It opens the doors to do a lot of different things.

Note: To create your own GTP, you need the ChatGPT Plus subscription which costs (today 10 December 2023) USD $20 with a limit of 40 messages/3 Hrs

The beauty of GPT Editor is you will see the “GPT Builder” which is the AI Assistant to build your GPT 😀

It means, You need to chat with the GPT Builder and tell how you want to build your GPT.

In this article, I want to explain how you can use WordPress APIs to connect your own WordPress website and create page, post, or whatever you want to do on your WordPress website.

#Step 5: GPT Basic Configuration Step 5: GPT Basic Configuration

In the basic configuration, you can enter the following:

• Name: It’ll be the name of your GPT name.
• Description: Your GPT description.
• Instructions: Enter the instruction that your GPT will perform.

I filled in the details below:

You can fill it in as per your requirements.

#Step 6: Add your WordPress APIs as GPT Action Step 6: Add your WordPress APIs as GPT Action

Now, In the GPT, You’ll see the Actions section with the Create new action button as below:

On click on it, You’ll see the add action screen something as below:

Here, You can add the API Authentication, API Schema, etc.

To connect to the WordPress website, we will use the Application Passwords.

You can read more about how to create, setup, and test Application Passwords.

Important: You can publish the GPT and share it with anyone. I STRONGLY recommend using a different Authentication method when you want to use it with the public. You can use oAuth as well.

#Convert the username:password with base64 Convert the username:password with base64

Now, You need to convert your <username:application-password> into the base64 format.

You can use the website https://www.base64encode.org/

E.g. Your username is maheshwaghmare and the application password is GsRGm cOdH homZ SeXsS Beal cwDi then you can enter the string as:

maheshwaghmare:GsRGm cOdH homZ SeXsS Beal cwDi

Now, You can use the encoded string bWFoZXNod2FnaG1hcmU6R3NSR20gY09kSCBob21aIFNlWHNTIEJlYWwgY3dEaQ== as your API Key in OpenAI GPT Editor.

#Set Authentication as API Key Set Authentication as API Key

After setting up the Application Password, Click on the settings icon from the Add action screen:

After click you’ll see the popup as:

Now,

• Select the API Key from Application Type
• Enter the above key as API Key
• Select the Basic as Auth Type
• And click on the Save button.

Great. Now you are ready to enter your WordPress API Schema.
