Frequently Asked Questions
Questions Founders & Engineering Leaders Ask
How do you handle third-party API rate limits and downtime?+
We engineer asynchronous queue buffers (using Redis and BullMQ) with exponential backoff retries and dead-letter storage. If a third-party API degrades or hits rate limits, incoming requests are safely queued and retried without losing transaction data.
