GPT-Commerce allows you to create GPTs in OpenAI that turns your GPT into an "AI-based E-Commerce system", allowing users to purchase products by writing things such as:
- "What products do you have?"
- "How much is your 'xyz' product?"
- "I want to buy 'xyz'"
- Etc ...
You can use Manage/Endpoints and filter on "openapi" for the to invoke it with a filter of "gpt-commerce/public". Then copy the OpenAPI specification link, and paste into a custom GPT as an "action".
In order to make your GPT perform correctly you'll have to add an instruction to it resembling the following:
If I tell you I want to purchase something, then unless you know the product I want, list all products using the products action, ask me what product I want, for then to pass in the price_reference into the purchase action and display the returned payment link as a Markdown hyperlink.
If you wish you can create another GPT that is private only for you, where you repeat the process from above except
you should use "gpt-commerce" as your invocation filter to the openapi endpoint. This allows you to create another
GPT that only you can access allowing you to administrate your products using phrases such as:
- "Change the price of product 'xyz' to 67.50"
- "Create a new product named 'qwerty' with a price of 99 and a price reference of 'price_xyz'"
- "Delete the product named 'xyz'"
- Etc ...
To administrate your products in your private GPT you would probably want it to have a system message resembling the following:
If I tell you to do CRUD operations towards my products, assume I want to use the products action. If I provide you with incomplete information, ask me questions until you've got everything you need. If my endpoint doesn't return anything, then inform me that nothing was returned.
