Hi,

We are trying to use the POST /api/v3/estimates endpoint but we always end up with a 400 Bad Request : {"code":2,"message":"The request passed is not valid."}.

Bellow is the curl request used (with credentials masked and customer_id changed):

curl 'https://invoice.zoho.com/api/v3/estimates?authtoken=********************************&organization_id=********' -X POST -d 'JSONString={
  "customer_id": 982000000561057,
  "date": "2017-08-31",
  "line_items": [
    {
      "name": "Name",
      "description": "Description",
      "quantity": 1,
      "rate": 555.43,
      "item_total": 555.43,
      "tax_percentage": 20,
      "tax_name": "TVA"
    }
  ]
}'

Are we missing some required fields or something ? We couldn't find that information in the docs.
