.NET bindings for the Plaid API

This library provides convenient access to the Plaid restful services. It's also available as NuGet package for .NET, Universal Windows Platform, Portable Class Library (Xamarin). Please drop me a note if you need specific target frameworks.

Usage

Public Client

  var client = new PlaidPublicClient(PlaidClient.EnvironmentDevelopment);

  var institutions = await client.GetInstitutions();

User Client

  var client = new PlaidUserClient("test_id", "test_secret", PlaidClient.EnvironmentDevelopment);
  var product = "connect";
            
  try
  {
      var response = await client.AddUser(product, "td", 
        new Credentials { Username = "plaid_test", Password = "plaid_good" }, null);
      
      // if response contains multi factor authentication, details will 
      // be wrapped in "Mfa" property
      if (response.Mfa != null)
          await client.StepUser(product, response.Mfa.AccessToken, new[] {"tomato"}, null);
      else
          // response.Accounts      -> Account information
          // response.Transactions  -> Transactions
          // response.Info          -> User information from this institution
  }
  catch (PlaidException e)
  {
      // Use this exception to capture Plaid API errors 
      // as specified in https://plaid.com/docs/#response-codes
      // Error details wrapped in e.Error
      // 
      // if using WCF, you can easily use WebFaultException to handle the error
      // throw new WebFaultException<Error>(e.Error, e.Error.StatusCode);
  }
  catch (Exception e)
  {
      // Something else happened here
  }
