agree once in a day i need to do login but whenever I am trying to execute order program is throwing Invalid Token exception,

So as per my understanding below are the steps I need to follow.

Step 1: Login to https://kite.trade/connect/login?v=3&api_key=XXX and comple authentication process and acquire the request token and persist in DB or file or in memory.
Question: Can I use same saved request token and access_token which I got it after generateSession method invoke or Every time manually I need to copy paste above URL and get request token and manually follow the same steps?

Even if I need new request token all the time when I run my program can I use curl to invoke https://kite.trade/connect/login?v=3&api_key=XXX this url to get the request_token

I am sorry if I am trying to ask stupid question but my plan is to make full process automated except once login and get the request token and use the same token all trading day.

sujith

Once you get access token it is valid for one whole day.
