# Modules

Browse every PHPTRAVELS module with setup guides: stays, flights, tours, cars, visa, Umrah, ferries and eSIM, plus supplier APIs like Sabre and Hotelbeds.

### How PHPTRAVELS modules work

PHPTRAVELS is built from modules. Each module is a booking engine with its own search, results, booking flow, voucher and back office, and you switch on only the ones you sell. A module can run on your own inventory (products, rates and availability you load yourself) or on live supplier APIs, or both at once in the same search.

Supplier APIs need your **own contract and credentials** with each supplier. PHPTRAVELS provides the connection and the booking flow; it does not supply inventory.

### Turning a module on

1. Log in to your admin panel at `yourdomain.com/admin`.
2. Open **Settings > Modules** (`/admin/settings/modules`). Every module and supplier is listed there.
3. Open a module, enable it on the **General** tab and set its currency.
4. For live suppliers, enter your API credentials on the **Credentials** tab and use **Test** where available. Keep **Dev mode** on development until a test booking works.
5. Set B2C and B2B margins on the **Markup** tab.

### Before you go live

* Run a test search and booking for each module you enable.
* Check vouchers and invoices in the admin and in the customer email.
* Confirm that supplier references are saved on each booking.

The current list of supported suppliers is on the [integrations page](https://phptravels.com/integrations). A supplier that is not listed can be added as custom development.
