Automatically obtain OAuth 2.0 Token

🙋 Help

Hi All,

I am trying to get an OAuth 2.0 access token by authorizing using browser. However, it needs manual intervention to click “Get New Access Token.” Is there a way to automate this in the pre-requisite script? I have this snippet, but now sure how to mention “Authorize using browser” and “Get New Access Token”.

const tokenUrl = ' ';
const redirectUrl = ' ';

const clientId = ' ';
const clientSecret = ' ';
const scope = ' ';
const audience = ' '

const getTokenRequest = {
  method: 'POST',
  url: tokenUrl,
  body: {
      mode: 'formdata',
      formdata: [
          { key: 'grant_type', value: 'authorization_code' },
          { key: 'redirect_uri', value: redirectUrl},
          { key: 'client_id', value: clientId },
          { key: 'client_secret', value: clientSecret },
          { key: 'scope', value: scope },
          { key: 'state', value: 'a_state' },
          { key: 'audience', value: audience }
      ]
  }
};

pm.sendRequest(getTokenRequest, (err, response) => {
const jsonResponse = response.json();
const newAccessToken = jsonResponse.access_token;

pm.variables.set(‘access_token’, newAccessToken);
});
