Facebook via Buffer

BeeGentic writes the post and hands it to Buffer, and Buffer publishes it to your Facebook Page on your schedule or right away. Real result included.

What you'll build: you type a topic, an AI writes the post, and BeeGentic sends it to Buffer. Buffer then publishes it to your Facebook Page. Three blocks: Start → Agent → Buffer. About 7 minutes, including the Buffer setup.

What BeeGentic can do with BufferAll tools →

Posts to: Any channel connected in your Buffer account · Connect with: Buffer API key · Block: Buffer

Don't use Buffer? You don't need it. BeeGentic can post to your Page directly: see Publish to a Facebook Page. Buffer is for teams that already plan their posts in Buffer.

Part 2: Build the workflow

Create the workflow and the Agent

+ New workflow → name it Agent to Buffer. Add Toolbar → Agent, choose gpt-5-mini with {{OPENAI_API_KEY}}, and in Messages type:

Write a Facebook post (max 60 words) announcing: <start.input>. Friendly and clear, one emoji, end with 2 relevant hashtags. Return only the post text.

It's the same Agent as in the direct guide. Prefer ChatterMate? Use the ChatterMate block instead and reference <chattermate.content> below.

Troubleshooting

Problem	Fix
`Invalid post: Facebook posts require a type`	Update to the latest BeeGentic (it now sends Feed post automatically), or set Post Type under Show additional fields.
Authentication or invalid-key error	The key was regenerated or mistyped. Create a new key and update the `BUFFER_API_KEY` secret.
Channel not found	Check the Channel ID with Get Channels. The key must belong to the Buffer organization that owns the channel.
Post is in Buffer but not on Facebook	It's waiting in the Queue (Add to queue). Use Share now, or check the channel's posting times in Buffer. If Buffer shows a reconnect warning, reconnect the Page in Buffer.
`429` / rate limit	You hit Buffer's API limit. Wait 15 minutes, or upgrade your Buffer plan.
