The redirect_uri issue in LinkedIn Login using React

Question

I am trying to add LinkedIn authentication with React following this link https://github.com/orionsoft/react-linkedin-login. The tutorial doesn't mention the redirect_uri due to which I have left it as blank. But when I try to log in using my react app, an error occurs What is the correct redirect_uri to use in react application. The LinkedIn error goes like this "The redirect_uri does not match the registered value".

My website URL is http://localhost:3000

Please refer the screenshots for the settings of LinkedIn Developer Console

I am adding the code in react

import React, { Component } from 'react';
import LinkedIn from 'react-linkedin-login'

class SocialLogin extends Component {
  constructor(props)
  {
    super(props);
  }
  
  callbackLinkedIn ({code, redirectUri}) {
    console.log(code+"linked in code")
  }

  
  render() {
    return (
      <div className="login-box">
        <div className="social-login">
             <LinkedIn
              clientId='***********'
              callback={this.callbackLinkedIn.bind(this)}
              text='LinkedIn' /> 
        </div>
      </div>
    );
  }
}

export default SocialLogin;

I am getting this issue ""The redirect_uri does not match the registered value"".please refer the last image

I have given the 4 redirect URLs like:

1. http://localhost:3000
2. http://localhost:3000/callback
3. http://localhost:3000/signin-linkedin
4. http://localhost:3000/auth/linkedin/callback

But I am getting the same issue. Please help me out with this issue.

Answer 1

Seeing your redirect URL in the screenshot, it can be deciphered that: redirect_uri = http%3A%2F%2Flocalhost%3A3000%2F which translates to http://localhost:3000/.

You are missing a / in the end. Your currently added URLs are all unnecessary.

Answer 2

You need to add the "http://localhost:3000/" in Authorized URI section. The request sent to Linkedin with the trailing slash at the end as parameter for redirect_uri.
