Telegram is the easiest network to publish to by API: no app review, no fee, one token from BotFather. This guide is current to Bot API 10.3 and covers creating the bot, finding a channel chat ID, sendMessage with HTML, photos and albums, the new rich messages, limits, scheduling, and the errors you will meet, with curl, Node, and Python.

Meta lists dozens of Instagram publishing error codes. We pulled every failed Instagram publish from PostZen's production database since June 2026 and found five Meta codes plus one of our own, one image behind two thirds of the failures, and a gap in our own retry logging. This guide covers every code, what our data says about each one, and a classifier in Node and Python.

TikTok spreads its Content Posting API error codes across six reference pages and a general error page, and some failures only show up later as a fail_reason on a request that returned HTTP 200. This guide puts every code in one table, explains what each one means and whether a retry helps, and shows the handling we run in production at PostZen.

Google changed the YouTube Data API quota model twice between December 2025 and June 2026, and guides written before then still quote a 1,600-unit upload cost that no longer applies. This guide gives the current three-bucket allocation, per-method costs, capacity math, every quota error and its look-alikes, a quota-aware helper in Node and Python, and the audit that unlocks a quota increase.

Sprout Social gates its API to the Advanced plan, and the publishing endpoint writes nothing but drafts, yet it is the supported way to get Sprout's reporting data into a warehouse or to hand finished content to a social team. This guide covers the plan and permission gates, API tokens and OAuth, every endpoint and its limits, a complete draft-creation flow in Node and Python, the ChatGPT-only MCP server, and the Developer Terms. It closes with an honest comparison against a developer-first API for products that need to publish.

Hootsuite has run a free public REST API since 2016, and in 2026 it added an Analytics API and four MCP servers as part of a push to go headless. This guide covers how access works, what the endpoints do, the rate limits and real costs, what the MCP servers can and cannot change, and when a developer-first API is the better fit.

Buffer reopened its public API on May 27, 2026 as a GraphQL endpoint with an MCP server, a CLI, and OAuth app clients, and many guides online still describe the old REST API or call the API closed. This is the current picture: what the Buffer API can do, what each plan allows, how to get a key and make the first request, and where the gaps are. It ends with an honest comparison against a developer-first API for the products Buffer was not built for.

Every platform has an analytics API, and no two agree on what a view is. This guide maps what Instagram, Facebook, X, YouTube, TikTok, LinkedIn, Pinterest, Threads, Bluesky, and Telegram expose through their official APIs, who is allowed to read it, and how far back it goes, with working code for the YouTube Analytics API and one unified call that covers eight of them.

People search for an Instagram API key, but Instagram does not issue one. What you need is an access token: a one-hour short-lived token from OAuth, exchanged for a 60-day long-lived token that you refresh before it expires. This guide walks through the Meta app setup, the App Dashboard shortcut for accounts you own, the full Business Login flow with working Node and Python code, and the refresh job that keeps tokens alive.

TikTok's built-in scheduler is free but narrow: web only, a Business Account, 15 minutes to 10 days ahead, and no editing once scheduled. TikTok Shop creators get 30 days for shoppable videos. Past that you need a scheduler with a queue and CSV import, or the Content Posting API through a service that holds the post. This guide covers all four with the limits from TikTok's own pages, working code, and a decision table.

LinkedIn schedules posts for free, up to three months ahead, on profiles and Pages. Pages cannot schedule polls, multi-photo posts, or reshares, and nothing native schedules a first comment or fills a weekly queue. This guide covers the built-in scheduler with the exact limits from LinkedIn's help pages, the queue and CSV route, and the API route with Node and Python code, plus a decision table.
Jesse EisenbartSeptember 25, 2026
Instagram lets you schedule posts for free, with limits: 25 a day, 30 days ahead, public accounts only, and no Stories or collaborator posts. Meta Business Suite widens that a little. Past that you need a scheduler with a queue and a CSV import, or the API. This guide walks through all four routes with the exact limits from Meta's help pages, working code, and a decision table at the end.

A white label social media API lets an agency sell publishing, scheduling, and engagement under its own brand while someone else maintains the platform integrations. The seven APIs in this guide handle the white-label part in very different ways: branded hosted pages, fully headless flows, or your own OAuth app on the consent screen. We compared them with homepage and pricing screenshots captured on the same day, real prices from each pricing page, and two worked agency bills.

