# Buffer's API compared with SkedCast's
URL: https://skedcast.com/developers/guides/buffer-api-alternative

Buffer has a public developer API: a GraphQL API at https://api.buffer.com. Everything on this page about Buffer comes from Buffer's own documentation, and each row names its source. Buffer's pages are the authority for exact operations and limits.

## What Buffer's API covers
Topic | What Buffer's documentation says | Source
Protocol | A GraphQL API with a single endpoint, `https://api.buffer.com`. | https://developers.buffer.com/guides/introduction
Operations | Create and schedule text and image posts, delete posts, create ideas, and retrieve channels, posts and organizations. | https://developers.buffer.com/guides/introduction
Credentials | A personal API key acts for your own Buffer account. An OAuth 2.0 app client (authorization code flow with PKCE) acts for any Buffer user who connects their account. | https://developers.buffer.com/guides/building-apps
Rate limits | Set by your Buffer plan, in 15-minute, 24-hour and 30-day windows. Each app client has its own limits, which grow with the number of users who authorize it. | https://developers.buffer.com/guides/api-limits
Earlier REST API | Buffer publishes a guide for moving from its earlier REST API (`api.bufferapp.com/1/`) to the GraphQL API. | https://developers.buffer.com/guides/rest-migration

## How SkedCast's API differs
SkedCast's API is REST (JSON over HTTPS) with an OpenAPI 3.1 document, API keys with scopes, OAuth 2.1 for third-party apps, signed webhooks and per-platform override fields. It also has connect links, so your own end users can authorize their accounts on a SkedCast-hosted page without a SkedCast login.
API keys and the REST API are included from Studio, and MCP access for AI clients from Solo. See the pricing page for the current plans. The quickstart shows the shape of a first request.

## FAQ
**Q: Can I build an app that other Buffer users connect to?**
A: According to Buffer's documentation, yes: register an app client and use OAuth 2.0 with PKCE, so each user approves your app. A personal API key, by contrast, acts only for your own account. Source: https://developers.buffer.com/guides/building-apps (checked 2026-11-04).

**Q: Which API should I choose?**
A: Choose by what you are building. If you automate your own Buffer account, Buffer's personal API key is built for that. If you need a REST API with an OpenAPI document, connect links for your own end users and webhooks, compare SkedCast's API reference with Buffer's documentation.
