API Documentation v2.0

PagaSul Global
Payments API

Seamless transactions and local payment methods across LATAM. Low fees, high conversion rates, one single integration.

APM-First Architecture

We prioritize local payment preferences — Pix, Mercado Pago, wallets, bank transfers — over generic card processing, resulting in higher conversion rates.

Flexible User Flows

Support for both Host-to-Host (H2H) embedded experiences and Redirect flows lets you tailor checkout based on your app's capabilities.

Enterprise-Grade Security

HMAC-SHA256 request signing and integer-based merchant identification ensure transaction integrity through strict authentication protocols.

Simple Integration

One API call to create a payment

create-payment.js

  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "signature": generateSignature(payload, secretKey)
  },

    client_payment_id: "payment_35",
    amount: 12.34,
