Buffer's API lets you publish and manage content across 10 social platforms through a single endpoint. Connect it to AI assistants, no-code automation tools, or build full custom integrations. Ships with an MCP server, pre-built automation templates, a CLI, and an interactive API explorer. Available on every Buffer plan, including Free.
I’ve built a TRMNL plugin with the Buffer API; it shows my queue counts, along with my next scheduled posts and previously sent posts, on an e-ink display sitting on my desk. I’ll make this available for installation soon.
The API is straightforward to work with, and AI tooling makes prototyping extremely quick. If you're building anything that touches social media, this is worth a look.
And if additional parameters need to be specified during publishing (for example, privacy settings), can those also be managed?
Hi guys ! Working on a competing launch today (Pancake), but I have to say that I love Buffer and that this is a really cool release that we'll probably use at Pancake, so best of luck for today !! Love from the Pancake crew 😍
We’ve hit this exact problem internally. Every platform behaves just differently enough that “post everywhere” becomes messy really fast once automations enter the picture.
The MCP + API combo here is smart. Are most teams using Buffer API as infrastructure inside agents/workflows now, or still mainly for traditional scheduling flows?
As a fellow bootstrapped company, it's always a pleasure to see Buffer being back over here 🔥 I'm curious, is the next step the Buffer MCP?
👋 Hey everyone, Mike here, another one of the makers on the Buffer team.
A bit more about the API:
Buffer's API lets you connect Buffer to the tools you already use, whether that's an AI agent, a no-code automation tool, or your own stack. You can publish, schedule, and manage your social presence from wherever you already work.
Under the hood: GraphQL API, MCP server, CLI, managed OAuth, pre-built workflow templates with no-code tools like Zapier and n8n, and an interactive API explorer.
A few more examples of what people have been building with it:
An automated weekly reporting system across 77 social channels in 10 languages, built with n8n by someone who isn't a developer.
A Friday morning Slack bot that recaps what was posted, what's scheduled, and what's missing. Plus a full LinkedIn content library and analyzer on Lovable, both built entirely through conversation with AI.
A power-user layer on top of Buffer with thread splitting, a content calendar with planning notes, and a snippet library.
A Substack growth platform for creators, with Buffer handling social distribution automatically.
It's also available on every Buffer plan, including Free.
Let us know if you have any questions and excited to see what other folks build with it!
Most social publishing APIs fall apart on edge cases like platform-specific media constraints, rate limit variance across accounts, or diff post formats per network. Curious how the Buffer API handles those inconsistencies at the normalization layer. Do you expose a unified schema and translate per-platform, or does the caller still need to know what Twitter vs LinkedIn expects?

Who hunted Buffer API?
Buffer API was hunted by Andrew Yates. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
