Payload C# Library

A C# library for integrating Payload.

Installation

1) Download

Download the latest version from GitHub.

2) Include in Project

Include the Payload folder in your Visual Studio project.

NuGet

dotnet add package payload-api

Get Started

Once you've included the Payload C# library in your project, include the Payload namespace to get started.

All Payload objects and methods are accessible using the pl static class.

API Authentication

To authenticate with the Payload API, you'll need a live or test API key. API keys are accessible from within the Payload dashboard.

using Payload;

var pl = new Payload.Session("secret_key_3bW9JMZtPVDOfFNzwRdfE");

Creating an Object

Interfacing with the Payload API is done primarily through Payload Objects. Below is an example of creating a customer using the pl.Customer object.

// Create a Customer
var customer = await pl.Customer.CreateAsync(new
{
    email = "matt.perez@example.com",
    name = "Matt Perez"
});

// Create a Payment
var payment = await pl.Payment.CreateAsync(new
{
    amount = 100.0,
    payment_method = new pl.Card(new
    {
        card_number = "4242 4242 4242 4242"
    })
});

Accessing Object Attributes

Object attributes are accessible through both dot and bracket notation.

// Dynamic
Console.WriteLine(customer.name);

// Compile-time checking
Console.WriteLine(customer["email"]); 
Console.WriteLine(customer.Data.email);

Updating an Object

Updating an object is a simple call to the UpdateAsync object method.

// Updating a customer's email
await customer.UpdateAsync(new { email = "matt.perez@newwork.com" });

Selecting Objects

Objects can be selected using any of their attributes.

// Select a customer by email
var customers = await pl.Customer
    .FilterBy(new { email = "matt.perez@example.com" })
    .OneAsync();

Use the pl.Attr attribute helper interface to write powerful queries with a little extra syntax sugar.

var payments = await pl.Payment
    .FilterBy(
        pl.Attr.amount.gt(100),
        pl.Attr.amount.lt(200),
        pl.Attr.description.contains("Test"),
        pl.Attr.created_at.gt(new DateTime(2019,2,1))
    )
    .AllAsync();

Testing the Payload C# Library

Tests are contained within the PayloadTests/ directory. To run tests enter the command in terminal

API_KEY=your_test_secret_key dotnet test
