Hi guys, I have been trying to use your api services to add leads that would reflect on my CRM dashboard.

--I am doing a POST request on url - https://www.zohoaaapis.com/crm/v2/leads. I have also provided my access token under header for "Zoho-oauthtoken" but the response I receive is
{
"code": "AUTHENTICATION_FAILURE",
"details": {},
"message": "Authentication failed",
"status": "error"
}

--The request format was the one on the docs. This was it -
{
"data": [
{
"Company": "Zylker",
"Last_Name": "Daly",
"First_Name": "Paul",
"Email": "p.daly@zylker.com",
"State": "Texas"
},
{
"Company": "Villa Margarita",
"Last_Name": "Dolan",
"First_Name": "Brian",
"Email": "brian@villa.com",
"State": "Texas"
}
],
"trigger": [
"approval",
"workflow",
"blueprint"
]
}

Can anyone please let me know if there is something I missed. My registered email is sameeragarwal110@gmail.com.

Thanks in advance.
