When i try to get access token by calling the below url from Chrome Rest Client


by passing all headers

grant_type: password
username: [email protected]
password: *****+SecurityToken
client_id: 3MVG9ZL0ppGP5UrAK9L_2UlHYwS_Zi1B_vyAIzVVE4jOdt4i.aJCYuioKS7VsCuokwWAm2uIZKSms
client_secret: 5435274860481357
Content-Type: application/x-www-form-urlencoded

In connected app i have given return url as http://localhost

But i am getting response as

{"error":"unsupported_grant_type","error_description":"grant type not supported"}

Is there a way to come out of this and call rest services using rest client
