Inntopia + Shift4 Payments®

The Inntopia + Shift4 Payments integration uses Access Token credentials to securely process credit card information. In addition, it supports subsequent credit card charges on the same card to facilitate deposit schedules typically used in the travel industry.

As an online user or agent works through the checkout path, they are required to enter credit card information on the Billing Info screen. When a credit card is entered into the Inntopia system (either online in eComm or through Inntopia CRS), Inntopia initially validates the card and then makes a call to Shift4 to tokenize the credit card number. The tokenized credit card number is then stored in the Inntopia database.

Note: Credit Card Authorization Service Cutoff Time: Credit card transactions are recorded as of the local date and time for all CRS users. Change the time specified as the daily batch cutoff with your credit card authorization service.

  • Shift4 must be used with Inntopia's reseller-collect payment model.
  • One-time charges
  • Subsequent charges via a Deposit Schedule, through the payment queue
  • Tokenization
  • Card Verification Values (CVV) or Card Verification Digits (CVD)
  • Address Verification Values (AVS)
  • Shift4 provides a combination of processor AND gateway services.
  • i4Go® and Access Token are the Shift4 products that Inntopia communicates with via the integration.
  • Inntopia utilizes Shift4's tokens, as these can be re-used for subsequent transactions.
  • Shift4 does not allow the re-display of a plain-text card number once it is tokenized, but Inntopia can process subsequent charges against the tokenized card.
  • In the Inntopia application, Shift4/Inntopia displays the last four digits of a credit card as the first four digits.
  • Inntopia is certified to support one-pass Address Verification Services (AVS). Partners work directly with Shift4 to define the specific codes used during AVS. Shift4 performs the AVS check and then sends back a Pass or Fail message to Inntopia.
  • Shift4 has certified Inntopia for both CRS/agent-initiated and online credit card transactions.

Inntopia offers the ability to collect and submit Card Verification Value (CVV) codes for use with Shift4. Resellers using the Shift4 payment gateway can submit a request to Inntopia Partner Services to activate fields in Inntopia CRS and Inntopia eComm to collect, view, and submit the CVV code for credit-card transactions.

Note: Partners should review the CVV options in their Shift4 account prior to activating this feature in Inntopia to ensure they are collecting/validating CVV in all scenarios that will give the partner and the guest the best experience.

To learn more about enabling this feature for your Inntopia account, contact Inntopia Partner Services.

Address Verification Service (AVS) is a part of credit card authorization that aids in preventing fraudulent online transactions by verifying the billing address submitted by a customer with the billing address on file with the credit card company. Once submitted, the credit card company replies to the payment gateway with a response code indicating whether or not the billing address, and subsequently card ownership, is verified as a match.

  • Tokenized and untokenized credit card numbers cannot be passed to third-party systems (PMS/POS).
  • Shift4 does not provide stand-alone, gateway-only services.
  • Independent refund on a card without a correlated charge.
  • Pre-authorization of the card for a subsequent capture transaction.
  • Pre-authorization completion (capture), or charging the card in a separate step.
  • Shift4 cannot be used with IBE V9 as the credit card number will not be tokenized.
  • Due to differences in the tokenization process, a CRS sales ID should not be used in eComm links provided to guests (i.e. for promotions). For any eComm links provided to guests, use the eComm sales ID.
