I am connecting two salesforce orgs with connected app, named credential and Auth Provider.

  1. I have created connected app in target sandbox.
  2. Created Auth Provider in source org by providing Consumer and secret key from above connected App.
  3. Updated connected app callback URL with the call back url from Auth provider.
  4. Created named credential from above Auth provider.

When trying to authorise I am getting following error "error=redirect_uri_mismatch&error_description=redirect_uri%20must%20match%20configuration". Can some one help me understand what I am doing wrong.

  • What token and auth URL are you providing in the Auth Provider? Can you also grab the query parameter that contains the redirect_uri and see if it is the same as what you provided? May 26, 2018 at 5:55

I had the same problem. I found that callback url in the connected app should be the same as you have in your redirect_uri. I tested it with a tool called postman, maybe that can help you as well.

    @user2945545 I looked for this too, but eventually found it: if you click the Auth Provider record, you'll find the Redirect URI there :) Mar 6, 2021 at 0:30

Check callback URL in salesforce and callback URL in postman are same.

  1. In my case callback url field some time not editable in postman so I copied callback url from postman and changed in salesforce, This work fine me,else un check check twice this section copy paste that link to salesforce callback This procedure work for me.
