OAuth 2.0 Username-Password Flow Problem - unsupported_grant_type
I am trying to implement OAuth 2.0 Username-Password Flow and below is my code and debug log - any help is appreciated. [https://help.salesforce.com/help/doc/en/remoteaccess_oauth_username_password_flow.htm]
Http httpProtocol = new Http(); HttpRequest request = new HttpRequest(); request.setHeader('Content-Type', 'application/json;'); request.setEndPoint('https://test.salesforce.com/services/oauth2/token'); request.setMethod('POST'); String strbody = '{"grant_type":"Password", "password":"MY PASSWORD + TOKEN", "username":"SANDBOX USER NAME", "client_secret":"secret", "client_id":"Client id from remote setttings"}'; request.setBody(strbody); HttpResponse response = httpProtocol.send(request); String jsonInput = response.getBody(); system.debug('jsonInput===>'+jsonInput);
Debug log -
