Getting started
From sign-up to your first sandbox API key.
Complete these steps once per organisation. After that, everything else — destinations, more API keys, inviting teammates — is incremental.
Create an account
Sign up with your work email. You'll be asked to verify your email address before you can sign in. A personal organisation is created for you automatically.
Register your merchant
Go to Account → Merchant and fill in your company's details: legal name, registration number, country of incorporation, and contact information.
This is the record your KYB assessment will be run against, so make sure the details match what's on your company registration documents.
Add a bank destination
Under Open Finance → Banks, connect the bank account where ARYZE should settle your payments. Each destination is tied to a currency and a payment rail (e.g. SEPA, Faster Payments).
See Bank destinations.
Create your first API key
Under Open Finance → API Keys, click Create API key. Pick a destination, set a webhook URL, and copy the client secret — it's shown once. See API keys for details.
Send a sandbox payment
Head to Open Finance → Playground to send a test payment using your new key without setting up a real checkout. Or follow the Quickstart to call the API directly.
