We’ve added two new mutations to manage the targets of your webhook subscriptions:
addWebhookSubscriptionTarget— add a new organization/office target to an existing webhook subscription.removeWebhookSubscriptionTarget— remove an existing target from a webhook subscription.
Both mutations accept a webhookSubscriptionId and a target consisting of an organizationKey and optional officeKeys. Like the existing webhook mutations, these require the api-management scope to be granted to your API client.
See the Webhooks documentation for more details.
