API Quickstart

Get Started with Blotato API

The Blotato API allows you to:

• publish and schedule posts directly to social media platforms

• supports text, image, videos, reels, slideshows, carousels, threads, and stories

• create images, videos, slideshows, and carousels programmatically via templates

It is limited to paying subscribers in order to reduce spam and service abuse, keeping Blotato's integration in good standing with the social platforms.

Plans That Include API

Plan	API Access
Free Trial	No
Starter	Yes
Creator	Yes
Agency	Yes

API access is included on every paid plan. Generating an API key from Settings > API immediately ends a free trial and activates your paid Starter subscription.

Base URLs

Blotato has two base URLs. Use the one that matches your integration:

Integration	Base URL
REST API (direct HTTP, n8n, Make)	https://backend.blotato.com/v2
MCP Server (Claude Code, Claude Cowork, Claude Desktop, Cursor, Antigravity)	https://mcp.blotato.com/mcp

api.blotato.com is not a valid base URL. If your AI tool reports a DNS error for api.blotato.com, it guessed wrong. Use one of the two URLs above.

API Dashboard (for debugging): https://my.blotato.com/api-dashboard

FIX MY AUTOMATION (n8n only): On a failed n8n request in the API Dashboard, click the green FIX MY AUTOMATION button and Blotato AI will attempt to fix your n8n workflow automatically.

Raw REST API Calls - Examples

Authentication

To authenticate API requests, include your Blotato API key in the request headers.

Authentication Header

blotato-api-key: YOUR_API_KEY

Requests without a valid API key will be rejected and 401 error will be returned.

Step 0: Get Your Account IDs

Before publishing, fetch your connected accounts to get the accountId:

GET https://backend.blotato.com/v2/users/me/accounts HTTP/1.1
blotato-api-key: YOUR_API_KEY

Use the id from the response as your accountId. For Facebook and LinkedIn, also fetch subaccounts to get pageId. See Accounts reference for details.

Post to a Platform Immediately

POST https://backend.blotato.com/v2/posts HTTP/1.1
Content-Type: application/json
blotato-api-key: YOUR_API_KEY

{
  "post": {
    "accountId": "98432",
    "content": {
      "text": "Hello, world!",
      "mediaUrls": [],
      "platform": "twitter"
    },
    "target": {
      "targetType": "twitter"
    }
  }
}

Post at a Scheduled Time

POST https://backend.blotato.com/v2/posts HTTP/1.1
Content-Type: application/json
blotato-api-key: YOUR_API_KEY

{
  "post": {
    "accountId": "98432",
    "content": {
      "text": "Scheduled post example",
      "mediaUrls": [],
      "platform": "facebook"
    },
    "target": {
      "targetType": "facebook",
      "pageId": "987654321"
    }
  },
  "scheduledTime": "2025-03-10T15:30:00Z"
}

To schedule at the user's next available calendar slot instead of a specific time, replace scheduledTime with useNextFreeSlot: true. Both are top-level fields, not inside post. See Publish Post for all scheduling options.

Post a Twitter Thread with Multiple Posts

POST https://backend.blotato.com/v2/posts HTTP/1.1
Content-Type: application/json
blotato-api-key: YOUR_API_KEY

{
  "post": {
    "accountId": "98432",
    "content": {
      "text": "This is the first tweet in the thread.",
      "mediaUrls": [],
      "platform": "twitter",
      "additionalPosts": [
        {
          "text": "Here's the second tweet, adding more info.",
          "mediaUrls": []
        },
        {
          "text": "And here's the third tweet to conclude!",
          "mediaUrls": []
        }
      ]
    },
    "target": {
      "targetType": "twitter"
    }
  }
}

Attach Media to Post (images and videos)

Pass any publicly accessible image/video URL into the mediaUrls parameter. No upload step required. Blotato handles the media transfer.

For local files without a public URL, use the Presigned Upload endpoint to upload directly to Blotato. No Google Drive or S3 needed.

POST https://backend.blotato.com/v2/posts HTTP/1.1
Content-Type: application/json
blotato-api-key: YOUR_API_KEY

{
  "post": {
    "accountId": "98432",
    "content": {
      "text": "Check out this image!",
      "mediaUrls": [
        "https://example.com/image.jpg"
      ],
      "platform": "instagram"
    },
    "target": {
      "targetType": "instagram"
    }
  }
}

The optional Upload Media endpoint is still available if you need to host media on Blotato's servers. See Upload Media.
