Schema change notifications

You can configure GraphOS to notify your team whenever any changes (additions, deprecations, removals, etc.) are made to your graph's registered schema:

You can configure separate change notifications for each variant of your graph.

Setup

See Setting up GraphOS Notifications.

Webhook format

If you receive schema change notifications via a custom webhook, notification details are provided as a JSON object in the request body.

The JSON object conforms to the structure of the ResponseShape interface:

1
interface Change {
2
  description: string;
3
}
4

5
interface ResponseShape {
6
  eventType: "SCHEMA_PUBLISH"; // Currently, only SCHEMA_PUBLISH webhooks are supported
7
  eventID: string;
8
  changes: Change[]; // Set of schema changes that occurred
9
  schemaURL: string; // See description below
10
  schemaURLExpiresAt: string; // ISO 8601 Date string
11
  graphID: string;
12
  variantID: string; // See description below
13
  timestamp: string; // ISO 8601 Date string
14
}

• The value of schemaURL is a short-lived (24-hour) URL that enables you to fetch the published schema without authenticating (such as with an API key). The URL expires at the time indicated by schemaURLExpiresAt.

• The value of variantID is in the format graphID@variantName (for example, mygraph@staging).
