Everything the app does, it does through a REST API you can call yourself.

Base URL and auth

https://api.atwork.so

Routes are versioned, so paths start with /v1/. Authenticate with a bearer token on every request:

Authorization: Bearer YOUR_TOKEN

Create a token under Profile settings → API tokens. It carries your access — see API tokens.

Sheets

Purpose	Call
List sheets	`GET /v1/sheets`
Get one sheet, with its attributes	`GET /v1/sheets/:sheetId`
Create a sheet	`POST /v1/sheets`
The available field types	`GET /v1/sheets/data-types`

Fetching a sheet returns its attributes — that is where you find the field ids and codes you need for everything else.

Items

Purpose	Call
Read items	`POST /v1/sheets/:sheetId/get-items`
Create an item	`POST /v1/sheets/:sheetId/items`
Update an item	`PATCH /v1/sheets/:sheetId/items/:itemId`
Delete an item	`DELETE /v1/sheets/:sheetId/items/:itemId`
Duplicate items	`POST /v1/sheets/:sheetId/items/duplicate`

Reading items is a POST, not a GET — the filter, sort and pagination go in the request body, which would not fit sensibly in a query string. That surprises people, so it is worth stating plainly.

Fields and views

Purpose	Call
Add a field	`POST /v1/sheets/:sheetId/attributes`
Update a field	`PATCH /v1/sheets/:sheetId/attributes/:attrId`
Add an option to a select field	`POST /v1/sheets/attribute-options/:attrId`
Create a view	`POST /v1/sheets/:sheetId/view`

Other areas

The same pattern covers the rest of the product — /v1/agents, /v1/calendars, /v1/dashboards, /v1/notifications, /v1/page, /v1/integrations, /v1/availability and more.

Practical notes

A token acts as you. Anything you can see and change, it can.
Read a sheet first to learn its attribute codes rather than hard-coding guesses; codes are generated and are not the display names.
Page through large sheets using the filter body instead of pulling everything.
Be considerate with volume. Some public endpoints are rate limited; hammering the API in a loop is a good way to get an unhappy response.
