Publish and manage blog content on a WordPress site via the built-in WP REST API (/wp-json/wp/v2/...), authenticated with an Application Password — no OAuth app needed.

Draft-first rule

Every post is created with "status": "draft" first. Show the draft (title + body + any scheduled time) to the human and get explicit approval before flipping status to publish or future. Never create a post directly as publish.

Setup

1. In WordPress admin: Users → Profile (for the account you'll post as) → scroll to "Application Passwords" → enter a name (e.g. "MarketingClaw") → Add New Application Password.
2. Copy the generated password (shown once, spaces included).
3. Set environment variables:

   export WORDPRESS_URL="https://yourblog.example.com"
   export WORDPRESS_USER="your-wp-username"
   export WORDPRESS_APP_PASSWORD="xxxx xxxx xxxx xxxx xxxx xxxx"   # keep the spaces
   

4. Application Passwords require HTTPS on the site (or WP_ENVIRONMENT_TYPE=local for local dev).

All requests use HTTP Basic auth: curl -u "$WORDPRESS_USER:$WORDPRESS_APP_PASSWORD".

Create a draft post

curl -s -u "$WORDPRESS_USER:$WORDPRESS_APP_PASSWORD" \
  -X POST "${WORDPRESS_URL%/}/wp-json/wp/v2/posts" \
  -H "Content-Type: application/json" \
  -d '{
    "title": "5 Things We Learned Shipping v2",
    "content": "<p>Full post body as HTML...</p>",
    "status": "draft",
    "categories": [3],
    "tags": [12, 18]
  }' | jq '{id, link, status}'

Update a post / publish / schedule

# Publish now (only after approval)
curl -s -u "$WORDPRESS_USER:$WORDPRESS_APP_PASSWORD" \
  -X POST "${WORDPRESS_URL%/}/wp-json/wp/v2/posts/POST_ID" \
  -H "Content-Type: application/json" \
  -d '{"status": "publish"}' | jq '{id, link, status}'

# Schedule for later (only after approval) — status=future + a future "date" (site-local time)
curl -s -u "$WORDPRESS_USER:$WORDPRESS_APP_PASSWORD" \
  -X POST "${WORDPRESS_URL%/}/wp-json/wp/v2/posts/POST_ID" \
  -H "Content-Type: application/json" \
  -d '{"status": "future", "date": "2026-07-15T09:00:00"}' | jq '{id, link, status, date}'

date is site-local time without a timezone suffix; use date_gmt (with a Z suffix) instead if you want to specify UTC explicitly.

Media upload

curl -s -u "$WORDPRESS_USER:$WORDPRESS_APP_PASSWORD" \
  -X POST "${WORDPRESS_URL%/}/wp-json/wp/v2/media" \
  -H "Content-Disposition: attachment; filename=\"hero.jpg\"" \
  -H "Content-Type: image/jpeg" \
  --data-binary "@/path/to/hero.jpg" | jq '{id, source_url}'

# Set as the post's featured image
curl -s -u "$WORDPRESS_USER:$WORDPRESS_APP_PASSWORD" \
  -X POST "${WORDPRESS_URL%/}/wp-json/wp/v2/posts/POST_ID" \
  -H "Content-Type: application/json" \
  -d '{"featured_media": MEDIA_ID}' | jq '{id, featured_media}'

Categories and tags

# List / find
curl -s -u "$WORDPRESS_USER:$WORDPRESS_APP_PASSWORD" "${WORDPRESS_URL%/}/wp-json/wp/v2/categories?per_page=100" | jq '.[] | {id, name}'
curl -s -u "$WORDPRESS_USER:$WORDPRESS_APP_PASSWORD" "${WORDPRESS_URL%/}/wp-json/wp/v2/tags?per_page=100" | jq '.[] | {id, name}'

# Create
curl -s -u "$WORDPRESS_USER:$WORDPRESS_APP_PASSWORD" -X POST "${WORDPRESS_URL%/}/wp-json/wp/v2/categories" \
  -H "Content-Type: application/json" -d '{"name": "Product"}' | jq '{id, name}'
curl -s -u "$WORDPRESS_USER:$WORDPRESS_APP_PASSWORD" -X POST "${WORDPRESS_URL%/}/wp-json/wp/v2/tags" \
  -H "Content-Type: application/json" -d '{"name": "launch"}' | jq '{id, name}'

List / check posts

curl -s -u "$WORDPRESS_USER:$WORDPRESS_APP_PASSWORD" \
  "${WORDPRESS_URL%/}/wp-json/wp/v2/posts?status=draft,future,publish&per_page=20" | \
  jq '.[] | {id, title: .title.rendered, status, date, link}'

Note: filtering by non-publish statuses requires an authenticated request (Basic auth above) — anonymous requests only ever see published posts.

Notes

• content accepts raw HTML (Gutenberg block markup or plain HTML both render fine); avoid hand-writing block comments unless you need specific block behavior.
• Rate limits are host-dependent (WordPress core has none by default; managed hosts like WordPress.com or WP Engine may throttle) — back off on 429s.
• Application Passwords can be revoked per-app from the same Profile screen without touching the user's main login password.
• Never print $WORDPRESS_APP_PASSWORD in logs or chat.
