Integrations

Connect Gratias to your group's tools.

A hotel needs no connection to its systems to use Gratias. This page is for groups that want the thank-you inside their own app, and for vendors of hotel management (PMS) or payroll software. Two entry points exist today.

The integration code carries only the key prefix, never its secret.

Two entry points, and keys. A hotel needs none of them: they serve groups and software vendors.

The embeddable page

The hotel's thank-you journey opens in a frame served by Gratias, within the group's app. The same amounts, the same payment, the same styling as the service card.

Origins
Only origins on a key's allowlist can display the page. Any other origin gets a polite refusal, without the hotel's name.
Funds
The host app never touches the funds, and receives no amount, no staff member and no balance.
Context
A context call returns the allowed origin and a suggested framing policy.

The tax classification API

For a payroll software vendor, or a group's payroll team. The caller describes a month, and the engine answers with the rule that applies. It reads only what the caller sends it.

What you send
A country among the seven modelled, a year, a month, a base salary and the month's total thanks.
What you get back
The nature of the regime, the rule code, the legal reference and a notice that this is not advice.

The Gratias team creates the keys with you and registers your origins. Your group can also open a trial space for one of its hotels, with no real payment.

Groups

The head-office console reads the group's hotels, each in its own currency, without ever showing a person.
