I’m trying to use the SDK’s

OAuthAuthenticator

to authenticate with the PayPal API and am running into some trouble. The API expects a request for an access token that looks like this if using curl

curl -v <https://api-m.sandbox.paypal.com/v1/oauth2/token> \
  -H "Accept: application/json" \
  -H "Accept-Language: en_US" \
  -u "client_id:secret" \
  -d "grant_type=client_credentials"

How do I replicate that with the oauth authenticator class? I tried using the

client_id

and

client_secret

properties and also tried setting the client ID and secret in the

username

and

password

params in

oauth_request_body()

but both returned a forbidden error
