# API Keys

## Three kinds of API Keys

API keys are an integral part of calling rules.

To use [Rule Solver](https://docs.decisionrules.io/doc/api/rule-solver-api) in your application, you need to have a solver API key.

To manage rules through our API in your application, you need to have a Management API key.

To get data about the rule solver activity for business intelligence, you need to have a BI API Key.
