Built the way .NET developers expect
net8.0 target, System.Text.Json serialization, and one reusable HttpClient managed for you. Fully async from top to bottom.
POCO param classes with null properties omitted automatically, and a typed exception hierarchy including RateLimitException with RetryAfter.
Exponential backoff with jitter on rate limits, server errors and network failures. Honors Retry-After, never retries non-idempotent requests.
Stripe-style signature verification with constant-time comparison, so publish and engagement events reach your app safely.
Posts, media uploads, folders, accounts, analytics, best times, the social inbox and webhooks. Every v1 endpoint, one client.
The whole API, not a subset
The .NET SDK covers every v1 endpoint, the same surface as the REST API.
Create, schedule, update and publish posts, stories and reels across all 11 platforms, including X threads and platform-specific options.
Upload images, video and PDFs from files, URLs or base64, up to 1GB via presigned uploads, with automatic compatibility checks per platform.
Pull per-post and per-account metrics, workspace overviews and best times to post, ready for your own dashboards.
Manage the social inbox from code: list DM, comment and mention conversations, pull full message threads, mark them read and send replies.
Subscribe to publish, failure and engagement events with signed payloads and a rotate-secret endpoint.
List connected accounts and organize content into folders, so your integration mirrors how the team works.
Search and validate taggable locations for platforms that support them.
