Event Webhook

Incoming

The Statsig Event Webhook allows you to log event data to Statsig from third party apps or other external sources to provide additional insights to your Statsig experiments and metrics.

Before using the Webhook, you will need to obtain your Projects' server secret key. An example call to the Statsig Event Webhook should look like the following:

HTTP
POST https://api.statsig.com/v1/webhooks/event_webhook
Headers
Content-Type: application/json
Accept: */*
STATSIG-API-KEY: {STATSIG_SERVER_SECRET}
JSON Body
{
"user": {
"userID": {USER_ID},
...
},
"event": {EVENT_NAME},
"value": {VALUE},
"metadata": {
"example_field_1": {EXAMPLE_VALUE_1},
"example_field_2": {EXAMPLE_VALUE_2},
...
},
timestamp: {TIMESTAMP}
}

Outgoing

If you are using a service that we don't have an official integration for, you can always use our Generic Webhook integration.

This integration just sends raw events to the provided webhook url.

Setup

In your Project Settings, under the Integrations tab. Enable the Generic Webhook integration.

In the dialog that appears, enter the url of you destination webhook and then hit Enable to save the url and enable this integration.

integration-dialog

You can then set which events you want forwarded to your webhook using the Event Filtering dialog.

Event Format

Events will be sent in batches in a JSON format. The structure of a Statsig Event sent will look like the following:

userIDStringUser ID provided
timestampNumberTimestamp in MS of the event
valueStringValue of the event provided
metadataJSONCustom Metadata provided
statsigMetadataJSONMetadata related to the logging of this event added by Statsig
