Post to Multiple Instagram Accounts the Smart Way

Marketing agencies, business owners, and social media managers often manage 2 or more Instagram accounts and need to publish content consistently across all of them. However, switching between accounts manually or using multiple social media management tools can quickly become time-consuming, repetitive, and difficult to manage.

The smarter approach is to use a social media management tool that lets you manage and publish content to multiple Instagram accounts from one place. In this guide, you'll learn why you need a social media management tool, which types of Instagram content you can publish, and how to post to 2 or more Instagram accounts effectively using the Zernio dashboard, API, and AI agents through its MCP server.

Why Post to Multiple Instagram Accounts?

Posting to multiple Instagram accounts from one social media platform can save time, simplify content management, and make it easier to maintain a consistent publishing schedule. This is particularly useful for developers integrating social media features, agencies managing client accounts, and businesses operating multiple Instagram profiles.

Some of the reasons why you might need to post to multiple Instagram accounts at once include:

1. You Build a Product that Integrates Instagram Posting

If you're building a SaaS product or marketing tool, you may want to allow customers to publish content to their Instagram accounts directly from your product. An Instagram API integration lets you add content publishing features to your application, enabling users to manage their social media accounts without leaving your platform.

2. You Manage Instagram Accounts for Multiple Clients

Social media managers and marketing agencies often manage Instagram accounts for several clients. Each client may have their own content calendar, publishing schedule, and account credentials. You might want to schedule and publish content for multiple clients without repeatedly switching between Instagram profiles.

3. You Manage a Business with Multiple Accounts for Different Locations

Businesses with multiple locations, brands, products, or audiences may operate separate Instagram accounts for each one. For example, a restaurant chain might have an account for each location, while a company may maintain separate profiles for different markets.

4. You Need to Publish the Same Content to Multiple Accounts

You may need to publish the same announcement, promotion, campaign, or other content across two or more Instagram accounts. This is useful when different accounts share similar audiences, promote the same campaign, or represent different parts of the same organisation.

5. You Want to Cross-Post Content to Other Social Platforms

Instagram may be only one part of a broader social media strategy. You may also want to publish the same content to multiple social media platforms, such as Facebook, LinkedIn, X (Twitter), or TikTok. A unified social media management tool can help you manage these posts from one place and adapt the content to each platform's requirements.

Types of Instagram Content You Can Post

Instagram supports several content formats that you can use to engage your audience, promote your products or services, and share updates. When posting to multiple Instagram accounts, the content format you choose may depend on your campaign, audience, and publishing goals.

Here are the three main types of Instagram content you can publish:

Instagram Reels

Reels are short-form vertical videos designed for engaging and discoverable content on Instagram. You can use them to share product demonstrations, tutorials, behind-the-scenes content, announcements, or other video-based content. If you manage multiple Instagram accounts, you can publish or schedule Reels across the accounts that are relevant to your campaign.

Instagram Stories

Instagram Stories are temporary posts that appear in users' feeds for 24 hours. They are useful for sharing timely updates, promotions, announcements, polls, and other content that encourages quick engagement. For businesses managing multiple accounts, Stories can help you share account-specific updates.

Instagram Image and Video Posts

Instagram feed posts allow you to publish images and videos directly to your profile. You can use them for product photos, promotional graphics, educational content, announcements, and other evergreen content.

Instagram Reels vs Stories vs Posts

Instagram Reels, Stories, and feed posts serve different purposes and have different media requirements. Understanding these differences can help you choose the right format for your content and ensure your media meets Instagram's publishing requirements.

The table below compares the main differences between Instagram feed posts, Reels, and Stories.

How to Post to Multiple Instagram Accounts with Zernio

Zernio lets you post to multiple Instagram accounts from its dashboard, programmatically through its API, or automatically using AI agents. In this section, you'll learn how to schedule and publish content across 2 or more Instagram accounts using the Zernio dashboard, API, and MCP server integration.

