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.
