--- title: "Quick start" --- ## Get your API keys Your API requests are authenticated using API keys. Any request that doesn't include an API key will return an error. You can generate an API key from **Settings >** [**Security**](https://app.cal.com/settings/security) within the application. There you will find the API keys section which allows you to generate a key for use. More information on this can be found in the [Authentication](authentication) page. ## Install the library The best way to interact with our API is using a good HTTP client like **axios**: ``` # Install via NPM npm install --save axios # Install via Yarn yarn add axios ``` ``` # Install via pip pip install --upgrade requests ``` ## Make your first request To make your first request, send an authenticated request to the event-types endpoint. This will list all of your event types. Example using `curl`: ``` curl https://api.cal.com/v1/event-types?apiKey=cal_test_xxxxxx ``` ## Try our Postman Collection We've created a small collection of frequently made API calls that you can try in our [Postman Collection](https://www.postman.com/calcom/workspace/cd670dd8-b36d-4aee-8ab2-9044122e30d1/collection/20666831-b92a1d73-bfcc-4a5f-9ef5-cb117d49c904)
