Hello, I am trying to create a sales order from Zoho CRM
 and that this is automatically created in Zoho Inventory, 
I am using the following data:

00003\",\"date\":\"2015-05-28T00:00:00.000Z\",\"shipment_date\":\"2015-06-02T00:00:00.000Z\",\"custom_fields\":[{}],\"reference_number\":\"REF-S-00003\",\"line_items\":[{\"item_id\":4815000000044100,\"line_item_id\":4815000000044897,\"name\":\"Laptop-white\/15inch\/dell\",\"description\":\"Just a sample description.\",\"item_order\":0,\"bcy_rate\":122,\"customer_id\":582535000000092473,\"rate\":122,\"quantity_invoiced\":2,\"quantity_packed\":2,\"quantity_shipped\":2,\"unit\":\"qty\",\"tax_id\":4815000000044043,\"tax_name\":\"Sales Tax\",\"tax_type\":\"tax\",\"tax_percentage\":12,\"item_total\":244,\"is_invoiced\":true,\"image_id\":2077500000000002000,\"image_name\":\"dell.jpg\",\"image_type\":\"jpg\"}],\"notes\":\"Sample Note\",\"terms\":\"Terms and Conditions\",\"discount\":\"0%\",\"is_discount_before_tax\":true,\"discount_type\":\"entity_level\",\"shipping_charge\":7,\"delivery_method\":\"FedEx\",\"adjustment\":0,\"pricebook_id\":4815000000044054,\"salesperson_id\":4815000000044762,\"adjustment_description\":\"Just an example description.\",\"is_inclusive_tax\":false,\"exchange_rate\":1,\"template_id\":4815000000017003,\"documents\":[{}],\"billing_address_id\":4815000000017005,\"shipping_address_id\":4815000000017005}";


parameters=map();
parameters.put("JSONString",data);
parameters.put("authtoken","60148dd4ebe13b5236a609bd2b5a7674");
parameters.put("organization_id",643480296);
parameters.put("ignore_auto_number_generation",false);
parameters.put("scope","Zohoinvetory/inventoryapi");
resp_two = postUrl(" https://inventory.zoho.com/api/v1/salesorders",parameters);

And it generates the following error

{"code":4,"message":"Invalid value passed for customer_id"}

And the data variable is the customer_id.

Thanks!
