The majority of the Recurly API v2 objects are supported, however there may be a few that are still in progress or were missed. Please report any questions or issues via Github.

The Official .NET Recurly API client library.

Compatible with Recurly API v2.

Versions >= 1.13.0 of this library are targeted against .NET v4.7. Versions < 1.13.0 are targeted against .NET v3.5.

If you use NuGet, simply run the following:

PM> Install-Package recurly-api-client

You may also visit our Releases page to download the latest version. Then add the Recurly.dll as a reference to your solution.

Alternatively, you can use use git to work with the latest changes in development.

git clone git://github.com/recurly/recurly-client-net.git C:\path\to\recurly

For more information about getting started with git, please check out the Github Guide for Windows.

To configure the library, you will need your API Key and site subdomain. The recommended way to configure the library is to statically initialize it:

// pageSize is optional and defaults to 200
Recurly.Configuration.SettingsManager.Initialize(apiKey, subdomain, pageSize);

We recommend doing this for compatibility with newer .NET frameworks as well as security. We also recommend you encrypt your api key at rest or use a secrets service. You should not store your api key in plain text on your system.

If you are using the legacy method of configuring with app.config or web.config, we strongly recommend updating your updating your application to use the above method.

The API documentation is available on our developer docs site. Examples can be found there for each API endpoint.

Although we do not officially support .NET core or standard at this moment, it is possible to use this library from those applications. One method is to vendor the source code, build the dll, and link directly to it from your project.

To build the library you can now use msbuild:

msbuild /p:Configuration=Release Recurly.sln

To use the dll, you can reference it in your .csproj file:

<ItemGroup>
  <Reference Include="Recurly">
    <HintPath>{pathToRecurlyLibrary}/Library/bin/Release/Recurly.dll</HintPath>
  </Reference>
</ItemGroup>

To create a resource, initialize it, set the desired parameters, then call Create(). The instance will be auto-updated with the new details from the server. Here is an example of creating an Account:

var account = new Account("123")
{
  FirstName = "John",
  LastName = "Smith"
};
account.Create();
Console.WriteLine(account.CreatedAt);

All resources have some kind of identifier. The API docs site should help you understand how to reference the resource you want. In the case of the Account, we can reference it by AccountCode. Call Get on a resource class to fetch the resource with the given identifier.

var account = Accounts.Get("123");

Sometimes, if you wish to enumerate many resources on the server, you will need to make multiple HTTP calls to the server. This is called pagination. Pagination in this library is handled by the RecurlyList class. An instance of this class can be created by calling List() on the plural-named resource class (e.g. Account -> Accounts). For example, suppose we wish to iterate over every account on our site:

// returns a RecurlyList instance
var accounts = Accounts.List();

// while the server still has accounts to give
while (accounts.Any())
{
  // iterate through each account in this "page"
  foreach (var account in accounts)
    Console.WriteLine(account);

  // fetch the next "page" of accounts
  accounts = accounts.Next;
}

It's also possible to sort and/or filter this stream of resources by passing in parameters to the List() method and using the FilterCriteria class. Here is an example of sorting and filtering accounts:

var filter = FilterCriteria.Instance               // create the instance
        .WithOrder(FilterCriteria.Order.Desc)      // order the results in "descending" order
        .WithSort(FilterCriteria.Sort.UpdatedAt)   // sort by the `UpdatedAt` property
        .WithBeginTime(new DateTime(2017, 1, 1))   // filter out any accounts updated before January 1st, 2017
        .WithEndTime(DateTime.UtcNow);             // filter accounts updated to this moment (could be any date after `BeginTime`)

// The first parameter of Accounts.List allows you to filter by the `State` of the account.
// In this case, let's only look at `Active` accounts.
var accounts = Accounts.List(Account.AccountState.Active, filter);
foreach (var account in accounts)
{
    Console.Write(account.AccountCode + ": ");
    Console.WriteLine(account.UpdatedAt);
}

Every List() method takes a FilterCriteria as the final parameter, but differs in the endpoint specific filters. The best way to learn about this is by looking at the source code or the code docs.
