}Request cancellation
Requests cancellation and returns the current job object —
canceling (interruption takes effect at node/step boundaries),
canceled where the provider’s record already shows the interrupt, or
already-terminal. Idempotent: canceling a finished job is a no-op
returning the terminal state. On serverless, GPU seconds consumed
before the interrupt takes effect are still billed.

Authorization: Bearer <credential>. The credential is one of: an account-scoped API key (comfyui-…), accepted on Cloud and serverless; a Comfy Cloud session JWT; or an OAuth access token issued for the Comfy Cloud resource. Which kinds a given deployment accepts is deployment configuration — an API key always works on Cloud and serverless, and a deployment that does not accept JWT bearers answers 401 with a message saying so. Self-hosted accepts unauthenticated requests by default and can be configured with a static bearer token.

Current job state.
One execution of a workflow. Durable from creation until expires_at; outputs populates incrementally during execution.
"7f3d2c1b-9a8e-4d6f-b012-3c4d5e6f7a8b"
Lifecycle: queued → running → succeeded | failed | expired; a cancel request, or the deletion of the deployment the job is running on, moves running → canceling → canceled. Terminal states: succeeded, canceled, failed, expired.
queued, running, succeeded, canceling, canceled, failed, expired Retention deadline — a platform property, not an API constant.
The latest progress snapshot; same data the SSE stream pushes.

Embedded follow-up links — follow these, don't build URLs. A link is either an absolute URL or a host-relative reference (leading /) that already includes any prefix the serving surface is mounted under (e.g. a serverless gateway's /deployment/{deployment_id}/api/v2). Clients MUST resolve a host-relative link against the request origin (scheme + authority), never against a configured base URL — joining it to a base URL that carries the same mount prefix duplicates the prefix.

Values are nullable (a metric not yet available — e.g. execution_ms before a job starts running — is null, not omitted); the example below is deliberately all-non-null purely to work around a Spectral/nimma lint-tooling crash on a literal null inside a schema example combined with additionalProperties.nullable: true — the schema itself is unchanged and still allows null values at runtime.

The deployment the job was sent to: the id in the address it was posted at, which stays the same when the deployment moves to another release. Absent on a surface that runs jobs on no deployment.
"dep-0f19a2b3c4d5"
The release of the deployment's build that ran the job, which can differ from the release the deployment runs now. Absent where the serving surface does not report it.
"7c1e9a40-3b2d-4f6a-9e81-0c5d2a7b4f13"
The version of the release in release_id, the number its build cut it as. Absent where the serving surface does not report it or could not look it up at the time of the answer.
x >= 13
The labels the job was submitted with, exactly as sent. Absent when it was sent with none.
