Payment integration for platforms
Card payments, marketplaces and payouts built into your platform, not bolted on.
63Digital builds payments into platforms: Stripe Connect marketplaces that take a fee and pay out to sellers, in-person payments with Stripe Terminal and Tap to Pay on iPhone, ticketing checkouts on Stripe and Square, and a checkout that runs on seven gateways. We build the webhooks, refunds, reconciliation and fee billing behind them, not just the pay button.
Platforms we work with
Stripe
Marketplaces, in-person payments and Tap to Pay on Stripe, with the fees, refunds and reconciliation done properly.
Square
Square online payments and marketplace fees, built alongside Stripe and kept in lockstep.
Apple & Google Wallet
Tickets, vouchers and memberships that live on the customer's phone, not in their inbox.
How to, from jobs we've done
How to build a Stripe Connect marketplace in .NET
Let Stripe host merchant sign-up, and treat a merchant as ready only when Stripe confirms payments and payouts are both switched on with nothing outstanding. Your platform creates each payment, passes the merchant their share and keeps its fee as the money moves. Refunds come back out of the merchant's share, while your fee stays with you.
How to keep Stripe keys off mobile apps and plugins with a reverse proxy
Put a gateway between your apps and Stripe so the apps never hold your platform's Stripe secret key. Each app or plugin gets its own key that you can withdraw. The gateway works out which merchant it belongs to, adds the merchant's account and your fee on the server, and only passes on the Stripe requests you've approved.
How to recover Stripe interchange fees from connected accounts automatically
Stripe reports the card network costs behind every payment on your merchants' accounts. Import that report daily, count each fee once, and total what each merchant owes. Then collect it from their Stripe balance on a schedule, labelling each bill by merchant and period so that a retry can never bill anyone twice.
How to take payments with Tap to Pay on iPhone using Stripe Terminal
Tap to Pay turns a merchant's iPhone, or an NFC Android phone, into a contactless card reader through Stripe Terminal. Your app needs Apple's approval, each merchant needs their own Stripe location so payments land with the right business, and payments are created on your server with your fee. Most of the work is handling phones that can't tap.
How to build a ticketing marketplace on Stripe Connect and Square
Make the promoter the merchant of record: connect their own Stripe or Square account, take payments on it, and take your cut as a platform fee. Cap that fee to fit both providers' limits, set up Apple Pay and Google Pay on every promoter's account, record the real processing fee, and fix every bug on both providers together.
How to add Apple Wallet and Google Wallet tickets to your platform
Add an Apple Wallet pass and a Google Wallet save link to each ticket, both signed with credentials Apple and Google issue to you. Keep the QR code exactly as it is so door scanners still work, serve passes from unguessable links that need no login, and switch wallets on per organiser once each has been verified.
