API keys
Create API keys in QUANTICAL.ERP for automations such as n8n - permissions per endpoint, expiry and usage limit, authentication via x-api-key and the endpoints of the automation API.
With an API key external tools read data from QUANTICAL.ERP without anyone signing in: a weekly report in n8n, an analysis in Excel, a reconciliation with payroll. You manage the keys under Administration
API Keys.

Create a key
Create API Key opens the dialog. The Name later tells what the key is for, the Prefix makes it recognisable in logs. Expires In limits the lifetime from 30 days to one year, or never. Maximum Uses deactivates the key after a fixed number of calls. Under Endpoint Permissions you choose which data the key may read, All endpoints or individual ones.

Copy the key
After creation QUANTICAL.ERP shows the key exactly once. Copy it into your tool now, afterwards only the Key Preview remains visible. If it gets lost, create a new one and delete the old one.

Using the key
Every request carries the key in the x-api-key header. The built-in
documentation describes the endpoints with parameters, example calls
and responses and can be copied as Markdown, for example to hand it
to a developer or an AI assistant.
| Endpoint | Returns |
|---|---|
/api/automation | Status of the key |
/api/automation/weekly-booking-report | Booked and missing hours of all active employees per calendar week |
/api/automation/time-entries | Time entries, filterable by project, employee, client and period |
/api/automation/projects | Projects, on request with staffing and rates |
/api/automation/employees | Employee master data without sensitive fields |
/api/automation/vacation-requests | Vacation requests of any status |

A key reads with the rights of an owner. Issue a separate key per tool with only the permissions needed and delete it as soon as the tool no longer needs it.
