Publer API Now Live - Plug The Best Marketing Automation Tool

If you’re searching for a social media API to automate your publishing workflows, integrate content scheduling into your platform, or streamline multi-client management, the Publer API is built for you. Designed for developers, agencies, and marketers who rely on APIs for building scalable systems, Publer delivers flexibility, performance, and ease of use.

If you’re already using Publer to plan, schedule, and manage content across social platforms, imagine taking it a step further by connecting that power directly into your own tools. The Publer API is designed exactly for that.

What is Publer API and what does it do?

Publer’s API is a robust RESTful JSON interface designed for teams building marketing automation tools, social media content planners, or custom dashboards. If you’re building a social media automation platform, a white-label content scheduler, or a workflow engine, Publer helps you get there faster.

The Publer API brings the platform’s publishing, scheduling, and media management capabilities into your own systems. It works through secure, RESTful endpoints and supports:

Publishing and managing posts across multiple social platforms
Bulk scheduling up to 500 posts at once
Uploading, filtering, and organizing social media content
Fetching workspaces, accounts and users

It’s built for developers and marketers who want seamless social automation without relying on manual dashboards.

Supported Social Networks & Content

Just like within Publer’s platform, with the API key you can publish and manage content across 13 major platforms: Facebook, Instagram, Twitter/X, LinkedIn, Pinterest, YouTube, TikTok, Google Business Profile, WordPress, Telegram, Mastodon, Threads, and Bluesky.

The API supports:

Status updates
Images, video, gifs
Reels and carousels
Stories
Polls
PDFs and documents
Links and articles
Text Posts with background
Multi-link posts (Facebook Carousels)
Pinterest pins with a link URL

Key Capabilities

With the API come all the features you need to build a system that works for you and your social media management workflow.

1. Content Publishing & Bulk Scheduling

With the Publer API, you can create, draft, schedule, auto-schedule, or instantly publish content across multiple social media accounts, customized per platform. The API supports one-time posts, recurring schedules, and recycled content. Each action returns a job ID so you can track post status easily.

You can also bulk schedule up to 500 posts in a single API request. Each post in the batch can have its own text, media, platform, and schedule, making large-scale planning faster and more organized. Bulk scheduling supports all post types across every network Publer supports.

Need to make changes? You can modify or delete posts even after they’re published, depending on the rules of each platform.

2. Media Management

Use the Media API to upload files directly or via URL. Once uploaded, you receive media IDs that can be reused across posts. Filter assets by type, label, usage status, or source. You can even retrieve albums, boards, or watermarks.

Supported media formats include JPG, PNG, GIF, WEBP, MP4, MOV, PDF, and more. Check our limitations for more information.

3. Listing Workspaces, Accounts and User Details

Each API request includes the workspace ID, ensuring all actions are scoped correctly. Workspaces help you keep tabs of teams, clients, accounts, all under your own system.

You can retrieve profile info, subscription data, and access permissions for authenticated users, ensuring secure multi-team collaboration.

With Publer API You Can Go Beyond Basics

In addition to post scheduling, media uploads, and analytics, the Publer API supports key features designed to reinforce your brand and maintain consistency across social platforms.

Branded Signatures

Automatically add a signature block to your posts, like a call-to-action, branded tagline, or your info. Signatures ensure your content maintains a consistent tone and branding across networks. You can create multiple signatures per account and choose which one to apply when scheduling posts.

Watermarking

Protect your visuals and reinforce your brand identity with automated watermarks. Upload your logo or brand marks and let Publer apply it automatically to all image or video content. This saves editing time and helps protect your creative assets online.

Post Callbacks & Follow-up Actions

Go beyond publishing with powerful follow-up automations. The Publer API supports post callbacks, configurable actions that trigger after your post is published or scheduled:

AutoShare: Instantly share a published post to other connected social accounts
Follow-up Comments: Schedule a comment to be added after the original post goes live
Auto-Delete: Automatically remove a post from selected networks after a set time

You can use these features for time-sensitive content, multi-step campaigns, and maintaining clean profiles.

How to Get Started With Publer API

Getting started with the Publer API is straightforward, especially if you already know what you want to build or integrate.

Step 1: Generate an API Key
Sign in to your Publer account and ensure you have Ambassador or Enterprise access. Navigate to Settings → Access & Login → API Keys. Click Create API Key, enter a descriptive name, and choose the scopes you need (workspaces, posts, accounts, users, media, job_status). Click Create and make sure to copy the key as it won’t be shown again.

Step 2: List Your Workspaces
Before making other API calls, use the endpoint to list your workspaces. You’ll need your workspace ID for almost every action as it ensures that your requests are sent to the correct brand, team, or client environment.

Step 3: List Social Accounts
Retrieve all connected social media accounts within your workspace. This gives you the account IDs needed to publish posts to the right places.

Step 4: Upload Media (Optional)
If your post includes images, videos, or PDFs, you’ll need to upload them first using the Media API. You’ll get back media IDs, which can be referenced in post creation.

Step 5: Schedule or Publish a Post
Use the Posts API to create a scheduled post, draft, recurring post, or publish something instantly. You can even batch multiple posts into a single API call.

Step 6: Track Status
Every action you take, like publishing or scheduling, returns a job ID. Use this ID to check status, or troubleshoot errors after publishing.
