Post to YouTube from Make

Wire Make to one endpoint, then publish or schedule YouTube Shorts and long-form uploads from any trigger you already run — with a signed webhook for every delivery.

How it connects

An HTTP module pointed at one endpoint, with delivery receipts coming back as webhooks. There is nothing to install on the Make side and no per-network module to configure — YouTube is a channel id in the request body.

POST https://api.postwharf.com/v1/posts
Authorization: Bearer YOUR_WORKSPACE_KEY
Content-Type: application/json

{
  "text": "Shipping today.",
  "channels": ["ch_your_youtube_channel"]
}

A typical YouTube automation

The whole integration is a single HTTP module on the scenario canvas, usually right after the render finishes. Trigger on a finished render, then queue the post rather than publishing it straight away:

{
  "text": "New this week",
  "channels": ["ch_your_youtube_channel"],
  "publish_at": "2026-09-01T09:00:00Z"
}

Find the channel id once from GET /v1/channels — the one you want carries "platform": "youtube". Text longer than 5,000 characters is refused with a 422 in your hand, rather than accepted and rejected by YouTube minutes later.

A daily upload quota applies; the queue paces around it rather than failing the post.

Getting the result back

Register a webhook and every delivery outcome is posted to you — published, retrying, failed, or removed after publishing. Each is signed with HMAC-SHA256, so Make can verify it came from us before acting on it. That is the difference between a run that succeeded and a post that landed, and only the second one is worth a notification.

One thing worth setting up correctly

The canvas invites a router with a module per network. One call with every channel id costs fewer operations and leaves you one post to check instead of five scattered across the run history.

Questions

Can Make post to YouTube automatically?

Yes. Make calls one REST endpoint with a workspace key, so any trigger you already have can publish or schedule to a connected YouTube channel without a YouTube-specific module.

What do I need before YouTube will work?

A daily upload quota applies; the queue paces around it rather than failing the post. Once the channel is connected in PostWharf, Make reaches it the same way it reaches every other network.

How long can a YouTube post be?

5,000 characters, counted on the description. PostWharf checks that before the post is queued, so an over-length post is refused immediately rather than failing at YouTube after everything else in the same batch has already published.
