Summary

This Beta release delivers four fixes addressing error handling and data accuracy improvements across the API. Partners are encouraged to test the affected endpoints ahead of the Live release.

Fixes & Improvements

Webhooks — PUT /webhooks/{id} Returns 500 for Inactive Webhooks

Calling PUT /webhooks/{id} with an inactive or non-existent webhook ID was incorrectly returning a 500 Internal Server Error instead of a meaningful error response. This has been fixed. The endpoint now returns 404 Not Found in these cases, allowing integrators to handle the response appropriately.

• Endpoint affected: PUT /webhooks/{id}

Transactions — Credit Card Fee Rounding via POST /transactions/receipt

When a credit card fee was submitted via POST /transactions/receipt with more than 2 decimal places (e.g. 0.9608), the value was stored as-is in RMS. This caused a rounding mismatch on the account balance, which prevented users from processing valid refunds — the system would reject a refund that appeared within the available credit balance because the stored fee value didn't align to standard 2-decimal currency precision.

This has been fixed. Credit card fee values are now rounded to 2 decimal places at the point of storage, ensuring account balances are calculated correctly and refunds can be processed without errors.

This fix affects any integration using POST /transactions/receipt that submits credit card fee values with more than 2 decimal places.

• Endpoint affected: POST /transactions/receipt

Reservations — Discounts with Validation Rules Return 204 in POST /reservations/discounts/search

POST /reservations/discounts/search was returning 204 No Content for discounts that had validation rules applied (e.g. date made ranges, stay date ranges), even when the search criteria matched those rules. Discounts without validation rules were unaffected.

This has been fixed. The endpoint now returns all eligible discounts, including those with validation options configured, provided the request parameters fall within the defined rules.

• Endpoint affected: POST /reservations/discounts/search

Reports — POST /reports/auditTrail Returns 500 Internal Server Error

Calling POST /reports/auditTrail with an empty glCodeIds array was causing a 500 Internal Server Error. This affected all requests regardless of other parameters supplied.

This has been fixed. The endpoint now returns audit trail data without filtering by GL code when glCodeIds is passed as an empty array.

• Endpoint affected: POST /reports/auditTrail

IBE+ has been upgraded to support 3D Secure (3DS) for Stripe payments, along with an improvement to how payment details are captured at checkout.

Card entry fields are now hosted directly by Stripe, making them clearer, better labelled, and more visually distinct - reducing confusion at the payment step and improving booking completion.

Where required by a guest's bank, a quick verification step will now be triggered during checkout to authenticate the payment. This happens automatically and is designed to be as frictionless as possible for the guest, while significantly improving fraud protection and reducing chargeback risk for properties.

Properties can now control whether email and SMS marketing opt-in options are displayed to guests during the IBE+ checkout flow.

When enabled in Field Maintenance, guests will see channel-specific checkboxes on the guest details step — allowing them to independently opt in or out of email marketing, SMS marketing, or both. Only the channels that have been enabled in 9+ will be displayed, so guests are never shown options that aren't relevant to the property.

If a guest opts in, their preferences are written back to the guest record in 9+. If a guest opts out, that is recorded accordingly. If a property chooses not to expose these options at all, no value is set and the property's default marketing opt-out setting will apply via the sweeper as usual.

Marketing consent is always optional and checkboxes are never pre-selected, keeping the experience transparent and compliant.

IBE+ now includes cookie consent support, helping properties stay compliant with privacy regulations such as GDPR and the UK ePrivacy rules.

A cookie consent banner will be displayed to guests when required, based on the location of the property — not the guest's location. So if your property is in the UK or EU, guests will be prompted to manage their cookie preferences regardless of where they are browsing from.

If you already use your own Google Tag Manager (GTM) setup and cookie banner on your website, IBE+ will display your banner and suppress the default RMS one — so guests see a single, consistent experience across your site and booking engine. If you don't have your own, the RMS default banner will appear where required.

Consent choices and attribution (such as UTM parameters) are also preserved as guests move from your website into the booking engine, so you won't lose analytics data or re-prompt guests unnecessarily.

IBE+ now supports day use categories, allowing guests to search for and book daily-rate options — such as car parks — directly through the booking engine.

When a guest searches with the same arrival and departure date, available day use categories will be returned and displayed alongside their pricing. Bookings are created as standard reservations in 9+, with inventory protected to prevent overbooking — even under high volumes of concurrent booking attempts.

At this stage, day use categories display instead of accommodation categories, not alongside them. Properties with categories configured as "booked by day" in 9+ will have these surfaced automatically when a same-day search is made.

IBE+ now supports BIG4 Holiday Parks memberships. Guests can enter their membership number during the booking process to automatically unlock eligible member discounts and benefits — with clear confirmation of savings displayed throughout the booking journey.

Membership details persist across all booking steps, and any invalid or expired membership numbers will prompt a clear, helpful error message so guests are never left guessing.

IBE+ now supports G'Day Parks memberships. Guests can enter their membership number during the booking process to automatically unlock eligible member discounts and benefits - with clear confirmation of savings displayed at every step of the journey.

Membership details persist across all booking steps, and any invalid or expired membership numbers will prompt a clear, helpful error message. It's worth noting that memberships sit within the discount priority order - if a promo code or auto-discount applies, that will take precedence, but the membership number remains valid and will apply if no higher-priority discount is in play.

Previously, when a Last Minute or Advanced Purchase restriction was configured at the rate type level, IBE+ would return a blank page with no categories and no messaging — leaving guests with no indication of why nothing was showing.

Categories will now always be returned and displayed, even when a restriction applies. Where a rate restriction means a category is not bookable for the selected dates, it will appear with a No Availability banner so guests understand why they cannot book rather than seeing a blank screen.

Where multiple rates are assigned and only some have restrictions, the unrestricted rates and categories will continue to display as normal — only the restricted rate will be excluded from the results.

Two error messages shown to guests during the booking process have been updated to be clearer and more helpful.

Previously, when a guest attempted to add more bookings than a property allows, the error message was unclear and could cause confusion. The message will now read: "Sorry, you've exceeded the maximum number of bookings this property allows. Please adjust your selection to continue." This covers both properties that don't allow group bookings at all, and those that allow group bookings up to a configured maximum.

Similarly, when a guest searches for a group size that exceeds the capacity of a single unit, the message has been updated to read: "Your group size exceeds the maximum capacity of a single unit. Please select multiple units to accommodate your group." This replaces previous wording that referenced "rooms" specifically, making the message applicable across all property types — including sites, cabins, and other accommodation formats.

Resolved an issue where reservations created through IBE+ were being assigned check-in and check-out times from the property level, even when specific times had been configured at the category level.

IBE+ will now correctly honour category-level times where they have been set, falling back to property-level times only when no category-level configuration exists. This applies to both standard night bookings and day use bookings.
