About this video

Most people think you need a separate tool like N8N or Zapier to connect APIs. You don’t.

With Custom GPTs inside ChatGPT, you can add APIs directly. No extra platforms. No complicated setup.

Here’s how it works.
When you create a Custom GPT, there’s an “Actions” section. That’s where you can paste an OpenAI schema. This schema is just a structured format that tells ChatGPT how to talk to an API.

If you already have API code, you can simply ask ChatGPT itself to convert it into the OpenAI schema format. Then you paste it in, set your API key, and you’re done.

The best part? You can chain multiple APIs together. That means you can make ChatGPT pull data from one source, process it, and send it to another all in one conversation.

It’s like having your own mini automation system inside ChatGPT, without relying on third-party automation tools.

Once you understand the schema format, the possibilities are endless. From fetching live data to triggering actions in external apps, you can build your own agent without touching anything outside ChatGPT.