Searching for Instagram API pricing returns scrapers with monthly plans and guides that never answer the question. The answer: Meta charges nothing for the Instagram API. What you pay is time, in business verification, app review with a screencast, media hosting, and rate-limit handling. This short guide lists those costs, the limits that actually apply, and the point at which a unified API is cheaper than the engineering.

A social media posting API publishes now. A social media scheduling API holds a post, publishes it at the right moment on every network, and tells you what happened. Only two of the ten major platforms offer scheduling in their own APIs, so everything else is built by the layer above them. This guide explains that layer: the request, the storage and claim step that guarantees a post never publishes twice, queues with weekly slots, time-zone semantics, failure handling, and the differences between the scheduling APIs on the market.

An auto poster for social media is any system that publishes without a person pressing the button: an RSS feed watched every fifteen minutes, a CMS that fires a webhook on publish, a cron job that drains a queue, or an AI agent that decides what to post. This guide compares the four routes, gives a working recipe for each in Node, Python, and a plain prompt, and lists the platform rules (image-only Instagram, X's per-post fees and duplicate-content policy, Pages-only Facebook) that decide whether an auto-poster survives its first week.

Someone comments "GUIDE" on your Reel and 40 seconds later has the link in their DMs, with a public "sent!" under their comment. This guide explains the Meta mechanism behind that, walks through setting it up in the PostZen dashboard with a video, covers keyword modes, story replies, follow gates, and delays, shows the complete API request, and finishes with how an AI agent can create the automation from a prompt.

Managing multiple social media accounts breaks in predictable ways: five logins on one phone, a shared password that violates every platform's terms, a token that expired on a Sunday, and a client account nobody can reconnect. This guide covers what each platform allows natively, the roles that replace password sharing, the token lifetimes behind every reconnect prompt, and how to structure accounts for three very different situations.

Manychat charges by active contact, cut its free plan to 25 contacts in March 2026, and has no API for creating automations. If any of those is your problem, this guide compares seven alternatives for Instagram comment-to-DM automation, including one you can run entirely from an API key or an AI agent, and explains the Meta rules every one of them lives under.

The belief that scheduling a post, or publishing it through a third-party tool, quietly cuts its reach is one of the most durable myths in social media. This guide checks it against every platform's own ranking explainer, the experiments that actually compared scheduled and native posts, and the mechanics of API publishing, then lists the things that genuinely lower reach so you can fix those instead.

Pinterest API v5 is one of the easier social APIs to get into and one of the easier ones to get wrong: pins made under Trial access are invisible to everyone but you, Create Pin needs four scopes not one, video needs a four-step upload with a mandatory cover, and the refresh token rules changed in September 2025. This guide covers the whole path from app registration to a published pin, with the limits that matter and what the Standard access review actually asked us for.

People search for LinkedIn API pricing expecting a rate card and find none, because LinkedIn does not charge for its API. What it does instead is gate every product behind an application, tier the ones that matter, and cap the Development tier at 100 calls per member a day. This guide lays out the whole access-and-cost picture: which products are self-serve, what Community Management API review asks for, how many API calls one post really takes, how long tokens last, what versioning costs you in maintenance, and where money actually changes hands.

The Facebook API for Pages is one of the oldest social APIs and one of the most confusing: three kinds of tokens, seven permissions, two access levels, and four publishing endpoints. This guide walks through the whole path from creating a Business app to publishing text, links, photos, videos, and Reels on a Page, with the current limits, the app review process, and what changed in Graph API v22 through v26.

Posting to multiple social media platforms at once sounds like one button, but the platforms disagree on text limits, link handling, media formats, and required fields. This guide compares native cross-posting, all-in-one scheduling apps, and the API route, then shows one request that publishes to ten networks with per-platform overrides and webhooks for partial failures.

X shows a view count under every post and an impressions count in analytics, and they are the same number measured the same way. This guide explains what each metric counts, what engagement rate means, why nobody can see who viewed a profile, and exactly which fields the API returns, for whom, and at what price.

Bluesky is the only major network with no app review, no fee, and no scopes to request. This guide covers how the AT Protocol works, app passwords and OAuth, building a post record with facets and embeds in Node and Python, reply gating, rate limits, and the lessons from shipping PostZen’s first non-OAuth platform.
Jesse EisenbartSeptember 08, 2026
Meta’s Threads API is the simplest of its publishing APIs: text posts are allowed, review is lighter, and the limits are published. This guide covers auth, permissions, publishing with Node and Python, media specs, quotas, replies, polls, insights, and the errors you will see.
