# Environments and API Key Types
UserFlux provides two distinct environments to ensure you can develop and test safely without affecting your live user data.
* **Production:** Your live environment where real user data is processed.
* **Test:** A sandbox environment for development, testing, and staging. Use this to try new things before publishing to production.
You can switch between these environments using the dropdown menu in the bottom-left corner of your dashboard.
#### API Key Categories
UserFlux provides three categories of APIs, each with its own set of keys for both the Test and Production environments.
* **Integration API:** The primary API used for most integrations. It allows you to update user properties and create new events. Use these API keys when integrating with the SDK and collecting data.
* **Data API:** Used for querying your data warehouse to read metrics or embed analytics into your own applications.
* **Product API:** Used specifically for synchronising your product catalogue and schemas with UserFlux.
> Each API key has specific permissions (e.g., Read-Only, Write-Only, Read and Write) to ensure secure and controlled access.
