How to send an invoice by email with API ?

How to send an invoice by email with API ?

Hello, 

I'm trying to send an invoice by email with the API but I always get this error :

{
"code": 57,
"message": "You are not authorized to perform this operation"
}

This is my request : 


I use a header with a Oauth Token generated with the scope ZohoBooks.fullaccess.all and the body contains the contact_id of the contact used to create the invoice. 

What am I doing wrong ? What is the missing authorization ? 

Thank you for you help, 

Brenda
