I got an answer,
First of all, we need to generate the client_id access token and secret ,
curl -v https://api.sandbox.paypal.com/v1/oauth2/token \ -H "Accept: application/json" \ -H "Accept-Language: en_US" \ -u "client_id:secret" \ -d "grant_type=client_credentials"
After receiving the access token, I need to make another api call to get complete information about the transaction,
curl -v -X GET https://api.sandbox.paypal.com/v1/payments/payment/Payment-Id \ -H "Content-Type:application/json" \ -H "Authorization: Bearer Access-Token"
After that I will receive complete transaction information .
