Been at this for days now and cannot seem to resolve this error. I am trying to implement the Log in with PayPal initially in Sandbox, and running on my local machine (WAMP). When I click the login button I get the error : This action isn't supported. Please return and report this error so that we can support it in the future. (invalid client_ID or redirect_uri) I am using PHP, JAVA under WAMP The login button is : <span id='lippButton'></span> <script src='https://www.paypalobjects.com/js/external/api.js'></script> <script> paypal.use( ['login'], function (login) { login.render ({ "appid":"<clientid>", "authend":"sandbox", "scopes":"openid Full name Email address", "containerid":"lippButton", "responseType":"code", "locale":"en-us", "buttonType":"LWP", "buttonShape":"pill", "buttonSize":"lg", "fullPage":"true", "returnurl":"http://localhost.<mysite>:8080/account.php" }); }); </script>
