# Build a Custom Connector with AI

In [this previous session](https://prismatic.io/docs/get-started/build-integrations/custom-connector-basics.md) we introduced the concept of a custom connector, and walked through the steps to build a basic one. In this session, we'll build a fully functional custom connector that wraps a real API, includes data sources and actions, and connects to a third-party service with OAuth 2.0.

For this example, we'll wrap [todoist](https://www.todoist.com/) - a popular task management app that has a well-documented REST API and supports OAuth 2.0 authentication.

## Use Prismatic Claude skills to help build your connector[​](#use-prismatic-claude-skills-to-help-build-your-connector "Direct link to Use Prismatic Claude skills to help build your connector")

If you use an AI coding assistant like Claude Code you can leverage [Prismatic's AI skills](https://github.com/prismatic-io/prismatic-skills) to build your connector faster. These skills provide your AI agent with example code snippets, efficient documentation lookup, and best practice guidance.

Install Prismatic's AI skills in your coding assistant

Open `claude` and run the following commands to install Prismatic's marketplace and skills

Install Prismatic's AI marketplace and skills

```text
/plugin marketplace add prismatic-io/prismatic-skills
/plugin install prismatic-skills@prismatic-skills
/reload-plugins

```

Invoke the build-component skill with a prompt describing your connector

Then, invoke your newly-installed `build-component` command and skill with a prompt describing the connector you want to build

Prompt Claude to build your connector

```text
/prismatic-skills:build-component My customers use Todoist, and I would like
to interact with Todoist in a low-code integration.

Build a custom component for Todoist. API documentation is available at
https://developer.todoist.com/api/v1/

The component should include:

- OAuth 2.0 for authentication
- A data source where users can select a workspace from a dropdown menu
- A data source where users can select a project from a dropdown menu
- Actions for listing, creating, updating, closing and deleting tasks
- Actions for listing projects and workspaces

Remember to fetch a square PNG icon for the Todoist component and save it to assets/icon.png.

```

Your AI assistant will scaffold a custom connector project, install dependencies, write the data sources and actions and OAuth-based connection and import the connector into your Prismatic tenant for testing.
