Testing
Choose the right way to validate your integration in Sandbox.
Testing
Bead supports several ways to validate your integration in Sandbox. This section helps you choose the right test method and links to a step by step guide for each one.
Choosing a Test Method
For most integrators, Klarna is the recommended default. It exercises the full end to end payment flow, create payment, hosted checkout, completion, and webhook or status confirmation, without requiring any real assets. Klarna provides sandbox test credentials, so you can prove your integration works before touching a live wallet or crypto network.
Pick your test method based on your terminal type and what you need to prove.
Klarna (recommended)
Virtual and physical
No. Uses Klarna sandbox test credentials
The default way to prove the full payment flow works, on either terminal type
Venmo
Virtual only
No. Sandbox does not draw from a live wallet
Validating the wallet redirect and QR flow on a virtual terminal
PayPal
Virtual only
No. Uses a sandbox PayPal test account
Validating the wallet approval flow on a virtual terminal
Crypto (USDC, BTC, Lightning)
Virtual and physical
Yes. Live blockchain networks, real assets plus network fee tokens
Only when you specifically need to validate a crypto tender
Start here
If you only need to confirm that your API keys, terminal configuration, hosted payment page, and webhooks all work together, run a Klarna test first. It is the fastest path to a completed payment and needs no funded wallet.
If you are integrating on a virtual terminal and want to validate wallet based tenders, you can also test Venmo and PayPal. Both complete in Sandbox without drawing from a live account.
Reach for crypto testing only when a crypto tender is in scope for your integration. Sandbox crypto payments run on live blockchain networks and require real assets plus a network fee token, so keep test amounts small.
