II did everything, did double check, but when I submit to verify, the chalenge is wrong: "Challenge Not yet complete... here's what's wrong: 
The initial submission action is not correct for the 'Discount Approval Process'. VP approval does not appear to be required for discounts over 40% for step #2 in the process."

But it's correct, as you can see in diagram:

Is there any way to cutomize classic visualforce page to look like lightning VF page (without to switching to lightning)? 

My requirement is to build a new VF page that is about to be used in salesforce classic but the styling should be like lightning.

 

I use the password flow to get the access token like this:

 

curl -k https://login.salesforce.com/services/oauth2/token -d "grant_type=password" -d "client_id=[clientid]" -d "client_secret=[clientsecret]" -d "username=[myusername]" -d "password=[mypassword][mysecuritytoken]"

 

which returns

 

{"id":"https://login.salesforce.com/id/00Di0000000JgfhEAC/005i0000000dbdwAAA",
"issued_at":"1366942091291",
"instance_url":"https://na15.salesforce.com",
"signature":"yZsqE5VvYAZb+2dVw2zUNFsTllZxy9JjZBMFxYIGcAI=",
"access_token":"00D...vZ1"}

 

Then I do

 

curl -k https://na15.salesforce.com/services/data/v27.0/chatter/users/me -H 'Authorization: Bearer 00D...vZ1'

 

but I get this error response:

 

[{"message":"Session expired or invalid","errorCode":"INVALID_SESSION_ID"}]

curl: (6) Could not resolve host: Bearer
curl: (6) Could not resolve host: 00D...vZ1'

 

Any idea of what is wrong?
