Destinations

Destinations are the endpoints where walkerOS sends your processed events. They transform standardized walkerOS events into the specific formats required by analytics platforms, marketing tools, data warehouses, and custom APIs.

Each destination operates independently, so one failed destination won't affect others.

Configuration

These fields are available on every destination, regardless of package. They wrap the package-specific settings field, which is documented on each destination's page.

Property	Type	Description	More
consent	WalkerOS.Consent	Required consent states to send events to this destination
settings	Destination.Settings	Implementation-specific configuration
data	any | any	Global data transformation applied to all events for this destination
include	Array<string>	Event sections to flatten into context.data
env	Destination.Env	Environment dependencies (platform-specific)
id	string	Destination instance identifier (defaults to destination key)
init	boolean	Whether to initialize immediately
loadScript	boolean	Whether to load external script (for web destinations)
mapping	Mapping.Rules	Entity-action specific mapping rules for this destination
policy	Mapping.Policy	Pre-processing policy rules applied before event mapping
queue	boolean	Whether to queue events when consent is not granted
require	Array<string>	Defer destination initialization until these collector events fire (e.g., ["consent"])
logger	Logger.Config
setup	boolean | object	One-time setup options applied during destination registration (boolean enables defaults, object configures specifics)
before	RouteWithoutMany	Post-collector transformer chain applied before this destination receives the event. `many` is not valid here — use multiple destinations for post-collector fan-out.
next	RouteWithoutMany	Post-push transformer chain. Runs after destination push completes; push response is available at ingest._response. `many` is not valid here — use multiple destinations for post-collector fan-out.
cache	EventCache.Config	Cache configuration for deduplication; skip push on cache HIT
state	State.Config | State.Config[]	Declarative store get/set operations applied around this destination
disabled	boolean	Completely skip this destination (no init, no push, no queue)
mock	Destination.Mock
queueMax	number	Maximum consent-denied events retained in queuePush for this destination. FIFO drop on overflow. Default 1000.
dlqMax	number	Maximum failed-push entries retained in dlq for this destination. FIFO drop on overflow. Default 100.
batch	number | object	Batch scheduling: bare number is the debounce wait window (legacy); object form supports wait (debounce ms), size (count cap, default 1000), age (max ms since first entry, default 30000).
