# Rest API
> Connect any system to Smart Send using our Rest API.
## Use the Smart Send API
You can use the Smart Send REST API to create shipping labels and manage shipments from any external system. All official Smart Send integrations use this same API, ensuring reliability and consistency across platforms.
The API is suitable for custom integrations, automation, or connecting third-party systems to Smart Send.
See our OpenAPI specification
## Authentication
All requests to the Smart Send API require authentication using an API token. The token must be included in the `Authorization` header as a Bearer token.
