Other platforms & custom builds

The XML, CSV and JSON feeds are standard files that any import tool or custom scheduled job can consume — you're not limited to WooCommerce or Shopify.

General guidance

• Use SKU as your unique key for create/update logic.
• Prefer the update feed for frequent syncs, and reconcile against the full feed periodically.
• Fetch server-side on a schedule, and handle a temporarily unavailable feed gracefully — retry with backoff rather than tight loops.
• Keep your total downloads inside the hourly allowance. Every currency and format you fetch, plus any testing, counts against the same account key — including requests from other servers or environments.
• Handle 429 (rate limit reached — wait for the next hour) and 403 (account key blocked — contact your account manager) explicitly. Neither is retryable, and retrying a 429 is what causes a block.
• Follow the polling best practices and fair usage policy.
