I want to give my guests a fun, airline-style way to bid for room upgrades. The site is WordPress, all bookings live in Beds24, and payments run through Stripe. Here’s the complete flow I need built: A guest clicks a unique URL that already contains their Beds24 booking ID and e-mail. Your code calls the Beds24 API, pulls back the reservation details (name, original room type, dates) and presents a clean, mobile-friendly slider interface. As the slider moves, a “Bid Strength” meter changes visually so the guest sees how strong their offer is; the artwork is fixed so you don’t have to build a design editor for it. When the guest submits the offer you take card details with Stripe, create an authorisation only, and park the charge. All bids drop into a simple back-office screen where I can approve or decline them one by one—manual approval only, no automation. If I hit Approve, two things must happen instantly: • the authorisation is captured in Stripe for the bid amount • the room category in the original Beds24 booking is updated via API Regardless of the decision, the guest receives a branded e-mail confirmation (approved or rejected). No SMS or in-app alerts needed. Tech stack is PHP/WordPress with JavaScript for the interactive UI. Please show past projects where you combined third-party APIs (Stripe, property-management, travel, etc.) with a custom interface. Clean, well-commented code, security best practices and a short hand-off document are part of the deliverable. Her er det opdaterede tillæg til din freelancer, hvor jeg har fjernet alle emojis og præciseret kravene til produktstyring og de to forskellige købsmuligheder. ADDENDUM: PRODUCT MANAGEMENT AND PAYMENT LOGIC 1. Dual-Mode Product Setup The system must allow the admin to create products with two distinct purchase flows: Bidding Mode (Upgrades): Admin sets a minimum and maximum price. The guest uses a slider to place a bid. This requires Stripe Authorization to hold funds without immediate capture. Instant Purchase Mode (Add-ons): For fixed-price products such as airport transfers, breakfast, or late check-out. This must trigger an immediate Stripe Capture for instant payment. 2. Dynamic Bid and Price Control Bid Increments: Ability to set specific increments for bids (e.g., bids must increase or decrease by 100 THB). Visual Feedback: The visual meter must be tied to the specific price range defined in the backend for each individual product. Direct Payment: For Instant Purchase products, the system must bypass the bidding logic and go directly to a fixed-price checkout. 3. Integration and Framework Base Engine: You may use the Ultimate WordPress Auction Plugin as the underlying engine, but the frontend must be fully customized to match the slider UI seen at [login to view URL] Automated Data Entry: The system must bypass standard user registration. It must automatically pull and display Guest Name, Email, and Booking ID from the Beds24 API based on the unique URL parameters provided in the marketing email. 4. Beds24 and Stripe Synchronization Instant Sales: Upon successful payment for a fixed-price product, the system must automatically post the charge and product name to the Info or Invoice tab in the corresponding Beds24 booking. Successful Bids: Upon manual approval of a bid in the backend, the system must trigger the final charge in Stripe and update the Room Category or Room ID directly in Beds24 via the API.

I can develop a WordPress-based room upgrade bidding system where guests receive a unique URL containing their Beds24 booking ID and email and the system automatically pulls reservation details via the Beds24 API and presents a slider interface with a dynamic bid strength visual meter. The solution will support two product modes: bidding mode for room upgrades with configurable min/max price and bid increments, using Stripe authorization to place a temporary hold and instant purchase mode for fixed-price add-ons with immediate Stripe capture. All submitted bids will appear in a secure admin back-office panel where you can manually approve or decline each request. On approval, the system will instantly capture the Stripe authorization and update the room category in Beds24 via API; on decline, no capture will occur. Regardless of the outcome, guests will automatically receive branded email confirmations. Best regards, Shawana

Hi, This is Elias from Miami. I checked your project description and understand you’re looking to create a fun bidding system for hotel room upgrades, similar to airline upgrades, using WordPress. This sounds like a unique way to enhance guest experience! I've built similar systems in the past, so I'm familiar with the technical challenges involved in integrating bidding features into existing platforms. I can help you design a seamless user experience while ensuring secure payment processing through Stripe. I’d love to discuss the details and suggest the best technical approach. I have a few questions to get a better understanding: Q1 – What specific user roles do you envision for guests and hotel staff? Q2 – Are there any existing systems you want to integrate with, like a booking engine? Q3 – What types of payment methods do you want to support besides Stripe? Looking forward to hearing from you.

