Move from Upload-Post to PostWire in an afternoon

Upload-Post — their docs' example

curl \
  -H 'Authorization: Apikey your-api-key-here' \
  -F 'video=@/path/to/your/video.mp4' \
  -F 'title="Your Video Title"' \
  -F 'user="test"' \
  -F 'platform[]=tiktok' \
  -X POST https://api.upload-post.com/api/upload

PostWire — REST (the converter's output)

curl -X POST https://postwire.io/api/post \
  -H "Authorization: Bearer $POSTWIRE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "platforms": [
    "tiktok"
  ],
  "text": "Your Video Title"
}'

your key from the pasted command is not carried over: the output uses $POSTWIRE_API_KEY video @/path/to/your/video.mp4 is a local file: upload it (POST /api/media/upload-url) and pass its URL as video_url user (an Upload-Post profile) → brand_id: create one PostWire brand per client (POST /api/brands) and send its id; with a single brand you can leave brand_id out
