Limitations
- All integrations depend on third-party API availability. If a platform's API is down, sync to that platform is paused.
- Rate limits on third-party APIs may slow initial data import for very large catalogs.
- StackKnack does not currently integrate with Amazon, Grailed, Mercari, or Poshmark.
- Adding new integrations requires development by the StackKnack team. Custom integrations are not self-service.
Example
A store connects Shopify, eBay, and Clover. A customer buys a pair of shoes in-store via Clover. StackKnack receives the Clover sale event, decrements the central inventory, and pushes updated quantities to both Shopify and eBay within 30 seconds.
