Draft Order API Not Overriding Variant Default Price with Custom Price

I am experiencing an issue with the Shopify Draft Order API (version 2025-01). I would like to set a custom price by including both the variant_id and price field in a draft order line item, but the created order still uses the variant’s default price.

Below is an example of my request payload:

{
“draft_order”: {
“line_items”: [
{
“variant_id”: 47407549481273,
“quantity”: 2,
“price”: “50.00”,
“properties”: [
{
“name”: “Custom Option”,
“value”: “Blackout 90%”
},
{
“name”: “Size”,
“value”: “25’’ x 13’'”
}
]
}
]
}
}
Are there any settings or API version considerations that might cause this issue?

Thank you for your assistance.
