title: salesforce oauth authorization
body: <p>I am trying to access my Salesforce account from my web service. </p>
  
  <p>In application settings I have added right callback URI.
  I am going to: <a href="https://login.salesforce.com/services/oauth2/authorize?client_id=3MVG9HxRZv05HarRSLB9DXXecYwIjvp5bTXOSgJDeX7rfqxNj1AshD3hy.OksG0ozEVmNEKrbchW21qna0dmC&amp;response_type=code&amp;scope=full&amp;redirect_uri=https%3A%2F%2Fmy.callback.uri&amp;state=udhdHud537hdHjsv4h" rel="nofollow noreferrer">https://login.salesforce.com/services/oauth2/authorize?client_id=3MVG9HxRZv05HarRSLB9DXXecYwIjvp5bTXOSgJDeX7rfqxNj1AshD3hy.OksG0ozEVmNEKrbchW21qna0dmC&amp;response_type=code&amp;scope=full&amp;redirect_uri=https%3A%2F%2Fmy.callback.uri&amp;state=udhdHud537hdHjsv4h</a></p>
  
  <p>But I am receiving: <code>error=redirect_uri_mismatch&amp;error_description=redirect_uri%20must%20match%20configuration</code></p>
  
  <p>What's wrong with the configuration?</p>
