Make.com Social Media API: Automate With OmniSocials

If you're running social media content through Make.com, you've probably hit the same wall: every platform wants its own OAuth app, its own API version, its own quirks.

Connecting Instagram means registering a Facebook Developer app, waiting for Business verification, and wiring up three separate API calls just to post a photo. LinkedIn is a separate dance. TikTok requires app review. By the time you've connected four platforms, your Make.com scenario looks like a plate of spaghetti.

There's a better approach. The OmniSocials API wraps all 11 platforms into a single REST endpoint. One API key, one HTTP module in Make.com, and you can publish to Instagram, LinkedIn, Bluesky, Threads, and eight other platforms in one request.

This guide walks through setting up that connection from scratch.

What Is the OmniSocials API?

The OmniSocials API is a unified social media publishing API that handles authentication, media formatting, and platform-specific requirements behind the scenes.

You connect your social accounts once inside the OmniSocials dashboard. After that, every API call uses a single Bearer token. No per-platform OAuth, no app review for each network, no platform-specific payload formats. Send one JSON request to https://api.omnisocials.com/v1/posts and specify which platforms to publish to.

Supported platforms in 2026: Instagram, Facebook, LinkedIn, YouTube, TikTok, X (Twitter), Pinterest, Bluesky, Threads, Mastodon, Google Business Profile.

Pricing is $10/mo (annual) and API access is included. No separate API tier.

Why Not Use Make.com's Native Social Modules?

Make.com has built-in modules for Facebook Pages, Instagram for Business, and LinkedIn. They work, but they come with real limitations.

Each connection is separate. You manage OAuth tokens per platform, per account. A Make.com scenario posting to three platforms means three separate connection setups, three places where auth can expire, three separate module configurations to maintain.

Coverage is inconsistent. Make.com's Instagram module supports basic image posts but not Reels scheduling. LinkedIn's module lags behind API changes. Bluesky, Threads, Mastodon, and Pinterest have no native Make.com modules at all.

The HTTP approach scales better. Configure the OmniSocials API connection once and reuse it across every scenario. Add a new platform? Just change the platforms array in your request body. No new connections, no new modules.

---

Step 1: Get Your OmniSocials API Key

Start at omnisocials.com. Sign up for a free 14-day trial (no credit card required).

Once inside:

1. Click Settings in the left sidebar
2. Navigate to the API tab
3. Click Generate API Key
4. Copy the key and store it somewhere safe (it won't be shown again)

While you're here, connect the social accounts you want to post to. Go to Accounts and connect each platform through the OAuth flow. This is the one time you deal with platform authentication. After this, the API handles everything.

Step 2: Create Your Make.com Scenario

Open Make.com and create a new scenario.

Choose your trigger. The trigger determines what kicks off the social post. Common options:

• Google Sheets — new row added to a content calendar spreadsheet
• Airtable — new record with status "Ready to publish"
• RSS feed — new blog post published, auto-share to social
• Schedule — time-based trigger (post every Monday at 9am)
• Webhook — triggered by another tool or a custom event

For this walkthrough, a Google Sheets trigger works well. Set it to watch for new rows in a spreadsheet where each row contains the post text, media URL, target platforms, and scheduled time.

Step 3: Add the HTTP Make a Request Module

After your trigger, add a new module. Search for HTTP and select Make a Request.

Configure it as follows:

URL:

https://api.omnisocials.com/v1/posts

Method: POST

Headers:

Body type: Raw

Content type: JSON (application/json)

Request content:

{
  "text": "{{1.post_text}}",
  "media": ["{{1.media_url}}"],
  "platforms": ["instagram", "linkedin", "bluesky"],
  "scheduled_at": "{{1.scheduled_at}}"
}

Replace {{1.post_text}}, {{1.media_url}}, and {{1.scheduled_at}} with the mapped fields from your trigger module. In Make.com, click inside each field to open the variable picker and select the matching column from your Google Sheet.

If you want to publish immediately (no scheduling), omit the scheduled_at field entirely.

Note: The platforms array can contain any combination of the 11 supported platforms. Post to one or all of them in the same request.

---

Step 4: Map Your Content Fields

The power of this setup is that the content comes from your data source dynamically.

A minimal Google Sheets content calendar might look like this:

For the platforms field, you can store comma-separated values in Sheets and split them in Make.com using the Split function before passing them to the HTTP module. Or store the platforms as a JSON array string and parse it with Make.com's JSON parsing tools.

The media_url field is optional. Posts without media are text-only.

---

Step 5: Handle the API Response

The OmniSocials API returns a JSON object confirming the post was created:

{
  "data": {
    "id": "post_abc123",
    "status": "scheduled",
    "platforms": {
      "instagram": "queued",
      "linkedin": "queued",
      "bluesky": "queued"
    }
  }
}

In Make.com, parse this response to confirm success. You can:

• Log the post ID back to your Google Sheet (add a Google Sheets > Update Row module after the HTTP call)
• Send a Slack notification when a post is queued successfully
• Route errors to a separate flow if the response status isn't 200

Add a Router module after the HTTP call. One path handles success (status = scheduled), the other handles errors and sends you a notification via email or Slack.

