# Take over a schedule

POST

/v1/schedules/{triggerId}/owner

```sh
curl --request POST \
  --url https://example.com/v1/schedules/2489E9AD-2EE2-8E00-8EC9-32D5F69181C0/owner \
  --header 'Authorization: Bearer <token>' \
  --header 'Content-Type: application/json' \
  --data '{ "runAsServiceAccountId": "example", "runAsProject": true }'
```

The caller becomes the schedule’s owner, so its runs act as the caller from the next run that starts. Needs `admin` on the schedule’s project (without an authorization store, a tenant-admin key) and `execute` on what it runs. For a schedule whose owner left or lost access, or to make one shared or personal. It’s the one way a schedule’s owner changes, audited as `trigger-owner-set`, naming the schedule’s version after it; a person it’s taken from is told, where the server tells owners. Name `runAsServiceAccountId` instead to make a service account the owner: that needs `act_as` on the account (a tenant admin’s), and the account must itself hold the access the schedule’s target needs. With an authorization store, that’s checked when the account is named: an account that can’t is refused (`409 trigger-owner-cannot-run-target`). Or name `runAsProject: true` to make the project’s own service account the owner, made the first time with the `editor` role on the project, so the schedule is shared and runs as the project. It runs only what the project’s editors can, and is checked the same way. The schedule keeps its `toolsAllowedUnattended`, now for the new owner’s runs; a body naming it is refused (change it with PATCH).

## Authorizations

- **[bearerAuth](https://docs.kindgi.com/v0.5.0/reference/api.md#bearerauth)**

## Parameters

### Path Parameters

**triggerId**

required

string format: uuid

TriggerId — the trigger id (a UUID).

### Header Parameters

**Idempotency-Key**

string

\>= 1 characters

Caller-supplied idempotency key, scoped to the caller: the same key from someone else in the workspace is their own request (from 0.1.5). Retries with the same key return the original response byte-identical (per `docs/API-ROUTE-CONVENTIONS.md` §3.1). A retry sent while the first request still runs is answered `409 idempotency-key-in-flight` with `Retry-After`, on a runtime whose store holds keys (from 0.1.5); retry after it, and you get the first request’s answer. An answer that carries a secret (a new API key or public run token, a session token, a generated signing secret) isn’t kept: a retry gets `409 idempotency-key-replay-withheld`, with the first request’s status and when it succeeded (from 0.1.5). A request whose key store can’t be read before it runs is answered `503 idempotency-store-unavailable` with `Retry-After`: nothing ran, so retry with the same key (from 0.3.0).

## Request Body

application/json

Who the trigger’s runs act as from now: for a trigger whose owner left, or to make one shared or personal. Absent, or an empty body: the caller takes it over (today’s behaviour). With `runAsServiceAccountId`: that service account becomes the owner. With `runAsProject`: the project’s own account does. A take-over keeps the trigger’s `toolsAllowedUnattended`: change that with PATCH.

object

**runAsServiceAccountId**

A service account the trigger’s runs act as (its owner), named by id, instead of the caller. Needs `act_as` on that account — a tenant admin holds it — and the account must itself hold what the trigger runs. With an authorization store, that’s checked when the account is named: an account that can’t is refused (`409 trigger-owner-cannot-run-target`). Not a project’s own account (409 `service-account-project-owned`: name it with `runAsProject`).

string

\>= 1 characters

**runAsProject**

`true`: the trigger’s runs act as its project’s own service account, made the first time with the `editor` role on the project, so it’s shared. It runs only what the project’s editors can. With an authorization store, that’s checked when it’s named: if it can’t run what the trigger runs, the request is refused (`409 trigger-owner-cannot-run-target`). Takes `admin` on the trigger’s project (without an authorization store, a tenant-admin key), not `act_as`. Not with `runAsServiceAccountId`, and not without a project (400). A runtime that can’t make the account answers 501 `trigger-operation-unsupported`. `false` or absent: as `runAsServiceAccountId` says.

boolean

##### Examplegenerated

```json
{
  "runAsServiceAccountId": "example",
  "runAsProject": true
}
```

## Responses

### 200

The schedule, with its new owner.

application/json

A schedule: what it runs (a flow at a version, or an agent), when (a cron expression in a timezone), as whom (its owner), and what it does after a gap or while a run is still going.

object

**scheduleId**

required

Domain-friendly alias for `triggerId` — the trigger id (a UUID). Use interchangeably in admin URLs.

string

**triggerId**

required

string

**flowId**

A schedule that runs a flow: the flow, at `flowVersion`.

string

\>= 1 characters

**flowVersion**

string

\>= 1 characters

**agentId**

A schedule that runs an agent: the agent, at `agentVersion`, else its version pinned for the schedule’s project (else the latest), as a run that names none.

