CLI Authentication - FirstSales Developer

Use environment variables for agents and CI:

export FIRSTSALES_API_KEY="fs_..."
export FIRSTSALES_BASE_URL="https://api.app.firstsales.io"

Or pass flags:

firstsales whoami --api-key "$FIRSTSALES_API_KEY" --base-url https://api.app.firstsales.io

The CLI supports local profiles for developer machines. Environment variables are preferred for automation because they are explicit and easier to rotate. firstsales auth login saves a Developer API-key profile. For automation, prefer the existing environment variable. Sender Connector tokens are separate from account credentials.

firstsales auth login --api-key "$FIRSTSALES_API_KEY" --profile production
firstsales auth status --profile production --json

Confirm supported flags with firstsales auth login --help. GitHub, Google and email account signup/login inside the CLI are pending. App account sign-in and Product MCP OAuth consent do not automatically create a CLI API-key profile. See API authentication and Product MCP authentication.
