Platforms — one API

Native LinkedIn API · the actual cost

What you'd build and maintain yourself

Every item below is real friction the native LinkedIn API hands you. PostPulse handles all of them.

Partner approval gate

LinkedIn Marketing Developer Platform (MDP) requires a partner application approval

PostPulse holds the partner access — you inherit it.

Restricted APIs

Community Management API is restricted — most developers cannot access it without a formal partnership

Post to Pages and profiles with no partnership needed.

60-day token expiry

Token refresh logic is complex: access tokens expire after 60 days requiring user re-auth

PostPulse manages refresh and re-auth for every user.

Org vs member endpoints

Organization vs. member posting uses completely different API endpoints and OAuth scopes

One endpoint posts to both — scopes mapped for you.

Multi-step video upload

Video upload requires a separate "upload registration" step before the actual upload

Pass a URL or file; PostPulse runs the upload handshake.

Minutes to your first post

Schedule a LinkedIn post in two API calls

Import your media, then schedule the post with your LinkedIn settings. PostPulse does the rest.

# Step 1: Import media from a public URL
curl -X POST https://api.post-pulse.com/v1/media/upload/import \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{ "url": "https://your-cdn.com/media/video.mp4" }'

# Response: { "path": "uuid/video.mp4" }

# Step 2: Schedule a post using the publications array
curl -X POST https://api.post-pulse.com/v1/posts \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "scheduledTime": "2026-06-01T10:00:00Z",
    "isDraft": false,
    "publications": [
      {
        "socialMediaAccountId": 123,
        "platformSettings": { "type": "LINKEDIN", "visibility": "PUBLIC" },
        "posts": [
          {
            "content": "Check out our latest content! #developer #api",
            "attachmentPaths": ["uuid/video.mp4"]
          }
        ]
      }
    ]
  }'

What you ship on day one

What you can build with the LinkedIn API

Every capability maps to a real field in the API. Click through for the exact request shape.

LinkedIn Video Scheduling

Schedule video posts to publish at a specific future date and time across multiple platforms.

LinkedIn Image Posting

Post single images or photo collections to social media platforms via REST API.

LinkedIn Carousel

LinkedIn Scheduling

Schedule any post type — text, image, video, or carousel — to publish at a precise future timestamp.

LinkedIn Auto-Publish

Trigger immediate publication to social media platforms from your backend or automation workflow.

LinkedIn Media Upload

Upload images and videos via direct binary upload, presigned URL, or remote URL import — then reference the media path in attachmentPaths.

LinkedIn Privacy Controls

Set per-post privacy levels, audience visibility, and content controls programmatically.

LinkedIn Webhooks

Receive real-time webhook events for post completion, failure, and media import status across all platforms.

DIY vs PostPulse

The same LinkedIn integration, two timelines

Both columns assume you know your stack. Only one has you doing undifferentiated platform plumbing.

DIY · native LinkedIn API

Register a developer app and configure OAuth redirect URLs
Implement the OAuth flow plus token refresh and rotation
Build the media-upload and publish flow around LinkedIn's quirks
Clear access requirements — review, quota, or partner approval where required
Build scheduling, retries, and failure alerting yourself
Keep up with API version changes — forever

PostPulse

James Mccarthy

I use PostPulse with an AI agent via their MCP server. My agent literally posts to social media on its own now. Didn’t expect that to work as smoothly as it did.

Antonio Widera

$5/month for what would otherwise require a full backend engineer to maintain? Easy yes. The REST API is clean and well-documented too, which is rare.

Shawn Padilla

Tried to get TikTok API access myself. Three weeks, two rejections. Switched to PostPulse and was posting to TikTok the same day. Wish I hadn’t wasted that time.

Karen Rivers

I’m a Make.com power user and needed to post to 5 platforms from one scenario. The native PostPulse app for Make connected everything in one afternoon. Would’ve taken me weeks to do manually.

Douglas Finch

I built an n8n automation for a client and needed to add social publishing. The official PostPulse n8n node was literally drag and drop. No headache.

Andrea Scott

Saved me months of dev work. I was about to start integrating Instagram and TikTok APIs separately — then I found out Meta’s app review alone can take months. PostPulse just handled all of that. Shipped social posting in under a week.

William Dirks

The most flexible pricing model on the market!

I'm building an AI content factory as a side hustle. I'm still in the experimentation phase, so I don't have the budget for expensive tools — but I also needed to get everything up and running quickly, so I integrated with a ready-to-go API instead. PostPulse offers a flexible pay-as-you-go model that let me experiment first without commitment — and now that we have stable traffic, I’ve switched to their $5/month subscription.

Best support on the market — the founder personally emailed me when I hit a client error and walked me through the fix.

We optimized the posting to 20 twitter accounts. It was a problem to manage such a number, but through the platform everything works out perfectly. Very convenient dashboard for tracking errors. Great product.