string

\>= 1 characters

**agentVersion**

string

\>= 1 characters

**improve**

A schedule that starts Improve runs: on this agent, in this project (the schedule’s), when the project has enough new corrections sorted to improve since its last Improve run (`input`: how many, whose, and what a run and the month may cost). An agent and project have one at most.

object

**agentId**

required

string

\>= 1 characters

**projectId**

The schedule’s own project. Absent from older servers, and on a schedule registered for a workspace or an org before Improve schedules worked in a project: its fires are refused until its target is saved with the schedule’s project.

string format: uuid

**projectId**

The schedule’s project: its runs are this project’s.

string format: uuid

**owner**

Who its runs act as. A person: a personal trigger, which only they or a project admin change. A service account: a shared trigger. Only a take-over (`POST …/owner`) changes it. Checked again at every fire.

object

**kind**

required

string

Allowed values: user service

**id**

required

string

**displayName**

The owner’s name at the time of the response: the person’s display name, or the service account’s name. Absent when it can’t be read (no directory, a removed account) and from a runtime before Kindgi 0.1.6: show the id then.

string

**isProjectAccount**

Set when the owner is the trigger’s project’s own service account (`runAsProject`): the trigger is shared, and runs as the project. Show it as “This project”. Absent otherwise.

boolean

**cronExpression**

required

5- or 6-field cron expression (croner-compatible). 6-field enables second precision.

string

\>= 1 characters

**timezone**

IANA timezone (e.g. `UTC`, `America/New_York`). Absent → `UTC`.

string

**input**

Static input handed to the run on every fire. Absent → `{}`.

**catchUp**

After a gap (the runtime was down, or a fire is later than `startingDeadlineSeconds`): `latest` runs once, for the latest missed occurrence, and its fire says how many it missed; `skip` drops the missed occurrences. Never a run per missed occurrence. A workspace’s suspension isn’t caught up either way: once the workspace is restored, a schedule that’s on fires next at its first occurrence after the restore.

string

Allowed values: latest skip

**overlap**

When an occurrence comes while the previous run of this schedule is still running: `skip` records the fire as skipped; `allow` starts another run.

string

Allowed values: skip allow

**startingDeadlineSeconds**

How late a fire may start and still count as on time; past it, `catchUp` applies.

integer

\>= 1

**label**

required

string | null

**status**

required

Lifecycle status. Only `active` triggers fire. Tombstoned rows are excluded from every read path.

string

Allowed values: active paused

**statusReason**

Why the runtime paused it: repeated fires that were refused (the owner lost access) or failed. Skipped fires (an overlap, an erasure in progress) never count. For an Improve schedule, `owner-lost-publish` pauses it at once: its owner no longer has `publish` on the agent. Saving it with a new owner resumes it.

string

**pausedUntil**

For an Improve schedule whose month’s Improve runs have reached its monthly cap (`input.monthCapUsd`): when it starts again by itself, the 1st of next month (UTC). It stays `active`, and its fires until then are `skipped`. Absent otherwise.

string format: date-time

**pausedReason**

Why it waits until `pausedUntil`: its month’s cap.

string

Allowed values: month-cap

**version**

The trigger’s newest version (`GET …/versions`): one more for each change to what it runs, when, as whom or with what. Absent until its first version.

integer

\>= 1

**toolsAllowedUnattended**

The tools whose calls in this schedule’s runs don’t wait for a person’s yes, though a tool asks for one in a run no person started (`needsApprovalWhenUnattended`). Absent: none. Each tool by its id, with no wildcard or pattern, and only tools this trigger’s flow or agent calls. It lifts only that wait: the workspace’s approval rules, the agent’s own rules, the permission check (as the trigger’s owner) and the tool’s own limits all still apply.

Array\<string>

<= 100 items unique items

**nextFireAt**

required

Wall-clock time of the next scheduled fire. `null` on paused rows if the cron scheduler never re-armed.

string | null format: date-time

**upcoming**

The next occurrences, when the request asked for them (`?upcoming=N`).

Array\<string>

**lastFiredAt**

required

string | null format: date-time

**createdAt**

### 409

`runAsServiceAccountId` names an unregistered account (`service-account-unregistered`), a project’s own account (`service-account-project-owned`: name it with `runAsProject`), or one that can’t run what the schedule runs (`trigger-owner-cannot-run-target`). Or, with `runAsProject`, the project’s own account can’t run what the schedule runs either (`trigger-owner-cannot-run-target`; the account stays, for the next `runAsProject`), or an active account someone made already has the project account’s name, `project-<projectId>` (`service-account-name-taken`: a tenant admin can unregister it). Or an idempotency conflict.
