Schedule TikTok carousels and photo posts that publish themselves

Schedule a TikTok carousel, 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, 10 posts a month, 5 AI drafts a day (about 20 a month), 2 networks per post, 3 scheduled posts at a time — every network connects free, no card).

2. Connect TikTok

   Open Accounts, press Connect on TikTok and then Continue to TikTok. You sign in on TikTok itself; PostWire never sees your password and you do not need your own developer app.

3. Add the photos in order

   In Compose, write in Your idea, tick TikTok under Post to and add up to 35 images on Add photos or a video. The first one is the cover by default. PNG files are converted to JPEG for you.

4. Choose who can view it

   Under Who can view this video, pick the audience. TikTok asks the account owner to choose this for each post, and a post with no choice goes out private.

5. Pick the time and queue it

   Press Schedule, set the day and time, then Add to queue. That is the last thing you do: at that time PostWire publishes through TikTok's API, and the post appears under Queue until it runs.

6. Or schedule it from code: 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. Then send the photos to POST /api/schedule. media keeps your order, privacy sets the audience and run_at takes an ISO 8601 time or "next_slot" for your next free queue slot.

   curl -X POST "https://postwire.io/api/schedule" \
     -H "Authorization: Bearer $POSTWIRE_API_KEY" \
     -H "Content-Type: application/json" \
     -d '{

In Claude or another MCP client, connect https://postwire.io/api/mcp and the schedule_post tool takes the same media, privacy and run_at; create_upload_link gets photos from your phone. See TikTok over MCP. For a weekly set, PostWire's n8n node can send the same request, or start in the dashboard.
