Getting Started with Prysm

Everything you need to start taking payments — from zero hardware to a full countertop setup. New here? The step-by-step Merchant Manual walks through everything in plain language.

1. Onboard (5 minutes)

Create your account — business details, then identity verification through our secure portal. Your account activates automatically when verification completes, usually within minutes. Your API key is shown once during signup — save it somewhere safe.

2. Take payments — pick your style

Browser terminal (no hardware)

Open Dashboard → + New Chargeon any phone, tablet, or computer. Enter the amount, key in the customer's card, done. A tablet at your counter is a full register.

Payment links (remote & invoices)

Generate a link from the same page — card or USDC stablecoin (1.5% flat) — and text or email it to your customer. They pay from anywhere; you see it in your dashboard instantly.

Countertop card reader (tap & chip)

Order a Prysm smart reader (~$249, no contract). During reader setup it shows a registration code — enter it in Dashboard → + New Charge → Card Reader and your dashboard drives the device: send an amount, the customer taps or inserts, payment lands in your account. Works with the POS counter setup you already have — the reader is the only new hardware.

3. API — connect your own software

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

Charge a card

curl https://prysmsolutions.io/api/charge \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "amount": 2500,
    "paymentMethodId": "pm_xxx",
    "description": "Order #1234",
    "customerEmail": "customer@email.com"
  }'

Amounts are integer cents ($25.00 = 2500). Tokenize the card on your checkout page to get a paymentMethodId.

Create a payment link

curl https://prysmsolutions.io/api/payment-link \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "amount": 10000, "method": "usdc", "description": "Invoice 42" }'

method: "card" or "usdc". Returns a URL your customer opens to pay. Links expire in 24 hours.

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, run the Prysm terminal on any tablet or phone, add a smart reader for tap & chip. No monthly fee, no contract, cancel anytime — compare that to what you're paying now.

Pricing

  • Cards: 3.15% + $0.40 per transaction — all-in, nothing else deducted
  • USDC stablecoin: 1.5% flat
  • No monthly fees, no setup fees, no contracts