---

Step 6: Test and Activate

Before activating, test the scenario.

Click Run once in Make.com. This executes a single run using live data from your trigger. Check the execution log to confirm:

• The HTTP module returned a 200 status
• The response body contains a post_id
• The post appears in your OmniSocials dashboard under Posts > Scheduled

If the test fails, the most common issues are:

• Wrong API key format (must be Bearer YOUR_API_KEY with a space, not BearerYOUR_API_KEY)
• Invalid scheduled_at format (must be ISO 8601: 2026-04-08T09:00:00Z)
• Platform name typo (instagram not Instagram)

Once the test passes, click Activate and set your schedule.

Doing It the Hard Way: Native Platform APIs vs OmniSocials

For context, here's what connecting Make.com to Instagram natively actually looks like:

1. Create a Facebook Developer account and register an app
2. Apply for the instagram_content_publish permission and wait for app review (can take weeks)
3. Set up the Facebook Graph API OAuth flow in Make.com
4. Handle the media upload step separately (Instagram requires a two-step process: upload media first, then publish)
5. Build a separate Make.com module chain for each additional platform

That's 5 steps for one platform. With OmniSocials, the same result is one HTTP module.

The trade-off is a $10/mo subscription. For most teams running multi-platform content, that's a worthwhile exchange for the hours saved on setup and maintenance.

Common Pitfalls

Expired tokens on platform connections. OAuth tokens for connected social accounts can expire. If a post suddenly fails weeks after setup, check your OmniSocials dashboard for accounts needing reconnection. OmniSocials sends email alerts when this happens.

Make.com operation limits. Make.com's free plan caps at 1,000 operations/month. Each scenario run uses operations equal to the number of modules executed. A 5-module scenario posting daily uses roughly 150 operations/month, well within free limits.

Media URL accessibility. The media field must be a publicly accessible URL. Private CDN links, localhost URLs, or expired signed URLs will fail. Upload images to a public bucket (AWS S3, Cloudflare R2, or Cloudinary) before referencing them in the API call. Alternatively, use the /v1/media/upload endpoint to upload directly to OmniSocials first.

ISO 8601 datetime format. Make.com's date formatting module outputs dates in various formats. Use the formatDate function with YYYY-MM-DDTHH:mm:ssZ to ensure your scheduled_at value is valid.

Platform-specific content rules. OmniSocials handles most formatting differences, but character limits still apply. LinkedIn posts cap at 3,000 characters, X at 280. The API will reject posts that exceed platform limits, so validate content length before it reaches the HTTP module.

Full Example: Auto-Post Blog Articles to Social

Here's a practical scenario: every time you publish a blog post, automatically share it to LinkedIn, Bluesky, and Threads.

Trigger: RSS > Watch RSS Feed items (your blog's RSS feed)

Module 1: Text Parser (format the post caption from the RSS item title and link)

Module 2: HTTP > Make a Request

{
  "text": "New post: {{rss.title}}\n\n{{rss.link}}",
  "platforms": ["linkedin", "bluesky", "threads"]
}

Module 3: Google Sheets > Add Row (log the post ID and timestamp)

That's the entire scenario. New blog post published, three platforms updated automatically, zero manual effort.

Frequently Asked Questions

Does Make.com have a social media API integration?

Make.com has native modules for Facebook, Instagram, and LinkedIn, but they require separate OAuth connections per platform and have limited functionality. The simpler approach is Make.com's HTTP module pointing to the OmniSocials API, which covers 11 platforms through a single connection and API key.

Can I post to Instagram from Make.com?

Yes. Use Make.com's HTTP module to POST to https://api.omnisocials.com/v1/posts with your OmniSocials API key and set platforms to ["instagram"] in the request body. You'll need an Instagram Business or Creator account connected in OmniSocials first.

How much does it cost to automate social media with Make.com?

Make.com's free plan covers 1,000 operations/month, which handles moderate automation volume. OmniSocials costs $10/mo (annual) with API access included. Combined, a multi-platform social automation setup costs $10/mo or less for most teams.

What triggers can I use with Make.com social media automation?

Make.com supports hundreds of triggers including new rows in Google Sheets, new records in Airtable, RSS feed updates, Notion database changes, form submissions, email triggers, and time-based schedules. Any of these can trigger an OmniSocials API call to publish content.

Does OmniSocials have a native Make.com module?

Not yet, but the HTTP module approach works identically. The OmniSocials REST API accepts standard JSON requests, so you configure it once using Make.com's HTTP > Make a Request module and reuse it across all your scenarios without any additional setup.
