Create a webhook subscription

POST/portal/v1/accounts/{accountSlug}/applications/{appSlug}/environments/{envSlug}/webhooks

Creates a webhook subscription for the active Application's current Environment from a url, an event_types array, and an optional description. Use ["*"] to subscribe to all events (current and future); the wildcard cannot be mixed with concrete types, and any unsupported event type returns 400. The response includes a freshly minted HMAC signing secret that is shown only once at creation — store it to verify delivery signatures. Requires the webhook.manage permission.

Authentication

JWT access token. Never send alongside X-API-Key: a request carrying both is refused.

Requires capability env_webhooks.manageDeveloper Console

Create, edit, rotate, and delete Environment webhook subscriptions. Granted through an administrator role in the Admin Workspace; a valid token without it is refused with 403.
