SplatDev.Payments.BancoInter 1.0.4

SplatDev.Payments.BancoInter

Banco Inter payment gateway integration for SplatDev.Payments — models, settings, and API contracts for Pix, Boleto, and Banking operations with Banco Inter (Brazil).

Compatibility

Installation

dotnet add package SplatDev.Payments.BancoInter

Configuration

BancoInterSettings

using SplatDev.Payments.BancoInter;

var settings = new BancoInterSettings
{
    ClientId = "your-inter-client-id",
    ClientSecret = "your-inter-client-secret",
    Sandbox = true,                          // false for production
    CertificatePath = "/path/to/cert.pem",    // Required for production (mTLS)
    CertificateKeyPath = "/path/to/key.pem"   // Required for production (mTLS)
};

// Endpoints are derived automatically
Console.WriteLine(settings.BaseUrl);  // https://cdpj-sandbox.partners.uatinter.co
Console.WriteLine(settings.TokenUrl); // https://cdpj-sandbox.partners.uatinter.co/oauth/v2/token

appsettings.json

{
  "BancoInter": {
    "ClientId": "your-inter-client-id",
    "ClientSecret": "your-inter-client-secret",
    "Sandbox": true,
    "CertificatePath": "/path/to/cert.pem",
    "CertificateKeyPath": "/path/to/key.pem"
  }
}

Sandbox vs Production

Important: Production requires mTLS with a valid PEM certificate and private key. Both CertificatePath and CertificateKeyPath must be set.

Models

Pix

Boleto

Banking

Usage

using SplatDev.Payments.BancoInter;

// 1. Get OAuth token
var token = await GetTokenAsync(settings);  // POST {TokenUrl} with client_credentials

// 2. Create a Pix charge
var charge = new InterPixCharge
{
    Calendario = new() { Expiracao = 3600 },
    Valor = new() { Original = "49.90", ModalidadeAlteracao = 0 },
    Chave = "customer-pix-key@email.com",
    SolicitacaoPagador = "Order #1234"
};

// POST {BaseUrl}/cob/v2/cob with Bearer token

// 3. Issue a Boleto
var boleto = new InterBoleto
{
    SeuNumero = "INV-001",
    ValorNominal = 199.90m,
    DataVencimento = DateTime.UtcNow.AddDays(7),
    Pagador = new()
    {
        Nome = "John Doe",
        CpfCnpj = "12345678901",
        Endereco = new() { Cidade = "Sao Paulo", Uf = "SP" }
    }
};

// POST {BaseUrl}/cobranca/v3/boletos

Dependencies

No third-party SDK dependencies — this is a model/contracts library. HTTP calls should be implemented using HttpClient or RestSharp by the consuming application.

Limitations

• Model/contracts library only. No service layer, DI extensions, or HTTP client included.
• mTLS certificate management is the caller's responsibility.
• Token lifecycle (refresh before expiry) must be handled by the consuming app.
• Webhook signature verification not built in.

Changelog

1.0.4 — 2026-08-24

Removes a dashboard screenshot that showed an error toast. It was captured against a site where this plugin's API was unreachable, so it advertised a broken dashboard. No screenshot is better than a misleading one; a replacement will be taken against a working install.

1.0.3 — 2026-08-24

Package metadata only: the listing now carries an icon and search tags, and the project and repository links point at the organisation that actually hosts this code. No code changes.

1.0.2 — 2026-08-24

This package now keeps a changelog. Earlier releases predate it and are not reconstructed here — consult the repository history for those. From this version on, every release records what changed for someone using it.
