The demo app

Coastline, a working Tenant web app with a Customer app and a Business app.

Coastline is a small Tenant app built on the sandbox exactly as we recommend you build yours. It has its own server, which calls the Tenant API with its own credentials and verifies its own webhooks, and a web app that you can install on a phone's home screen. Each visitor gets a private workspace for 24 hours.

The Behind the scenes panel shows, live, every call the Coastline server makes and every signed webhook it receives.

Customer app#

Open an account through the onboarding screens, or skip them with the sandbox completion.
Link a bank with the bank-linking simulator, including a bank with its own sign-in.
Add funds, then confirm on the hosted screen with the new-device check and a PIN, or set up a passkey.
Pay Harbor Street Coffee by QR code, from balance or by bank.
Withdraw to the bank, and reset the PIN.

Open your own business account through the merchant onboarding screens, or use the demo shop.
Take payments with a QR code for an order, or a counter QR code where the customer enters the amount.
See payments as they arrive, and refund them; the merchant confirms each refund.
