Fuxux API Reference — REST Docs for Scheduling
REST API documentation for Fuxux. Schedule and publish to 13 social platforms, manage connected accounts, upload media, generate AI captions, and get signed webhooks with API key requests.
The interactive OpenAPI reference on this page needs JavaScript. Download the raw specification at /openapi.json to generate a client, or read the summary below.
Access and authentication
The API comes with the API add-on ($5/month on any paid plan). Send your API key in the Authorization: Bearer header on every request. Keys are created on the API keys page of the dashboard, and the full secret is shown only once.
Core resources
Posts — publish now, schedule, or save drafts, attach media, and target specific connected accounts. Accounts — list OAuth-connected social profiles available for publishing. Media — upload images and video for post attachments. AI — generate platform-native captions from a brief or an existing draft. Webhooks — a signed post.finished event when publishing completes.
Errors and rate limits
Standard HTTP status codes with JSON error bodies. 400 is a validation or platform-rule error, 401 means the key is missing, invalid or revoked (or the API add-on isn't active), 403 means the plan's post allowance is used up, and 429 signals rate limiting with a Retry-After header. Limits: 120 requests/min per key, 300/min per account.
Supported networks
Programmatic scheduling covers Instagram, TikTok, LinkedIn, X, YouTube, Facebook, Threads, Bluesky, Pinterest, Discord, Kick, and Twitch. Reddit posts are created in the Fuxux web app only. Google Business Profile is coming soon and can't be connected or posted to yet. Connect accounts in Fuxux first, then list available targets with the accounts endpoint before scheduling.
