Destination Reference

Destination definitions declare an analytics provider configuration — the credentials, batching settings, and other parameters for a specific backend.

File location

destinations/<destination_name>.yaml

Fields

Field	Type	Required	Description
name	string	Yes	Machine-readable destination name. Referenced in source destinations lists.
type	string	Yes	Provider type: amplitude | noop | (future providers)
config	object	No	Provider-specific configuration. Keys depend on type.

Amplitude config

destinations/amplitude.yaml

name: amplitude
type: amplitude
config:
  api_key: "${AMPLITUDE_API_KEY}"
  batch_size: 100
  flush_interval: "5s"
  max_queue_size: 10000
  proxy_url: "https://analytics.yourcompany.com/amp"

Config key	Type	Description
api_key	string	Amplitude API key or ${ENV_VAR} reference
batch_size	integer	Max events per batch HTTP request
flush_interval	duration	How often to flush the event queue
max_queue_size	integer	Max buffered events before overflow policy kicks in
proxy_url	string	Optional reverse proxy URL

Environment variable expansion

Any config value of the form ${VAR_NAME} is expanded from the environment at runtime. Never store raw API keys in destination YAML files.
