I know that you all know that this is possible, especially with the addition of ChatGPT’s agent function. This is how Annie o3 describes what I should do for “Happy Publishing.”

Below is a practical, end‑to‑end blueprint for turning ChatGPT’s new agent feature into a “one‑click” WordPress blogger—covering both a direct REST‑API path and a no‑code plugin path.

1. Gather the prerequisites

2. Decide which integration route fits you

The two methods can happily coexist—use the plugin for day‑to‑day chat widgets and the REST path for fully‑automated publishing.

3. If you choose the REST‑API path

3‑A  Create a function schema for the agent

{
  "name": "create_wordpress_post",
  "description": "Publish or schedule a blog post to WordPress via REST API",
  "parameters": {
    "type": "object",
    "properties": {
      "title":  { "type": "string" },
      "content":{ "type": "string" },
      "status": { "type": "string", "enum":["draft","publish","future"], "default":"draft" },
      "categories": { "type":"array","items":{"type":"integer"} },
      "tags":       { "type":"array","items":{"type":"integer"} }
    },
    "required": ["title","content"]
  }
}

3‑B  Give the agent the “action wrapper” (example in Python)

import os, requests, base64, json, datetime as dt, openai, tiktoken  # etc.

WP_USER      = os.getenv("WP_USER")
WP_APP_PASS  = os.getenv("WP_APP_PASS")           # application‑password
WP_SITE      = "https://example.com"
AUTH_HEADER  = {"Authorization": "Basic " + base64.b64encode(f"{WP_USER}:{WP_APP_PASS}".encode()).decode()}

def create_wordpress_post(title, content, status="draft", categories=None, tags=None):
    payload = {
        "title": title,
        "content": content,
        "status": status,
        "categories": categories or [],
        "tags": tags or []
    }
    r = requests.post(f"{WP_SITE}/wp-json/wp/v2/posts", headers=AUTH_HEADER, json=payload, timeout=30)
    r.raise_for_status()
    return r.json()["link"]

Expose that function as a tool in the Assistants/Agents API (or let the Mac app auto‑scan your script directory).

3‑C  Prompt workflow (what you type to ChatGPT)

1. “Draft a 1 500‑word post on ‘Zero‑shot prompting for marketers’, friendly tone, include 3 bullet take‑aways.”
2. “Looks good—now call create_wordpress_post with status=draft and category=203.”
3. ChatGPT agent runs, hits your function, and returns the preview URL.

3‑D  Review & publish

Open the returned draft URL, tweak formatting, set a featured image, then click Publish (or have the agent update the post via PATCH /posts/{id} if you expose a second function).

4. If you prefer the plugin path (BuddyBot)

1. Install & activate “BuddyBot – OpenAI Assistants” from Plugins ▸ Add New.
2. Paste your OpenAI API key in Settings ▸ BuddyBot.
3. (Optional) Let the plugin index your existing posts for richer context.
4. Create a new Assistant inside BuddyBot or import your existing GPT‑based agent.
5. In its toolbox, enable “Create Post” & “Update Post” actions.
6. Drop [buddybot] shortcode into any admin screen or post editor.
7. Now chat: “Write & publish a 700‑word summary of today’s earnings call, include the embedded transcript link, tag ‘Earnings’.”

5. Tips for better results

• Stage first, publish second. Default the status to “draft” until you trust the flow.
• Pass SEO context. Give the agent your target keyword, meta‑description length, and slug style.
• Limit credentials. Application Passwords let you revoke one agent without locking your entire login.
• Validate output. For legal/brand compliance, add a manual “Hold for review” step or an approval function.
• Schedule like a pro. Set status:"future" and a date string (ISO 8601) to queue posts. (WordPress Developer Resources)

6. What Agent mode actually does under the hood

ChatGPT Agent “thinks and acts,” deciding whether to reason internally or invoke a registered tool; it can chain browsing, file reads, and your WordPress function to complete the whole workflow in one go. (OpenAI Help Center)

That’s it! With a small function wrapper—or an install‑and‑go plugin—you can let ChatGPT Agent brainstorm, draft, and push WordPress posts while you focus on strategy. Happy publishing!