Post to Instagram with the Zernio Dashboard

Step 1: Connect your Instagram accounts to Zernio

Log in to your Zernio account, then navigate to Connections in the sidebar to connect your first Instagram account. You can connect your Instagram account through Facebook or directly through Instagram.

To connect additional Instagram accounts, open the All Profiles dropdown and create a new social profile. You can create multiple social profiles and connect the social media accounts you need to manage within each profile. A social profile in Zernio is a collection of the 16 supported social media platforms.

Step 2: Schedule and publish posts from the dashboard

Select Posts from the sidebar and click Create Post.

In the Create Post section, select the Instagram accounts you want to publish to, then upload an image or video and choose the content type, such as Feed, Story, Reel, or Carousel. You can also add a caption, tag up to 3 collaborators, and leave the first comment on the post before scheduling or publishing it.

Post to Instagram via API with Zernio

If you're building a SaaS application or integrating social media posting into your applications, you can use the Zernio API to schedule and publish social media posts programmatically. The unified social media API lets you publish to multiple social media platforms using the same request format and authentication method.

Step 1: Create a Zernio API key

Select API Keys from the sidebar menu to create a new API key and save it somewhere on your computer. Before making API requests, ensure that your Instagram social media accounts are already connected to Zernio.

Step 2: Schedule and publish posts using the Zernio API

To publish Instagram Posts, Reels, Stories, or Carousels to multiple Instagram accounts, send a POST request to the Zernio Posts API endpoint:

curl -X POST https://zernio.com/api/v1/posts \
  -H "Authorization: Bearer $ZERNIO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "Hello from Zernio API!",
    "mediaItems": [
      { "type": "image", "url": "https://cdn.example.com/photo.jpg" }
    ],
    "platforms": [
      {
        "platform": "instagram",
        "accountId": "69c784cb**********",
        "platformSpecificData": { "contentType": "story" }
      },
      {
        "platform": "instagram",
        "accountId": "6a7aa5c5d0********"
      }
    ],
    "publishNow": true
  }'

The request authenticates using your Zernio API key, then sends the post to the Instagram accounts specified by their accountId values. You can also replace "publishNow": true with a scheduledFor timestamp (for example, "scheduledFor": "2026-03-15T10:00:00Z" with "timezone": "America/New_York") to schedule the post for later.

Get your Instagram account ID by clicking the Copy icon next to the connected Instagram account in your Zernio dashboard.

The type of Instagram content Zernio publishes depends on the media you provide and the contentType settings you specify. Here are the rules for publishing Feed Posts, Stories, Reels, and Carousels:

1. Instagram feed posts: You do not need to specify a contentType when publishing a single image or video with a supported aspect ratio of 4:5 (portrait), 1:1 (square), or 1.91:1 (landscape). Zernio automatically treats the content as a feed post.
2. Instagram Reels: A single video with a 9:16 aspect ratio and a maximum duration of 90 seconds is automatically treated as a Reel when no contentType is specified. To share the Reel to the Instagram feed, add shareToFeed: true inside the platformSpecificData object.
3. Instagram Story: Set contentType to "story" inside the platformSpecificData object to publish the media as an Instagram Story.
4. Instagram carousel: Add up to 10 images or videos with the same aspect ratio to publish them as a carousel.

Zernio also provides official SDKs for Node.js, Python, Go, Ruby, Java, PHP, .NET, and Rust, allowing you to integrate the API into your application using your preferred programming language, without making HTTP requests to the API endpoints directly.

Post to Instagram with AI agents and Zernio MCP

If you use Claude or another MCP-compatible AI assistant, you can connect it to the hosted Zernio MCP server to schedule and publish posts, retrieve scheduled content, post analytics, and manage your social media accounts using natural language.

Step 1. Download and install Claude Desktop, Claude Code, or Cowork on your computer. Click the + sign, then select Add connector > Add custom connector.

Step 2. Enter the MCP server URL into the input field to connect Claude to the Zernio API.

Step 3. Once connected, you can schedule posts and view, manage, or retrieve your scheduled and published posts directly from the Claude interface.
