My WordPress store needs to talk seamlessly with my seller accounts on Kinguin, Eneba, Driffle and Gamivo. Every time a key sells on one of those marketplaces, the corresponding stock on my site must adjust automatically, and vice-versa. I am not running WooCommerce or any other inventory plugin yet, so part of this job is recommending the most suitable WordPress solution (WooCommerce, a lightweight custom plugin, or any other option you prefer) and then wiring it to each marketplace’s API. Top priorities I have already identified: • Real-time stock updates so overselling never happens • Order synchronization that pushes marketplace sales into my WordPress back-office • Basic sales analytics pulled from all four channels so I can see totals in one place Deliverables • Stable API integrations for Kinguin, Eneba, Driffle and Gamivo, fully tested • A clean WordPress setup (or suggested plugin stack) that holds master inventory • Automatic two-way sync covering products, stock counts and order details • A simple dashboard or report inside WordPress that aggregates sales numbers • Step-by-step documentation so I can maintain the connections without coding knowledge Success is a live environment where I can add or remove stock in one place and watch it reflect everywhere within seconds, with each external order neatly recorded on my site. I am happy to provide existing API keys and marketplace documentation as soon as we start.
