Send Email API

Send Email API

Hi,

I'm trying to test the Send Email API using Postman.

The URL is 
http://mail.zoho.com/api/accounts/<my_account_ID>/messages

Header Info
Authorization: <my authorization token>

Body - Raw(JSON)

{
    "fromAddress": "my email address",
    "toAddress": "my gmail address",
    "subject": "Email - Always and Forever",
    "content": "Email can never be dead. The most neutral and effective way, that can be used for one to many and two way communication."

}

Yet I get the following error:
{"data":{"errorCode":"INVALID_METHOD"},"status":{"code":404,"description":"Invalid Input"}}

So firstly, where do I get the account ID? I am using the one that says "User ID" when I select my Profile on the top right corner of my mail window.

2. The Authorization header: Should it be only the token or instead the complete string prepended to the token (as described in  https://www.zoho.com/mail/help/api/authtoken.html)    Zoho-authtoken <AuthToken-Value> ?

Thanks,
Deepak
