How to make a GET request that takes oauth1 authentication

Question

I am trying to fetch some available slots for an appointment booking application using Axios and GET request in node.js.

i have tested the endpoint in postman and it works flawlessly, i copied the generated code for the request from postman, but it gives me a 401 Authentication error.

app.get("/slots", (req, res) => {
    getAvailableSlots(res);
})

const getAvailableSlots = (res) => {
    let config = {
      method: 'get',
      maxBodyLength: Infinity,
      url: '<url>&oauth_consumer_key=<key>&oauth_token=<token>&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1680087781&oauth_nonce=AKuBSQsiXz1&oauth_version=1.0&oauth_signature=nRiByohboigwEbDuqr0yDzy%2BHjw%3D',
      headers: { 
        'Cookie': 'session_id=fd65f21c120061ce905241be94d10f0fd807cf48'
      }
    };
    
    axios.request(config)
    .then((response) => {
      res.send(JSON.stringify(response.data));
    })
    .catch((error) => {
      res.send(error);
    });

}

this is the error that i got
