Data model

Feedback items

Incoming feedback on a grant - from uni TTO, programme officer, mentor, or a self-note. The body field carries the raw text; extracted markup points live in feedback_point.

Model name: feedback_item

Endpoints: 5

Max page size: 500

Fields

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

Field	Type	Constraints
who	`string`	max length`200`
body	`string`	max length`50000`
status	`enum`	enum`open \| extracting \| applied \| ignored`
unread	`bool`	-
urgent	`bool`	-
subject	`string`	max length`300`
due_date	`string`	max length`32`
grant_id	`string`	max length`64`ref →`grant`
source_type	`enum`	enum`uni \| ptj \| mentor \| self \| external`
file_blob_id	`string`	max length`64`

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
who	string
body	string
status	enum
unread	bool
urgent	bool
subject	string
due_date	string
grant_id	string
source_type	enum
file_blob_id	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/feedback_itemfeedback_item: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://granttool.de/xapi2/data/feedback_item?limit=20"

GET/xapi2/data/feedback_item/{id}feedback_item: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://granttool.de/xapi2/data/feedback_item/OBJECT_ID

POST/xapi2/data/feedback_itemfeedback_item: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://granttool.de/xapi2/data/feedback_item \
     -d '{"name": "…"}'

PATCH/xapi2/data/feedback_item/{id}feedback_item: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://granttool.de/xapi2/data/feedback_item/OBJECT_ID \
     -d '{"name": "…"}'

DELETE/xapi2/data/feedback_item/{id}feedback_item: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://granttool.de/xapi2/data/feedback_item/OBJECT_ID

Use in CLI

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

grantscli feedback_item list --limit 5
grantscli feedback_item get <id>
grantscli feedback_item create --grant-id "Hello"
grantscli feedback_item upsert --unique grant_id --csv items.csv
grantscli feedback_item schema   # fields & limits
