Rate Limiting

To ensure fair and reliable service for all clients, the Flowbrite API enforces rate limiting using the token bucket algorithm. This algorithm allows short bursts of requests while enforcing a maximum sustained rate over time.

How It Works

• Each client has a “bucket” of tokens.
• Every API request consumes one token.
• Tokens are automatically refilled at a fixed interval.
• If the bucket is empty, requests may be queued (up to a limit) or rejected until new tokens become available.

API Limits

What does this mean for you?

• You can make up to 180 requests in a quick burst.
• After a burst, tokens are refilled at a rate of 30 every 10 seconds (so, max 180 per minute).
• If you exceed the limit, up to 60 requests will be queued and processed in FIFO order as the tokens refill.
• If you exceed the limit, you will receive a 429 Rate Limit Exceeded response.
