Data model

Cards

A work item on a board. Carries a status (1:1 with a board column), position for in-column ordering, plus priority, tags, assignee, and due_date. data.board_id must reference an owned board (or be blank for unsorted cards).

Model name: card

Endpoints: 5

Max page size: 200

Fields

Per-field validation rules. Values that violate any constraint are rejected with 400 before they reach the database.

Field	Type	Constraints
tags	`tags`	-
title	`string`	max length`200`
status	`string`	max length`64`
assignee	`string`	max length`64`
board_id	`string`	max length`64`ref →`board`ownedopt
due_date	`string`	max length`32`
position	`number`	-
priority	`enum`	enum`low \| medium \| high \| critical`
description	`string`	max length`4000`

Mutability

Which fields can you send, and when? Anything without a marker is server-managed - sending it isn't an error, it's silently ignored.

Create-only - read from POST body.Patchable - read from PATCH body.Server-managed - ignored on the body.

Field	Type	Create	Patch
tags	tags
title	string
status	string
assignee	string
board_id	string
due_date	string
position	number
priority	enum
description	string

Fields marked create-only but not patchable are immutable after creation. Server-managed fields include id, timestamps, ownership, and status.

Filtering & sorting

Combinable on list endpoints. Repeating a filter key produces an IN clause; prefixing a sort key with - reverses direction. Example: ?status=open&status=blocked&sort=-created_at.

Endpoints

Each endpoint below lists its HTTP method, path, and the PAT scope it needs. Code samples cover curl, JavaScript, TypeScript, Python, Rust, Java, and WebSocket.

GET/xapi2/data/cardcard:list

List objects

Returns a paginated list of objects you can read. Default page size is 20; pass ?limit= to change (capped per type). Use ?after=<id> for keyset pagination on created_at-sorted lists, or ?offset= for offset paging.

curl -H "Authorization: Bearer pat_…" \
     "https://qtssystem.com/xapi2/data/card?limit=20"

GET/xapi2/data/card/{id}card:read

Read one

Returns the object by id. 404 if it does not exist or you cannot read it (the two cases are intentionally conflated).

curl -H "Authorization: Bearer pat_…" \
     https://qtssystem.com/xapi2/data/card/OBJECT_ID

POST/xapi2/data/cardcard:create

Create

Creates a new object. Body is a flat JSON dict of field values. Server-side fields (id, timestamps, ownership) are filled automatically; only fields listed below as creatable are read from the body.

curl -H "Authorization: Bearer pat_…" \
     -H "Content-Type: application/json" \
     -X POST https://qtssystem.com/xapi2/data/card \
     -d '{"name": "…"}'

PATCH/xapi2/data/card/{id}card:update

Update

Partial update. Only fields included in the body are touched; everything else is preserved. Same allow-list as create, minus the fields that are immutable post-create.

curl -H "Authorization: Bearer pat_…" \
     -H "Content-Type: application/json" \
     -X PATCH https://qtssystem.com/xapi2/data/card/OBJECT_ID \
     -d '{"name": "…"}'

DELETE/xapi2/data/card/{id}card:delete

Delete

Removes the object. It vanishes from every default list immediately and stops being returned by read / list.

curl -H "Authorization: Bearer pat_…" \
     -X DELETE https://qtssystem.com/xapi2/data/card/OBJECT_ID

Use in CLI

The same endpoints are also exposed via the Production Board CLI. For scripts, CI, and bulk imports it's usually the faster path.

prodcli card list --limit 5
prodcli card get <id>
prodcli card create --title "Hello"
prodcli card upsert --unique title --csv items.csv
prodcli card schema   # fields & limits
