Buffer API

The Buffer API is a GraphQL interface that lets you connect your own tools and workflows to your Buffer account. It's designed so you can automate common tasks and build custom integrations on top of Buffer's publishing and planning features.

With the current Buffer API, you can perform actions against your own Buffer account and organization. Today, this includes: Creating, fetching, and deleting posts in your queues. Creating ideas in your Ideas library. Retrieving your accounts, organization, and connected channels. In practice, this means you can, for example: Auto-create posts from your CMS or internal tools. Pull scheduled content into your own dashboards. Sync channel and organization details into internal reporting systems.

To get started you'll need a Buffer account and an API key. Once you're logged in: Go to API in your Buffer account settings . Create a personal API key (recommended for individual use) or an App Client Make your first API request Our developer portal includes example queries to help you fetch your account, organization, channels, and posts.

Access to the API is available on all current Buffer plans, including Free, with different limits depending on your plan. Each plan includes a specific number of API keys and app clients, plus rate limits over 15‑minute, daily, and 30‑day windows. You can see your plan and upgrade options any time in your billing settings .

The number of API keys you can create depends on your Buffer plan. Free: 1 API key and 1 app client. Essentials: 3 API keys and 3 app clients. Team: 5 API keys and 5 app clients. You can manage and rotate keys from your API settings in Buffer.

Rate limits are applied per client and vary by plan. For each API key, the current limits are: 15‑minute limit: 100 requests on all plans. 24‑hour limit: 100 (Free), 250 (Essentials), 500 (Team) requests. 30‑day limit: 3,000 (Free), 7,500 (Essentials), 15,000 (Team) requests. If you exceed a limit, the API will return an error and you'll need to wait until usage falls back under the allowed window.

Yes. If you are building a partner integration or expect higher usage, you can reach out to the Buffer team to request increased limits. Please reach out to developersupport@buffer.com to discuss options.

Yes, support is available for developers using the API. You can: Use the guides and reference on the Buffer developer portal . Interact with our chat support on both our developer portal and from within Buffer's interface. Contact developer support via developersupport@buffer.com .

We're continuing to expand what you can do with the Buffer API, including plans to add support for analytics and community features for personal use cases. This will make it easier to bring more of your Buffer insights and engagement workflows into your own tools.

To create an API key or App Client and to view your API limits, you'll need to be an organization owner in your Buffer account. These will only be visible to you and not your teammates. We will be looking to extend permissions for this in the future.
