Buffer

Sim's Buffer integration adds 10 Buffer tools to the AI agents you build in Sim's visual workflow builder — you build it all visually. Schedule and publish social media posts across connected channels. Teams often pair Buffer with Linear and Rippling in the same agent.

You can create Post, edit Post, get Posts, get Post, and delete Post with Buffer in Sim, plus 5 more Buffer tools listed on this page. Each runs as a tool inside an AI agent block, so an agent can chain Buffer with services like Linear and Rippling and apply LLM reasoning between steps.

Connecting Buffer takes about five minutes: (1) Create a free account at sim.ai. (2) Create an agent in your workspace. (3) Drag a Buffer block onto the workflow builder. (4) Paste your Buffer API key to authenticate. You can find it in your Buffer account settings. (5) Pick a tool such as "Create Post", wire up its inputs, and click Run, and your agent is live.

Add a Buffer block to your agent and select "Create Post" as the tool. Create a post in Buffer for a channel — add it to the queue, share it immediately, schedule it for a specific time, or save it as a draft, optionally with an image or video attachment. Fill in the required fields. Inputs can reference outputs from earlier steps, such as text generated by an AI block or data fetched from another integration, and you build it all visually.
