## API Authentication Guide

Central Dispatch APIs provides two authorization flows to secure your API requests:

## Authorization Code Flow

Choose this flow when:

-   Your application needs to access API resources on behalf of a Central Dispatch customer.
-   You need customer-specific permissions and access.
-   For Software Providers/3rd party clients with CRM systems.

## Client Credentials Flow

Choose this flow when:

-   Making server-to-server API calls.
-   Your application needs to access API resources directly.
