How to post a video to TikTok from Make.com

Step by step

1. Create a free PostWire account

   Open postwire.io/dashboard.html, type your email and press Create my free account. PostWire emails you a link to confirm the address; connecting accounts and publishing unlock once it is confirmed. No password and no card (free plan: 1 business, 30 posts a month, 15 AI drafts a day, every live network, no card).

2. Connect TikTok (and Instagram, YouTube if you want them)

   Accounts → Connect → Continue to TikTok. You sign in on TikTok; PostWire's Direct Post approval (audited July 7, 2026) means posts can be public.

3. Copy your API key

   In the dashboard, open API & MCP and press Copy key on the API key card. It is sent as Authorization: Bearer pw_live_… (the X-API-Key header also works). Keep it server-side.

4. Add Make's HTTP module

   In your scenario, after the step that produces the video (Google Drive, Dropbox, an AI video tool), add HTTP → Make a request. URL https://postwire.io/api/post, Method POST, header Authorization = Bearer pw_live_…, Body type Raw, Content type JSON (application/json).

5. Put the video URL and caption in the body

   The video URL must be public and point at the file (up to 1 GB). Map the fields from earlier modules:

   {
     "platforms": ["tiktok", "instagram", "youtube"],
     "video_url": "{{1.video_url}}",
     "text": "{{1.caption}}",
     "title": "{{1.title}}",
     "privacy": "public",
     "idempotency_key": "{{1.id}}"
   }

6. Want a caption written per network?

   Add one more HTTP module before it: POST https://postwire.io/api/generate with {"prompt":"{{1.description}}","platforms":["tiktok","instagram","youtube"],"media_url":"{{1.video_url}}"}, then send its drafts as per_platform instead of text.

7. Run it once and check

   The response lists each network's result and link. TikTok and YouTube keep processing for a moment; GET https://postwire.io/api/post/status reports when the post is live. To publish later, POST to /api/schedule with a run_at (ISO 8601 with offset).

Without "privacy": "public" the TikTok post is private (only you can see it) — that is TikTok's rule for API posts without an explicit choice. Sending the same payload twice within 2 minutes is refused, and with an idempotency_key for 24 hours, so a re-run never double-posts.
