API Limits

In order to allow access to all sellers and maintain a stable platform, the Seller Portal has the following limits on the number of files that can be sent within an hour.

Limits by Type

Limits by IP Address

A single IP address may “ping” our APIs up to 500 times per minute.  This includes both PUT & GET calls.  If your IP address exceeds 500 requests per minute, your IP address will be throttled for 15 minutes.  You will receive an error “rate limited”.  After 15 minutes, you may continue to send calls. 

Errors received

If you receive a 403 error, you will need to wait 60 minutes from the time of the first API call to continue.  Example, if a seller has posted over 600 catalog files from 11:05 to 11:58, they will need to wait until 12:05 to post the next catalog request.
