Integrate the Integrated POS into your application using the .NET library.

Installation

  1. Place the PosIntegrado.Api.dll and PosIntegrado.Api.xml files provided in the release package into your project’s libs/ directory.
  2. Add a reference to the PosIntegrado.Api.dll file within your project.

Key namespaces

Include the following key namespaces in your code:

using PosIntegrado.Api;
using PosIntegrado.Api.Abstractions;

Connector creation

Create a connector instance to communicate via USB or HTTP (Network) using the respective methods:

Output HTTP connection

var connector = Connector.CreateHttp("192.168.1.100", 8080);

Output USB connection

var connector = Connector.CreateUsb("COM3");

Error handling

Check the Result<T> pattern to handle expected business logic rather than relying on exceptions:

var response = connector.SomeOperation(request);

if (response.IsSuccess)
{
    // Proceed with response.Value
}
else
{
    // Handle error with response.Error
}

Sale flow example

Review the following example demonstrating the structure of a single-step sale flow:

// 1. Initialize connector
var connector = Connector.CreateHttp("192.168.1.100", 8080);

// 2. Build the request
var request = new SaleRequest 
{
    Amount = 15000,
    SaleType = SaleType.Card,
    PrintOnPos = true
};

// 3. Execute the sale
var result = connector.Sale(request);

// 4. Handle the result
if (result.IsSuccess)
{
    var saleResponse = result.Value;
    Console.WriteLine($"Sale Approved: {saleResponse.AuthorizationCode}");
}
else
{
    Console.WriteLine($"Sale Failed: {result.Error.Message}");
}
