# Read a webhook

`GET /webhooks/{id}`

## Request

- Base URL: `https://app.mandala.computer/api/v1`
- URL: `https://app.mandala.computer/api/v1/webhooks/{id}`
- Auth: HTTP bearer

One subscription, with its health: when the endpoint last accepted a delivery, when one last failed, the status of the newest attempt, and whether the platform has disabled it. Never the secret.

Requires the `viewer` role or higher.

## Path parameters

- `id` string, required

## Response `200`

The subscription.

- Webhook
  - `id` string, required: `whk-` and sixteen hex characters.
  - `url` string, required: Where deliveries are POSTed. `https://` only. The URL as the platform parsed it, which can differ in spelling from what you sent: the host lower-cased, a default port dropped, a bare origin ending in `/`.
  - `description` string, required: Free text, for your listing. Empty when you gave none.
  - `events` string[], required: The event types this subscription receives. **Empty means every type.** The vocabulary is the event socket’s (the computer’s `events_url`) less `file.changed`: `window.opened`, `window.closed`, `window.focused`, `window.blurred`, `clipboard.changed`, `process.exited`, `computer.idle`, `computer.ready`, `computer.started`, `computer.stopped`, `computer.suspended`.
  - `computers` string[], required: The computer ids this subscription receives events for. **Empty means every computer in scope.** Not checked against your computers when you set it — a subscription may name a computer you are about to create.
  - `enabled` boolean, required: Whether deliveries are made. Set `false` by the platform when an endpoint has failed for a day, or when the account moves to a plan without webhooks — see `disabled_reason`. Back to `true` by you with `PATCH`, which starts fresh, or, for `plan`, by the platform when you choose a plan again, which starts fresh too.
  - `disabled_reason` 'customer' | 'failing' | 'plan' | 'null', nullable, required: Why `enabled` is false: `customer` when you disabled it, `failing` when the platform did — a delivery ran out of attempts and nothing had been accepted for 24 hours, counted from the later of the last 2xx and when the subscription was last enabled — and `plan` when the account moved to a plan without webhooks. A `plan` subscription is enabled again, oldest first, as many as the plan allows, when the account chooses a plan that includes webhooks. `null` while enabled.
  - `disabled_at` string, nullable, required: RFC 3339 timestamp, or `null` while enabled.
  - `last_success_at` string, nullable, required: When the endpoint last answered 2xx to any delivery. `null` until it has.
  - `last_failure_at` string, nullable, required: When a delivery attempt last failed. `null` until one has.
  - `last_status` integer, nullable, required: The HTTP status of the newest attempt, whatever it was. `null` before any attempt, or when the newest got no answer.
  - `workspace_id` string: The workspace this subscription is confined to. Present only when it was created with a workspace-scoped API key; absent on an account-wide subscription.
  - `created_at` string, required: RFC 3339 timestamp.
  - `updated_at` string, required: RFC 3339 timestamp.

## Other responses

- `401`: Platform authentication required or refused: reason is missing, invalid, or revoked, with WWW-Authenticate: Bearer (invalid_token for invalid/revoked).
- `403`: The credential is recognized but its holder lacks the required role or membership, or the holder/account is suspended, or the holder has not verified their email address. An ordinary denial for too low a role may carry no `reason`. The email one carries none either, and its message begins `Verify your email before`: it answers a create, a clone of a computer or a snapshot, a new API key and a new SSH key, and is cleared by verifying the address in the dashboard. `reason: "revoked"` marks authority that is gone: a suspended account or a lost membership (refused as the request arrives, or if it happens while the request is in flight), or a role that was lowered while the request was in flight. The message identifies the refusal; replacing a valid key alone does not restore authority, and sending the same call again does not help. A suspended account may still make this read: a `403` here is about the credential or the person holding it, never the account’s suspension.
- `404`: No such resource in your scope — a computer, snapshot, secret, webhook, SSH key, API key, workspace, operation and so on — or no such endpoint; a confirmed missing guest file is no such file in the guest.
- `405`: This public path exists but does not accept that method. Allow lists only its public methods, with HEAD for GET and metadata OPTIONS.
- `429`: You are asking faster than your plan allows. `Retry-After` says how many seconds to wait, and every metered response — anything past authentication and the re-check that your credential’s authority still holds — carries `RateLimit-Remaining`, so you do not have to be refused to find out. A `401`, a `403` from that re-check, an `OPTIONS` answer and an unexpected `500` carry none. The budget is spent in proportion to what a call costs rather than per request. What a call costs, in budget units, by kind (each operation’s exact figure is its `x-rate-cost` in the OpenAPI document): 1 to read one thing; 5 for a listing that spans the fleet, and 5 for a call into a running guest such as a screenshot or an exec; 10 for a power change and 10 to move file bytes; 25 for `GET /usage`, `GET /credits`, creating a public URL, and creating, rotating or testing a webhook; 50 to capture a snapshot; 100 to create, clone or restore a computer, and 100 to start an agent run, whose actions are then charged as they happen. The account-wide budget, as what an idle caller may spend at once and what refills each minute: No plan 1200 at once and 1200 a minute; Solo 4800 at once and 4800 a minute; Studio 12000 at once and 12000 a minute; Swarm 21600 at once and 21600 a minute. A single API key gets half of either. A `401` for a missing or unusable credential costs nothing: it is refused before anything is metered. A few refusals at the door cost one unit: a `403` because the role is too low or the route refuses an API key confined to a workspace, a `404` for a path that matches nothing, a `405`, and an `Idempotency-Key` answered from its stored result or still in progress. Everything else is charged in full when it is admitted, before it is carried out, so a refusal after that has spent the whole cost: a `400`, `402` or `409` from the route, a `403` its handler sends (on most routes, a suspended account included), and a model provider’s `401` on an agent run. The budget belongs to the account and is shared across everything on it, and any single API key may spend at most half of it. `RateLimit-Limit` is whichever of those two is binding on the request that carried it — usually the per-key half, and the account-wide figure when other keys have already spent more of it than this one has. All three `RateLimit-*` headers describe the same one, so `limit` minus `remaining` is what has been spent against it. A few `429`s are not about this budget, say so in their message, and can carry no `Retry-After`: a model provider’s rate limit relayed on an agent run. The cap on forks of one snapshot waiting for their secrets sends its own bounded expiry-based `Retry-After` with `reason: "contention"` (see `POST /snapshots/{id}/clone`).
- `500`: The application could not finish this: an unexpected exception, a build that broke, or a storage fault. Application refusals carry the request correlation ID; unexpected internal details are not returned.
