Throttling

Newegg Marketplace API supports large variety of application and process millions of API requests daily. To maintain stable service with a high level of availability, Newegg Marketplace limits the API usage.

Per Seller

Rate limiting of each API request is based on per-seller basis.

Rate Limit

Rate limits are divided into minute intervals. This means you have a maximum number of requests you can submit to a specific function in a one-minute period.

Datafeed Limit

Datafeed related functions have the hourly limitation of request and the maximum size of each request. This means you have a maximum allowance of requests you can submit to a specific function in a one-hour period. And each request cannot exceed the maximum size limitation.

The response if you exceed the limit:

Example: XML, Response

<?xml version="1.0" encoding="utf-8"?>
<Errors>
    <Error>
        <Code>DF012</Code>
        <Message>Your feed with request ID: 2291326430 exceeded the hourly allowance and cannot be processed. Please submit your feed again after 2016-12-16 11:05:00.</Message>
    </Error>
</Errors>

Example: Json, Response

[
    {
        "Code": "DF012",
        "Message": "Your feed with request ID: 2291326430 exceeded the hourly allowance and cannot be processed. Please submit your feed again after 2016-12-16 11:05:00."
    }
