Problem
Content, files and approvals were spread across folders, spreadsheets and messages, with duplication risk and little visibility by channel.

n8n, Meta Graph API and human approval
I built a visual workspace to organize carousels, review captions, select channels and trigger three n8n workflows with independent results for each destination.

SCREENS AND WORKFLOWS
Content, approval and per-channel delivery
The images show the sanitized interface and the published workflow canvases.
AI with supervision
OpenAI, Gemini and Ollama can assist with drafts, but the approved caption remains the main source.
Isolated failures
Results are recorded per channel so that one network does not automatically cancel the others.
What I built
A visual portal, three workflows, API contracts, AI-assisted drafts, destination reservations, `dispatchId`, idempotency, retries and a delivery ledger.
Channel status
- Facebook: multi-image publishing worked on a controlled test Page.
- Instagram: OAuth and publishing were exercised; a later attempt found a limitation in the public media tunnel.
- X: blocked by the test account credit limit.
- LinkedIn: flow prepared but still dependent on credentials and Page access.
What I learned
An integration may work technically and still depend on stable hosting, permissions, quotas and provider policies for continuous operation.
What worked
Facebook and Instagram were exercised in testing. Other channels remain clearly identified as blocked or pending.
Next evolutions
Stable media hosting, independent channel adapters, OAuth renewal, confirmation webhooks and per-destination observability.
This case presents sanitized code, screens and documentation without credentials or internal company content.
