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

Bearer TokenAuthorization

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.

Path Parameters

accountSlugstring Required

The Account's slug. An unknown one answers 404.

appSlugstring Required

The Application's slug within the Account.

envSlugstring Required

The Environment's slug within the Application.

Request body

Errors

When the request can't be completed, the response body includes a stable error code you can branch on, and a correlation_id (also sent as the X-Correlation-Id header). Quote the correlation id when you contact support: it identifies the exact request in Canopy's logs.

When it happens

The signed-in user's administrator roles do not grant the capability this endpoint requires.

Remediation

Ask an account administrator to grant a role carrying the capability named in the Authentication section, then retry.
