n8n errors / Rate limit
AxiosError: Request failed with status code 429
Cause
The destination API returns 429 because n8n is sending requests faster than its rate limit allows.
Fix
Add a Wait node between iterations to space out requests. Enable batching in the HTTP Request node Options with a small batch size. Check your API tier - some providers lower limits when balance drops. For webhook-triggered flows, add queue or debounce logic to avoid bursts.
