# A schedule's versions

GET

/v1/schedules/{triggerId}/versions

```sh
curl --request GET \
  --url 'https://example.com/v1/schedules/2489E9AD-2EE2-8E00-8EC9-32D5F69181C0/versions?limit=25' \
  --header 'Authorization: Bearer <token>'
```

Newest first: each version of the schedule, what it was from `createdAt` on, who made it (`createdBy`) and why (`cause`). Registering makes version 1, and each change makes the next (a PATCH that alters it, or a take-over to another owner): a PATCH that changes nothing makes none, nor do pausing, resuming or deleting. A version never changes once made. A fire’s run uses the newest when it starts, and keeps it whatever later edits make (the run’s `trigger.version`). A schedule from before versions has none until its next change or its first fire. The versions keep every input the schedule has had, so a secret pasted into its input stays in an earlier version after you edit it out: rotate it. Whoever can read the schedule can read its versions.

## Authorizations

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

## Parameters

### Path Parameters

**triggerId**

required

string format: uuid

TriggerId — the trigger id (a UUID).

### Query Parameters

**limit**

integer

default: 25 >= 1 <= 100

1..100. Default 25.

**cursor**

string

Where the previous page ended: its `nextCursor`, as it came. A runtime that seals cursors takes one only for the same list, filters and caller, within a day; otherwise `400 bad-input`, and the list starts again without it. Absent → first page.

## Responses

### 200

Page of versions, newest first.

application/json

Newest first.

object

**data**

required

Array\<object>

One version of a schedule: what it was from `createdAt` until the next. A fire’s run uses the newest when it starts, and keeps it.

object

**scheduleId**

required

The same id as `triggerId`.

string

**triggerId**

required

string

**version**

required

Counts from 1, one more for each version.

integer

\>= 1

**createdAt**

required

string format: date-time

**createdBy**

Who made the change, as audit records name an actor (`user:<id>`, `service_account:<id>`, …). Absent on a version the runtime made (`first-fire`, `unversioned-edit`, `pin`).

string

**cause**

required

What made the version: `register` (the trigger’s first), `edit` (a change to it), `owner` (a take-over to another owner), `first-fire` (the runtime’s, at the first fire of a trigger from before versions, or a mail trigger’s first look at its mailbox), `unversioned-edit` (the runtime’s, at a fire or a mail trigger’s look at its mailbox, or just before an edit or take-over, when the trigger’s definition isn’t its newest version’s, as when a release from before versions changed it during an upgrade) or `pin` (the runtime’s, when it fixed a mail trigger to the one connection it could use).

string

Allowed values: register edit owner first-fire unversioned-edit pin

**definition**

required

What a schedule’s version runs, when and as whom, as its record names them, and never its state (status, next or last fire). The versions keep every input the trigger has had, so a secret pasted into its input stays in an earlier version after you edit it out: rotate it.

object

**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**

required

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

string format: uuid

**owner**

required

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**

required

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**

required

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**

required

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

integer

\>= 1

**label**

required

string | null

**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.
