question

Unfortunately we do not do temporary API rate limit increases, as in order for us to increase your API rate limits, you will have to go through an approval process where we verify that you are still hitting the rate limits even after optimizing all your API calls.

However, I see multiple solutions to your use case:

1. Use the CSV upload manually for each site, and then use a GET /items API call to get all the Clover Item IDs.

2. Use our BulkItems endpoint to create a bulk of inventory items.

Here is an example call with 2 items with the minimum required fields:

POST /v3/merchants/{
                {merchantId}}/bulk_items

Body:

{
    "items": [
        {
            "name": "item1",
            "price": 100
        },
        {
            "name": "item2",
            "price": 200
        }
    ]
}

Response:

[
    {
        "id": "SKEJQ5Z6NZ9E4",
        "hidden": false,
        "name": "item2",
        "price": 200,
        "priceType": "FIXED",
        "defaultTaxRates": true,
        "isRevenue": true,
        "modifiedTime": 1541097884000
    },
    {
        "id": "6VP1XV8E562G4",
        "hidden": false,
        "name": "item1",
        "price": 100,
        "priceType": "FIXED",
        "defaultTaxRates": true,
        "isRevenue": true,
        "modifiedTime": 1541097884000
    }
]

Note: You can pass in more fields, the same ones as the ones from our CreateItem endpoint.
