Frequently Asked Questions
How does it work?
Our system uses tokens to uniquely identify FNSKUs and track successful API conversions, on a simple pay-as-you-go model. Billing occurs only for successful conversions — Fnskus that encounter errors, or that have already been processed successfully, will not result in any charges.
What's included?
Every plan includes API integration documentation, portal access to monitor and download reports, and a browser extension for swift web-based integration.
Can I look up multiple marketplaces?
Yes — you can search up to four marketplaces in a single request. Note that each successful multi-marketplace response consumes two tokens.
Can I have multiple subscriptions?
Yes, multiple subscriptions can be active at the same time. If you no longer want a previous plan, be sure to cancel it — subscribing to a new plan does not replace the current one.
