API rate limit
API rate limit is the maximum number of requests an API accepts per time window. Exceeding it returns HTTP 429 (Too Many Requests). Production workflows MUST handle rate limits gracefully — retry with exponential backoff, or queue + throttle.
More detail
Common rate limits: Stripe 100 req/s, OpenAI 500 req/min, Twilio 1 req/s, Gmail 250 quota units/s. Rule of thumb: throttle to 80% of the documented limit so bursts don't fail. n8n's HTTP node has built-in retry; Zapier's needs explicit error handlers; Make handles via the Sleep module.
