Publishing

Everything you need to publish

One request reaches every network, and you see exactly what happened on each.

Publish once, everywhere

Send a single post and it fans out to every connected network in the format each one expects.

Delivery you can watch and retry

Each platform reports back on its own; ambiguous cases are flagged as delivery_unconfirmed and retried automatically.

Built for workflows and agents

Wire it into n8n, Zapier, and Make, or let an agent post over one OAuth connection.

Know what happened, per platform

Subscribe once and every lifecycle change arrives with a per-network outcome.

Queues, drafts, and timed edits

Recurring slots with jitter and timezone, an eight-week lookahead, and edits until publish.

Build with the Publishing API

Payloads, native formats, per-item delivery status, retries, and queues — it's all in the posts reference.

Publishing questions

Platform coverage, delivery, scheduling, and how publishing works with agents and no-code tools.

01 Which platforms can I publish to?

Instagram, Facebook, TikTok, YouTube, LinkedIn, X, Threads, Pinterest, Bluesky, Telegram, and Google Business, all from the same request.

02 What happens when one platform fails inside a thread?

Each item carries its own delivery status. Ambiguous platform errors are marked delivery_unconfirmed, retries are automatic, and errors are structured as transient or permanent so your pipeline knows what to do.

03 Can I schedule and queue posts?

Yes. Posting queues run recurring weekly slots with jitter and timezone support and an eight-week lookahead, alongside drafts and one-off schedules. Scheduled posts stay editable until five minutes before publish.

04 Do you support AI agents and no-code tools?

There is a hosted MCP server with OAuth discovery for agents, plus official n8n, Zapier, and Make integrations for no-code workflows.

05 Where are the SDKs and the sandbox?

The developer portal has official SDKs, the API Playground, sandbox mode, and the OpenAPI spec. Start from the Social Media API page.
