If you already automate
Same posting, from your workflow
The New post screen is how most people publish. These setups hit the same API. You need a key, then you upload a file and create a post.
Zapier
A Zap that uploads a file and posts it. Three webhook steps.
Open setup
Make
Three HTTP modules in a scenario. Same upload, PUT, and post calls.
Open setup
n8n
HTTP Request nodes on your own instance. Header Auth with your API key.
Open setup
Airtable
A script when a row is Ready. Writes the job id back onto the record.
Open setup
If you do not already run Zapier, Make, n8n, or Airtable, skip this page.
The same three calls
- Create a key and send it as Authorization: Bearer pk_live_…. API keys
- POST https://api.post-uno.com/v1/media/upload-url for an upload URL, then PUT the file bytes to uploadUrl. You get back s3Key.
- POST https://api.post-uno.com/v1/posts with that key. Poll GET https://api.post-uno.com/v1/posts/:jobId to see each platform.
Carousels use s3Keys. TikTok and YouTube take video only.
