Resumable upload
We init the session and stream the bytes — the correct, reliable path.

The YouTube API, resumable upload, one call
Upload videos and Shorts to YouTube. We open a resumable session, stream your file, and set the metadata — you send a title, description, and a link to the file.

Why not raw?
YouTube Data API v3 is powerful — and painful
The official API can do this. It just makes you do a lot first. Here's what raw YouTube publishing costs you, and what PostMyIsh absorbs.
Raw YouTube API
With PostMyIsh
Upload
videos.insert as a resumable, multi-step byte upload
One POST /v1/posts; we run the resumable session
Auth
OAuth youtube.upload behind Google's security review
One OAuth screen, one encrypted token
Quota
An upload costs ~1,600 of the default 10k units/day
We track quota and surface it before you hit the wall
Verification
More than ~100 users needs Google OAuth app verification
One verification covers everyone you publish for
Capabilities
Everything YouTube supports, one endpoint
Post types, limits, and scheduling — all through the same POST /v1/posts call, formatted the way YouTube expects.
Shorts or long-form
A vertical clip lands as a Short; anything else as a standard video.
Metadata
First line becomes the title; the rest is the description.
Fan-out
Cross-post the same launch to TikTok and X in the same call.
Copy, paste, ship
Real calls, not pseudocode
Every snippet hits the live API — same base URL, Bearer auth, plain JSON. Add your key and it runs.
Publish to YouTube now
One POST fans out to YouTube. The response carries the id and status the moment it ships.

Live in three steps, not three weeks
Connect YouTube, call one endpoint, and we run the YouTube Data API v3 plumbing behind it.
Step 01
Connect the account
Link it once from the Accounts page through its official login. The credential is stored encrypted.
Step 02
POST /v1/posts
Send one caption and the platform id. Add schedule_at to queue it, or media for a URL.
Step 03
We handle the rest
Container flows, token refresh, rate limits, and the real post id — all on our side.
Straight talk: The upload scope needs Google's OAuth verification before ~100+ users can connect, and uploads draw on a daily quota. The resumable-upload code is complete — verification and quota are Google's gates.
YouTube API FAQ
The honest answers
What's real, what needs review, and what YouTube itself requires — no hand-waving.
Is this the official YouTube API?
Yes — the YouTube Data API v3 videos.insert endpoint with a resumable upload.
Can I upload Shorts?
Yes. YouTube classifies a vertical, short video as a Short automatically — upload it the same way.
What are the limits?
A video upload costs ~1,600 quota units against a default 10,000/day. Request more from Google for volume; we surface your usage.
Does it need review?
Google verifies apps that use the upload scope before more than ~100 users can connect. The code works today for test users; verification widens access.
