# Authorization

The intratool API routes are protected by the OAuth2 protocol. To get access to API data, users need to authorize with an [Authorization Token](/introduction/authorization/get-token.md) which is granted by the customer's system.

Each user on intratool can have multiple clients and tokens associated. **Authorization tokens** will only grant access to the components and data the granting user is permitted to use.
