How to post your Etsy product videos to TikTok from ChatGPT or Claude

Set it up and post, step by step

Prompt to copy once TikTok is connected: I sell handmade birthday cards on Etsy. Write a TikTok caption for this video of the new pressed-flower card, mention my shop name "Paper Meadow", show it to me, and post it public tonight at 7pm my time.

1. Add PostWire to ChatGPT or Claude

   In ChatGPT, open PostWire in the app directory (or search for PostWire in ChatGPT's apps) and add it. In Claude, open PostWire in the connector directory and press Connect; it works on the web, the desktop app and the phone. A sign-in window asks for your email and a 6-digit code, which also creates a free PostWire account if you have none: no password and no card.

2. Connect your TikTok account

   Ask "connect my TikTok". The assistant calls create_connect_link and gives you a one-hour link; open it, sign in on TikTok's own page and allow PostWire to post. You do it once, and the assistant never sees your TikTok password.

3. Send the product video from your phone

   Say "I want to post a video". A file attached to the chat does not reach a connector, so the assistant gives you an upload page (create_upload_link): open it on the phone or laptop that has the clip and pick the file, up to 100 MB on the free plan and 1 GB on paid plans. Then say "uploaded" and it reads the file with get_uploaded_file. MP4 and MOV both work.

4. Or use your listing photos

   No video for this product? Give the assistant the photos (through the same upload page, or the public https links of the images) and it makes a TikTok photo post of 1 to 35 images; PNG files are turned into JPEG for you.

5. Tell it about the product and approve the caption

   Say what it is, who it is for and the shop's name. generate_posts returns a draft and publishes nothing: a first line that stops the scroll and a few specific hashtags, within TikTok's 2,200 characters. Ask for changes in plain words. Then say who can see it: public, friends or private. TikTok asks the account owner to choose for every post; if nobody chooses, PostWire posts it private and says so.

6. Post now, or schedule the week

   Say "post it" and the assistant calls post_to_social. Say "schedule it for Friday at 7pm" and it calls schedule_post, up to 365 days ahead. This is the call it makes:

   {
     "name": "schedule_post",
     "arguments": {
       "platforms": ["tiktok"],
       "per_platform": { "tiktok": {
         "text": "Pressed flowers, one at a time 🌼 New birthday card in the Paper Meadow shop on Etsy. #handmadecards #etsyseller #pressedflowers"
       } },
       "video_url": "https://postwire.io/m/…/pressed-flower-card.mp4",
       "privacy": "public",
       "run_at": "2026-11-13T19:00:00-05:00"
     }
   }

7. Get the TikTok link

   TikTok processes the video after the call returns. The assistant checks with get_post_status until it has the TikTok link, usually within a minute or two. If TikTok refuses the video, the answer says what happened and what to change.

"What's scheduled on TikTok?" calls list_scheduled_posts and "cancel Friday's video" calls cancel_scheduled_post; the same queue is on the dashboard's Queue page. Prefer to try it by hand first? Open the dashboard, connect TikTok under Accounts and post the same video from the composer.
