Rate limiting¶
To prevent excessive load on our systems, we limit the number of API calls that a provider can make per minute before the API returns HTTP/1.1 429 Too Many Requests.
The following table lists the rate limits per endpoint at the time of writing. We strive to keep this information up-to-date. However, we cannot guarantee that it always will be. Booking.com reserves the right to:
- Change these limits at any time, without prior notice.
- Impose other limits on specific accounts.
