Invalid redirect_uri. This value must matc

Answer 1

please check your redirect_url. for my case I see like this.

https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=77k93y0w31zaey&redirect_uri=http%3A%2F%2Flocalhost%3A1729%2Fsignin-linkedin&scope=r_basicprofile%2Cr_emailaddress&state=nhAC-nR-CgEwO3XS2ezANhuPBMz-IUmLPJYgGHlZvZ8B1pCfsGBU0PR0dZ5XxE4zbyeI0RLcKByqPLKkgQdqMm4s6DjFYqMCEehYA2iWT9MfioEHjPXGCt2USxUTF0wKBpflCUjG5URVlJa3qI7U3ydFOErZ4Hhnr9SVmKdf1bithYfbOqBx345o8LQLexbddQ687vP6y0szrIyCM6FHip1tCpOY3Hgg5FJQEFH1mCJ_yLunD5vDUN4VVfkQbcjk

for this I add the url for OAuth 2.0 Authorized Redirect URLs:

http://localhost:1729/signin-linkedin

where http://localhost:1729 =base url and
signin-linkedin = the string which add after base url
