From your offer to payment

Your offer, ready for payments.

  1. 1

    Add your product

    Define your product or service package, its scope and price. Start in the sandbox.

  2. 2

    Create a path to payment

    Use the SDK or API to create a payment link. The docs help you and your coding assistant integrate.

  3. 3

    Open your recipient account and sell

    Fill in the recipient application in the dashboard. Infi opens a receiving account in your name at the payment provider; in Brazil, sale proceeds go to that account after verification.

billing.ts@beinfi/sdk
import { Infi } from "@beinfi/sdk";

const infi = new Infi({
  secretKey: process.env.INFI_SECRET_KEY!
});

const { url } = await infi.links.create({
  product: {
    key: "mensal",
    name: "Mensal",
    pricingModel: "subscription",
    billingCycle: "monthly",
    basePrice: "299.00"
  }
});

Run on your server with your sandbox secret key. The key is the product's stable identifier — running this again creates nothing new.

FAQ

Before you start.

How much does it cost?

Fee per charge in Brazil, by method: Pix 1.99% + R$ 1.00; card one-shot 5.9% + R$ 1.00. Pix and card in a test environment. No monthly fee. High volume: talk to us.

Can I bill by usage and by contract?

Yes. Recurring subscriptions, metered usage, tiered and volume pricing, per-customer rate cards and annual contracts — in one place, with automatic recovery of failed payments.

Do I need a payment provider account?

You don’t need to bring one. In Brazil, Infi opens a receiving account in your name at the payment provider, and identity verification is done through a payment provider link generated in the dashboard. Money from your sales goes to that account.

How do I activate live payments?

Test everything in the sandbox. To take real money, fill in the recipient application in the dashboard and complete identity verification through the payment provider link. The dashboard tells you when your account is ready to receive. Pix and card in a test environment.

When and how do I receive funds?

In Brazil, payment goes to your receiving account. Coverage outside Brazil depends on payment method, market and account eligibility.
