Lob.Net

Lob.Net is a wrapper for the Lob.com API. It follows the latest technology regarding dependency injection and strong typing.

This project is actively maintained and is in its early alpha stage. Many breaks will be introduced until stability is reached.

Installation

Install package:

PM> Install-Package Lob.Net

Setup

Load the Lob interfaces in your Startup.cs as such:

public Startup(IConfiguration configuration)
{
    Configuration = configuration;
}

private IConfiguration Configuration { get; }

public void ConfigureServices(IServiceCollection services)
{
    services
        .AddLob(options => options.ApiKey = Configuration["Lob:ApiKey"]);
}

Include your API key in the appsettings.json

{
  "Lob": {
    "ApiKey": "test_api_key"
  }
}

Usage

Inject the appropriate interface in your controller in order to send postcards, letters, etc.

Postcards

[Route("api/[controller]")]
public class PostcardsController : Controller
{
    private readonly ILobPostcards lobPostcards;

    public PostcardsController(
        ILobPostcards lobPostcards
    )
    {
        this.lobPostcards = lobPostcards;
    }

    [HttpPost]
    [Route("")]
    public async Task SendPostcard()
    {
        try
        {
            var result1 = await lobPostcards.CreateAsync(new PostcardRequest
            {
                From = new AddressReference(new Address
                {
                    Name = "Jean-Sébastien Goupil",
                    Company = "JSGoupil, LLC",
                    AddressLine1 = "123 Main Street",
                    AddressCity = "Seattle",
                    AddressState = "WA",
                    AddressZip = "98103",
                    AddressCountry = "US"
                }),
                To = new AddressReference("adr_738379e5622a9f04"), // Saved address in LOB
                Front = "tmpl_7e7fdb7d1cb261d", // Saved template in LOB
                Back = "tmpl_7e7fdb7d1cb261d", // Saved template in LOB
                MergeVariables = new Dictionary<string, string>
                {
                    {"variable_name", "Jean-Sébastien" }
                }
            });
        }
        catch (LobException ex)
        {
            throw ex;
        }
    }
}

WebHooks .NET Core 2

You need to install this NuGet package:

PM> Install-Package Lob.Net.Formatters

The webhooks must be configured with Mvc with the following code:

services.AddMvc()
	.AddLobFormatters();

Create a controller and actions like this:

[AllowAnonymous]
[Produces("application/json")]
[Route("api/[controller]")]
public class ExternalsController : Controller
{
    public ExternalsController(
    )
    {
    }

    [HttpPost]
    [Route("postcard")]
    public IActionResult LobPostcard([FromBody] Lob.Net.Models.LobEvent<Lob.Net.Models.PostcardResponse> evt)
    {
        // If you know exactly which type you are getting.

        return Ok();
    }

    [HttpPost]
    [Route("object")]
    public IActionResult LobObject([FromBody] Lob.Net.Models.LobEvent evt)
    {
        // If you accept any type, use the non-generic version.
        if (evt.EventType.Resource == Lob.Net.Models.EventTypeResource.Postcards)
        {
            var postcardEvent = evt.ToPostcard();
        }

        return Ok();
    }
}
