Innovations Unleashed: 10 Step-By Step Guide on Creating ChatgGPT API Plug In

There are three main ingredients to a ChatGPT plugin: the app

file (main.py), the plugin manifest file (ai-plugin.json) and

OpenAPI definition (openapi.yaml).

Step 1: Finding an API key

In order to create a ChatGPT, you need to first connect an API

key from an alternative platform.

Think of this more as the data set that you are pulling

information from - the same info that will be output to the

user.

You can see how the process works via the photo above.

Human Input -> ChatGPT -> API Key -> Info -> ChatGPT Output

So, find your API key!

In this picture below example, I use the NewsAPI, as I want my plugin to be a source that users can instantly get the newest news

Step 2: Fill Out the Plugin Template

Essentially, these are the assets that ChatGPT will need in

order to create the plugin:

$GENERAL_PROMPT_SCOPE

This will be the overall solution that your plugin will be used for. Think

of the problem that you want to solve, and work your way backwards.

$EXAMPLE_PROMPTS

These are the inputs that the user of your plugin would be expected

to say!

If your plugin was a weather predictor app, this would be something

like "Hey $Plugin_Name, what will the weather look like next week?"

$INFO_NEEDED_FOR_FUNCTIONALITY

All the info needed for your plugin to work!

In the weather example, this would be info such as: Dates, Times,

Location, etc.

***Find the plugin template in the Suffix***

$FUNCTIONALITY_LIMIT

Things that you don't want your users to be able to

search/input information into.

In the weather plugin example, this would be something like:

"Hey $Plugin_Name, what are your sources for this info?"

Once you've entered all the relevant info for your plugin, we can move to next step.

Step 3: Create a Replit Account

To free create code that works for API plugins, you'll need to

first create a Replit account.

As soon as you've done this, let's enter it back into the

template:

Step 4: Create the main.py code

From here, you will COPY THE WHOLE section from XXXX

Paste this into ChatGPT, and receive your first set of code.

Great, now let's put this back into Replit:

Step 5: Create the manifest file

These have been included in the prompt template for you

already.

Simply copy and paste these from Notion into your Replit.

Step 6: Enter the OpenAI API Key Info

For this, you'll need to get your own API key.

Search up "OpenAI API Key" on your search browser, and

find the information below:

Enter your info into the template, and then step 7.

Step 7: Create your OpenAPI definition

Copying the highlighted section of the Notion template,

paste this into ChatGPT to create your OpenAPI definition.

Step 8: Paste OpenAPI definition into Replit

After you've created the main.py, the manifest file, and the

OpenAPI definition, you are ready to upload.

Step 9: Upload your new plugin.

To upload your new plugin, click "New Chat" while on

ChatGPT.

Go to the right hand side, and click "Plugins."

***If you don't have access to ChatGPT's plugins yet, this

won't be visible from your side***

From "Plugins" , go to "Plugin Store".

Click "Create New"!

Enter the url from your Replit code:

and upload your files

Step 10: Enjoy your plugin!

After you've done the previous steps, play with your plugin!

You created this piece of art - now put it to the test!
