My integration keeps getting 429 Too Many Requests, how do you fix it?

A 429 means your integration is exceeding BigCommerce’s API quota for your plan. The fix is rarely “ask for a higher limit”, it’s adding exponential backoff, respecting the X-Rate-Limit-Time-Reset-Ms header, batching writes, and moving heavy reads to the GraphQL Storefront API or webhooks instead of polling. We rebuild the integration so your ERP, PIM, or shipping sync stays inside the quota and stops dropping data.
