Package Overview

Authlink.Identity.Client.Core is a low-level, dependency-free library that defines interfaces, data contracts, and shared models used by client SDKs that integrate with Authlink Identity.

It is intended to be consumed by higher-level packages such as:

  • Authlink.Identity.Client.Http

Install

dotnet add package Authlink.Identity.Client.Core

Or via Package Manager:

PM> Install-Package Authlink.Identity.Client.Core

Purpose

This package serves as a foundation layer, enabling:

  • Abstraction of token and authentication flows
  • Decoupled, testable client implementations
  • Plug-and-play support across .NET environments (console, web, serverless)
  • Rich error handling with detailed error information via ErrorOr<T>

What's New in v2.3.0

Breaking Changes - Registration Link Flow:

  • Removed ValidateInvitationCodeRequest / ValidateInvitationCodeResponse - This endpoint no longer exists
  • Removed ValidateInvitationCodeAsync method from IIdentityClient

New Features - Two-Step Registration Link Validation:

  • Added VerifyRegistrationLinkRequest / VerifyRegistrationLinkResponse for verifying registration link tokens (Step 1)
  • Added ValidateRegistrationLinkRequest / ValidateRegistrationLinkResponse for validating tokens with invitation codes (Step 2)
  • Added VerifyRegistrationLinkAsync - Verify a registration link token and get recipient information
  • Added ValidateRegistrationLinkAsync - Validate a registration link with invitation code and create registration session

See CHANGELOG.md for full version history.

Error Handling

All methods return ErrorOr<T> for explicit error handling:

var result = await client.TokenAsync(request);

if (result.IsError)
{
    var error = result.FirstError;
    Console.WriteLine($"Error: {error.Code} - {error.Description}");
    return;
}

var response = result.Value;
Console.WriteLine(response.AccessToken);

Error Types

  • HttpRequestFailed - HTTP errors with status codes and reason phrases
  • ProtocolError - OAuth 2.0 / OIDC protocol errors from the server
  • NetworkError - Connection and network-related failures
  • OperationTimeout - Request timeout errors
  • OperationCancelled - Cancelled operations
  • DeserializationFailed - JSON parsing errors
