Automating Order Fulfilment for a Game Top-Up Platform
A top-up website connected to the supplier’s API, so orders the owner used to fulfil by hand are now placed with the supplier automatically.

What they needed
InCharge.gg sells top-ups for mobile and live-service games. Each order had to be fulfilled by hand: the owner took the customer’s order, then placed it with his supplier himself.
He needed customers to be able to order and pay on their own, and the order to reach the supplier without him retyping it.
What we built
We built a top-up website and connected it to the supplier’s API:
- A game catalogue and a top-up checkout for each game.
- Payment by PayNow, GrabPay, Apple Pay, Google Pay and crypto.
- An integration with the supplier’s API, so a paid order is placed with the supplier automatically.
- Order tracking for customers, and a request form for games that are not listed yet.
Ordering, payment and fulfilment now run as one flow, from the customer’s checkout to the supplier.
What it does now
The step that used to need the owner, placing each order with the supplier by hand, is now automatic. A customer chooses a game, pays, and the order goes to the supplier through its API.
Customers can follow their order on the site, and ask for a game to be added if it is missing from the catalogue.
