Api Product Quantity Update (200.000 Product)

I can only update the product quantity via API.

How do I update 200000 product quantity with 30 minute intervals.

/api/products

Example:

{
"product_id": "324",
"amount": "542"
},
{
"product_id": "278",
"amount": "320"
},

{
"product_id": "800",
"amount": "100"
},

{
"product_id": "810",
"amount": "20"
}

.....200000 product

or

{
"product_code": "9786054760510",
"amount": "542"
},
{
"product_code": "9786054760527",
"amount": "320"
},

{
"product_code": "9786056854859",
"amount": "100"
},

{
"product_code": "9786054760695",
"amount": "20"
}

......200000 product

Looks like PUT method is not supported for the /api/products URL in API

It may be better to update this data directly in the database (cscart_products table is you are using simple products). You may DDOS your own server with such amount of API requests.
