# API rate limits

> How Fintoc applies rate limits to API and Widget requests, and how to handle `429 Too Many Requests` responses.

Fintoc applies separate rate limits to API requests and Widget connections. This page explains both limits and how to handle `429 Too Many Requests` responses. The following limits apply:

1. **Organization rate limit:** Up to 100 requests per second for each organization across the Fintoc API.
2. **Widget connection rate limit:** Up to 100 requests per 130-second window for each organization across Widget connections.

Treat these limits as maximums. Keep your request volume below them, and handle rate-limited responses.

Fintoc lowers limits to prevent abuse and raises limits for integrations that require request volumes above the defaults. Contact support at least one month before you need a higher limit.

## Handle rate limiting

Watch for `429 Too Many Requests` responses. Retry each rate-limited request with exponential backoff. Start with a 1-second delay, then double the delay after each attempt: 1, 2, 4, 8, and 16 seconds. Retry up to 5 times. Add a random delay of up to 1 second to each retry to prevent clients from synchronizing their requests.
