Creating a bill returns code 1000 "Internal Error" with API v3

Creating a bill returns code 1000 "Internal Error" with API v3

Hi all, I'm creating a script who creates a new bill in the admin panel via API v3 and PHP 7 (  https://www.zoho.eu/books/api/v3/#Bills_Create_a_bill )

This is a testing array I'm sending to the API


  2. $data = array(
  3.     "vendor_id"     => ZOHO_VENDOR_ID ,
  4.     "bill_number"   => "1234" ,
  5.     "date"          => "2019-04-01" ,
  6.     "line_items"    => array( array(
  7.         "quantity"          => "1" ,
  8.         "name"              => "Testing Bill Name" ,
  9.         "rate"              => "1000" ,
  10.         "account_id"        => ZOHO_ACCOUNT_ID ,
  11.         "tax_name"          => "Zero VAT Rate [0%]" ,
  12.         "tax_percentage"    => 0
  13.     ) ) ,
  14.     "notes" => "notes123"
  15. );
  16. $curlData = "JSONString=" . urlencode( json_encode( $data ) ) . "";
  17. /* JSON GENERATED
  18. JSONString=%7B%22vendor_id%22%3A%22<ZOHO_VENDOR_ID>%22%2C%22bill_number%22%3A%221234%22%2C%22date%22%3A%222019-04-01%22%2C%22line_items%22%3A%5B%7B%22quantity%22%3A%221%22%2C%22name%22%3A%22Testing+Bill+Name%22%2C%22rate%22%3A%221000%22%2C%22account_id%22%3A%22<ZOHO_ACCOUNT_ID>%22%2C%22tax_name%22%3A%22Zero+VAT+Rate+%5B0%25%5D%22%2C%22tax_percentage%22%3A0%7D%5D%2C%22notes%22%3A%22notes123%22%7D
  19. */
  20. $ch = curl_init();
  21. curl_setopt( $ch , CURLOPT_URL ,"https://books.zoho.eu/api/v3/bills?organization_id=" . ZOHO_ORGANIZATION_ID );
  22. curl_setopt( $ch , CURLOPT_POST , true );
  23. curl_setopt( $ch , CURLOPT_HTTPHEADER , array(
  24.     'Authorization: Zoho-authtoken ' . $access_token,
  25.     'Content-Type: application/x-www-form-urlencoded;charset=UTF-8'
  26. ));
  27. curl_setopt( $ch , CURLOPT_POSTFIELDS , $curlData );
  28. curl_setopt( $ch , CURLOPT_RETURNTRANSFER , true );
  29. $server_output = curl_exec( $ch );
  30. $info = curl_getinfo( $ch );
  31. curl_close ( $ch );
  32. var_dump( $server_output );
But the response from the API is 
  1. '{"code":1000,"message":"Internal Error"}' (length=40)
I tried different edits with the $curlData variable:

1. urlencode + json_encode ( without JSON_PRETTY_PRINT )
  1. $curlData = array( "JSONString" => urlencode( json_encode( $data ) ) );
  2. // JSON GENERATED

Is there any error in my request or JSON encoding? Thank you for your replies.
