Shopify → eBay sync
A multi-channel merchant was selling on both Shopify and eBay. Every product update in Shopify — title, price, inventory, description — had to be manually replicated in eBay. With hundreds of SKUs, this was a daily time drain and a constant source of listing inconsistencies.
The core challenge was discovery: eBay listing IDs weren't stored in a clean field — they were buried inside Shopify's Outlinks metafields as raw URLs. We had to build a reliable parser before we could even attempt a sync.
Built a GraphQL-based integration querying Shopify Admin API at scale to fetch Outlinks metafields, parsed out eBay listing IDs from the URL format, and wired a Sidekiq background job to push Shopify product changes to eBay automatically. Includes retry logic and failure logging for each failed sync.
