LinkedIn reference
LinkedIn posts made from your website, without the busywork
For LinkedIn, Postdom turns your website into ready-to-post videos and slideshows in your brand, and posts the ones you approve to LinkedIn. This page links every Postdom guide for LinkedIn: scheduling, the API, video specs and metrics.

LinkedIn guides
Each page below answers one LinkedIn question, with its sources and the date it was checked.
- How to schedule LinkedIn posts
Use LinkedIn’s composer, a dashboard queue, or an agent, and check the result.
- Does LinkedIn have an API?
The Videos API, 3-legged OAuth, and why so little of it can be enforced.
- LinkedIn video specifications
File size, length, format and export guidance for sharing, Pages, API uploads and ads.
- LinkedIn metrics availability
Nine fields, every one unverified, each with its reason.
LinkedIn video specs
LinkedIn publishes different video rules for ordinary sharing, Pages, API uploads and ads. The LinkedIn video specifications page keeps each rule next to the surface and source that states it.
When Postdom makes a video for LinkedIn, you approve it before it goes out.
| Requirement | LinkedIn publishes | Practical export choice |
|---|---|---|
| File size | 75 KB to 5 GB | Stay well below the maximum so uploads and processing finish reliably. |
| Length | Up to 15 minutes; minimum 3 seconds on desktop or 2 seconds in the mobile app | Front-load the point; the allowed maximum is not an engagement recommendation. |
| Resolution | 256x144 to 4096x2304 | Export at the native size of your chosen aspect ratio; do not upscale a small source. |
| Aspect ratio | 1:2.4 to 2.4:1 | Use 16:9, 1:1, 4:5 or 9:16 when you want a familiar feed layout. |
| Frame rate | 10 to 60 FPS | Keep the source frame rate, usually 24, 25 or 30 FPS. |
| Bit rate | 192 Kbps to 30 Mbps | Use enough bitrate to avoid visible blocking without inflating the file. |
| Format | Several containers are accepted by the sharing help page. | MP4 with H.264 video and AAC audio is the compatibility-first choice. |
LinkedIn API
Posting a video through LinkedIn's API means a member-granted access token, the Videos API upload and a post that references the uploaded video. The LinkedIn API explained page walks through each step and permission.
With Postdom you skip that build. You connect your LinkedIn account once and Postdom handles the upload and the post.
Schedule LinkedIn posts
To schedule LinkedIn posts you need three things: the finished post, the profile or Page it goes to, and the time it should go out. Most of the work is making the posts, not setting the time.
Postdom makes the posts for you from your website, and each one waits for your approval. Approve a post and Postdom schedules it to your connected LinkedIn profile or Page. For every option, read how to schedule LinkedIn posts.
What Postdom reports back from LinkedIn
Postdom does not report LinkedIn engagement metrics yet. Every LinkedIn metric field is recorded as unverified, which means missing, not zero. The LinkedIn analytics API page explains why and what LinkedIn itself documents.
