I have created my own GPT with custom data about my business, Now I want to use it as a chatbot in my personal website. How to do that? Which API i need to use exactly to get this connected?
ChatGPT can only be used through OpenAIs website. If you want something more advanced you have to request API access and do everything through that.
You should try GitHub - SamurAIGPT/Open-Custom-GPT: Create Custom GPT and add/embed on your site using Assistants api , an open-source project to allow creating and hosting GPTs on your site
