step 1 : Fetching access_token by URL

https://accounts.zoho.com/oauth/v2/token

with payload includes scope = " Aaaserver.profile.READ"

and getting access_token successfully

{ "access_token": "xxxx.xxxxxxxxxd57cxxx9xxxd1xxxexxxxxx.8242xxx4357xxxc6bxxx85xxxb6xxxxx", "expires_in_sec": 3600, "api_domain": "https://www.zohoapis.com", "token_type": "Bearer", "expires_in": 3600000 }

step 2: But while trying to read User Info with same access_token receiving error as below

url : https://accounts.zoho.com/oauth/user/info

header :  Authorization = Zoho-oauthtoken xxxx.xxxxxxxxxd57cxxx9xxxd1xxxexxxxxx.8242xxx4357xxxc6bxxx85xxxb6xxxxx

Response

{

    "response": "error",

    "cause": "INVALID_OAUTHSCOPE"

}  

Also tried with scope =  ZohoMail.folders.READ,  scope =  Aaaserver.profile.read, scope = a aaserver.profile.read

so i need to know what is right option for scope ?????
