Inside Rentlio Booking Engine settings there are multiple payment methods you can choose for guests booking accommodation on your website.

Credit Card

If you choose the Credit Card option, the guest is required to enter their credit card details when making a reservation.
However, it’s important to note that the card is not automatically verified — the system only collects the card information and stores it with the reservation.
The reservation is charged using your own POS terminal.
To access the card details, you need to enter a PIN within the reservation interface in Rentlio. You can find instructions for setting up your PIN here.
Important: Card details are available for up to 4 days after the guest's check-out, so make sure to process the payment within that time frame.

Bank Transfer

If the guest selects Bank Transfer, they will independently transfer the payment amount to your bank account after making the reservation.
Until the payment is received, the reservation will have an “option” status and will not be automatically confirmed.
Once the payment is received on the account (entered in the Rentlio Booking Engine settings), you manually confirm the reservation on the calendar and issue an advanced payment invoice if needed.

Payment Gateway

If you are using an integrated online card payment system (e.g., Monri, Stripe, M2Pay, or another provider listed in the Rentlio interface), you can charge the guest’s card in advance — either partially or in full.

The method and timing of the charge are defined in the settings of the Rentlio Booking Engine, based on the policies you have set.

Monri

You need to be registered to Monri (provide RBE link for the registration) and use Your API key and Authenticity token.

Save settings and check-mark Monri as payment method.

The guest will add his credit card details on the final step to confirm his booking on Your Web page; a Monri pop-up window will open so he can accept all details and complete the booking process.

Reservation will appear on Your Rentlio calendar, with an option to charge the reservation amount manually.

Stripe

For Stripe the process is the same as above explained, simply add Your Secret API key and Published API key on Rentlio Booking Engine settings.

Once activated, the payment method can be selected and used on RBE.

On Your Rentlio calendar, You will be able to charge the card:

M2Pay

Once you receive the Booking Engine, PMS merchant ID and signature key from M2Pay you need to insert those values under the Booking engine settings in Payments.
