- [Authentication and connections](/beam/api-guides/getting-started/authentication): prepare cloud or device access.
- [Your first API call](/beam/api-guides/getting-started/first-api-call): list registered devices with the Fleets API.
- [Connect to a Beam device](/beam/api-guides/how-to/channels/connect-to-a-device): prepare a device-local Channels API workflow.
