Overview
This page gives you the big picture: what Wallee is, the core concepts you will meet everywhere in the platform, and how a payment flows through the system. Five minutes here will make everything else in this documentation easier.
What is Wallee?
Wallee is a payment platform for omnichannel payment processing:
- E-commerce — hosted payment page or iframe checkout for your webshop, with ready-made plugins for all major shop systems.
- In-store — card terminals fully integrated into the same platform and reporting.
- Unattended — payments at vending machines, kiosks and charging stations.
One contract, one portal, one API — every channel feeds into the same transactions, settlements and analytics.
Security built in: Wallee is PCI DSS Level 1 compliant. Payment forms are generated and hosted by Wallee (payment page or iframe), which keeps you as a merchant out of most of the PCI scope.
Core concepts
These terms appear throughout the portal, the API and this documentation:
| Concept | What it means |
|---|---|
| User | A person (human user) or system (application user) that logs in. One user can access several accounts. |
| Account | Your contractual home: plan, billing information, invoices and user management. Created automatically when you sign up. |
| Space | The operational workspace inside an account: transactions, payment methods, terminals, settlements and settings live here. By default one account has one space. |
| Space view | A lightweight variant of a space — share the same configuration but separate presentation, e.g. country shops of the same webshop. |
| Transaction | A single payment. Every transaction follows the same standardized state flow, regardless of payment method or channel. |
| Processor & connector | The route a payment takes to the acquiring side. Conditions let you route transactions between multiple connectors. |
| Manual task | A structured request for your decision when something cannot be processed automatically (e.g. suspected fraud). |
See Account Structure for a deeper explanation of users, accounts, spaces and permissions.
How a payment flows
Every transaction on the platform follows the same standardized process — whatever the payment method:
Pending → Confirmed → Processing → Authorized → Completed → Fulfill
↳ Failed ↳ Voided / Decline
The final states (Fulfill, Decline, Voided, Failed) give you a clear signal whether to ship goods or release services. You will find every transaction and its state in your space under Payment > Transactions.
