Create Item | purchase_rate is always ignored

Create Item | purchase_rate is always ignored

Description:

I am encountering an issue when using the Create Item API in Zoho Inventory. Specifically, when I attempt to create an item using the following endpoint:

Payload:

{
    "group_id": "99999999999999999",
    "name": "Item Name",
    "sku": "012345",
    "ean": 9999999999999999,
    "attribute_name1": "Size",
    "attribute_option_name1": "Big",
    "rate": 80,
    "purchase_rate": 70,
    "unit": "pcs",
    "status": "active",
    "group_name": "Group Name"
}

Issue Details:

While the item is successfully created and assigned to the correct item group (using the group_id and group_name fields), the purchase_rate field is being ignored, and the item is created with a purchase_rate of 0.00.

Interestingly, when I create items using the itemgroups endpoint (where I build the payload with all the respective items inside the items key), the purchase_rate is correctly applied and reflected.

Expected Behavior:

The purchase_rate should be correctly applied when creating an item via the Create Item endpoint, just as it is when using the itemgroups endpoint.

Request for Assistance:

Could you please help me understand why the purchase_rate is being ignored when using the Create Item endpoint? Is there a specific field or additional configuration that I need to include in the payload to ensure the purchase_rate is correctly set?

I would appreciate your assistance in resolving this issue.

Thank you for your support.
