Is there a way to retrieve refresh_token via https://test.salesforce.com/services/oauth2/token REST API call?
I've seen it's possible via connected app but we want to retrieve the refresh token via standard user/password login:
{
"grant_type":"password",
"username":"username",
"password":"userpassword",
"client_id":[CLIENT_ID],
"client_secret":[CLIENT_SECRET],
"format":"json"
}
Is this possible?
