Getting Started with Prysm

Everything you need to start taking payments. New here? The step-by-step Merchant Manual walks through everything in plain language.

1. Onboard

Create your account, then enter your business, owner, and bank details once in Take payment → Card. Card payments, and recording cash sales, turn on when our processor approves your business. Need an API key for your own software? Email support.

2. Take payments — pick your style

Browser terminal (no hardware)

Open Dashboard → + New sale on any phone, tablet, or computer. Enter the amount, key in the customer's card, done.

3. API — connect your own software

Every account includes API access. Authenticate with your API key as a Bearer token.

Issue a refund

curl https://prysmsolutions.io/api/refund \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "transactionId": "txn_id_from_charge", "amount": 1000 }'

Already on Square, Toast, or Clover?

Those devices are locked to their own processors — no one can run other payments on them. The switch: keep your counter setup and run Prysm on any tablet or phone. No monthly fee, no contract, cancel anytime — compare that to what you're paying now.
