How to Set Up a Custom ChatGPT Action for Your WordPress Blog

Integrating ChatGPT with your WordPress blog just got easier. With the power of the WordPress REST API and ChatGPT’s custom action capabilities, you can now create a seamless workflow for fetching, summarizing, and interacting with your blog posts. In this guide, we’ll walk you through the process step-by-step, using an example API schema to set up a custom ChatGPT action.

Why Connect ChatGPT with WordPress?

Connecting ChatGPT with your WordPress blog unlocks a world of possibilities:

• Content Summaries: Generate concise summaries of your latest posts.
• Efficient Retrieval: Fetch posts by keyword or category instantly.
• Automated Assistance: Provide ChatGPT users with accurate blog content in real-time.
• Draft Posts: Draft WordPress posts based on ChatGPT conversations.

Setting Up the Custom Action

Step 1: Define Your API Schema

To make this integration possible, you’ll need an OpenAPI schema. This schema tells ChatGPT how to interact with your WordPress blog. Here’s an example schema configured for the WordPress REST API:

{
  "openapi": "3.1.0",
  "info": {
    "title": "WordPress Blog Content API",
    "description": "API specification for retrieving blog posts to be used for ChatGPT content learning.",
    "version": "v1.0.0"
  },
  "servers": [
    {
      "url": "https://example.com/wp-json/wp/v2",
      "description": "Base URL for the WordPress REST API"
    }
  ],
  "paths": {
    "/search": {
      "get": {
        "summary": "Search blog posts",
        "parameters": [
          {
            "name": "search",
            "in": "query",
            "required": true,
            "schema": {
              "type": "string"
            }
          }
        ],
        "responses": {
          "200": {
            "description": "Search results."
          }
        }
      }
    }
  }
}

This schema defines endpoints like /search for searching blog posts.

Step 2: Upload the Schema in ChatGPT

1. Ensure you have a version of ChatGPT that supports Custom GPTs and API Actions (e.g., OpenAI Pro)
2. Open the ChatGPT Customization UI.
3. Create a new GPT and upload the OpenAPI schema.
4. Configure the actions, ensuring the Authorization header includes your Base64-encoded credentials. For example:

Authorization: Basic your_base64_encoded_credentials

Step 3: Configure the Actions

Define the endpoints:

• Draft Posts: Add a draft post from the ChatGPT prompt to your blog.
• Search Posts: Retrieve posts by keyword.
• Fetch Recent Posts: Get the latest blog posts.
• Get Post by ID: Retrieve the full content of a specific post.

If you need help, here is my ChatGPT scheme file for all these actions. View the raw version for the gist and “Import from URL” it into ChatGPT. Replace “example.com” with your blog’s URL.

Step 4: Test Your Setup

Ask ChatGPT to interact with your blog:

• “Fetch the latest 5 posts.”
• “Search for posts about WordPress plugins.”

Conclusion

Integrating ChatGPT with WordPress doesn’t have to be complicated. By defining a clear API schema and configuring custom actions, you can unlock powerful automation and interaction for your blog. Start connecting your content today and watch as your blog becomes a dynamic, user-friendly hub for your audience.