This looks like a great fit, I will build the dual-mode upgrade/add-on system — Beds24 booking pull via unique URL, slider bidding with visual strength meter, fixed-price instant checkout, and the manual approval back-office screen with Stripe capture and Beds24 room sync on approve. For the Stripe flow, I will structure auth-only and instant-capture as separate payment intents determined by product type at creation time. This keeps the logic clean and ensures declined auths never accidentally capture, while instant purchases settle immediately. Questions: 1) Are bid increments always in THB, or do you need multi-currency support tied to the Beds24 booking? 2) For instant-purchase items, should the Beds24 invoice update include a line-item breakdown or just the total charge? Looking forward to potentially working together. Thanks, Kamran

Dear Client, I understand you want a hotel upgrade bidding system on WordPress, pulling Beds24 booking data via API, with a mobile-friendly slider UI showing a Bid Strength meter, Stripe authorization for bids, and a manual approval workflow with instant capture and Beds24 updates on approval. I will build a secure PHP/JS solution that calls Beds24 per unique URL, renders a clean, responsive interface, and routes payments through Stripe with an authorisation hold for bids and direct capture for instant purchases. The back office will present bids for manual approval, and upon approval I will capture the authorization and update Beds24 in real time, while all guests receive branded email confirmations. I will modularize the code, add thorough comments, and provide a concise hand-off document plus security best practices and a reference of past API-integrations. What are the exact Beds24 fields to map (e.g., room category IDs) for the upgrade and how should the approval events be logged in the admin back office (audit trail, timestamps, user actions)?

GPT-5.4 Hi, I understand you need a custom WordPress solution that connects unique guest links to Beds24, pulls booking details automatically, presents a polished bid slider with strength feedback, and supports two purchase paths: bid based upgrades with Stripe authorization only, and fixed price add ons with immediate payment. The system also needs a simple admin workflow where bids can be reviewed manually, then approved or declined with the correct Stripe and Beds24 actions plus branded email notifications. My approach would be to build this as a secure WordPress module with a custom JavaScript interface and API layer for Beds24 and Stripe. I would map each product to either bidding or instant purchase mode, enforce bid ranges and increments from the backend, prefill guest data from the booking link, and create an admin screen for review and decision handling. I would also make sure approved bids capture the held payment and update the booking room category, while add on purchases post the charge and product details into the correct Beds24 booking record. Before delivery, I would test link validation, booking retrieval, slider logic, authorization and capture flows, instant purchases, Beds24 updates, admin approvals, decline handling, email delivery, and edge cases such as expired cards, invalid links, and duplicate actions. Best, Justin

I can deliver this as a clean, production-ready WordPress solution by extending the Ultimate WordPress Auction Plugin for the bidding logic while fully custom-building the frontend slider UI and guest flow to match your requirements. I’ll integrate Beds24 via API to auto-fetch booking data from the unique URL (no login needed), and implement Stripe with separate flows for authorization (bids) and instant capture (fixed add-ons). The admin side will include a simple approval dashboard where you can accept or reject bids, triggering real-time Stripe capture and Beds24 room updates, while all transactions (including add-ons) are synced back to the booking record. The system will support bid increments, dynamic pricing ranges, and a visual strength meter tied to backend settings per product. I’ll follow security best practices (tokenized URLs, API validation, Stripe Elements, nonce protection), deliver clean, well-commented PHP/JS code, and include a short handover document so your team can manage products, approvals, and integrations بسهولة going forward.

Your bidding system will fail the moment a guest submits two bids within 60 seconds because Stripe authorizations don't stack - the second call will either overwrite the first hold or throw a duplicate idempotency error. I've seen this exact pattern break during soft launches when hotels send batch emails and 40 guests hit the system simultaneously. Before I architect the dual-mode logic, I need clarity on two things. First, what happens if a guest abandons a bid after you've placed the Stripe auth hold - are you manually voiding those every 7 days, or do you want automatic expiration with email notifications? Second, does Beds24 support partial invoice line items via API, or will I need to append upgrade charges as custom fields in the booking notes because their invoice endpoint is read-only? Here's the architectural approach: - PHP + WORDPRESS: Build a custom plugin that intercepts the unique URL, validates the Beds24 booking ID via API before rendering the interface, and handles session state to prevent duplicate submissions during network lag. - STRIPE AUTHORIZATION + CAPTURE: Implement idempotency keys tied to booking ID plus timestamp to prevent duplicate holds, then build a webhook listener that reconciles auth expirations with your approval queue so you're not manually chasing expired holds. - BEDS24 API: Use their PUT /bookings endpoint to update room category on approval and POST /invoice to append line items for instant-purchase add-ons, with retry logic because their API returns 503 errors during peak check-in hours. - JAVASCRIPT SLIDER UI: Clone the PlanB Rentals bid interface using range inputs with real-time AJAX validation against your min/max thresholds, plus a visual meter that maps bid strength to approval probability based on historical data you'll feed into the backend. - DUAL-MODE LOGIC: Route requests through a product-type classifier that either triggers the slider workflow with Stripe auth or bypasses to direct capture for fixed-price items, using the Ultimate Auction Plugin's hooks but stripping out 90% of its frontend bloat. I've integrated Stripe with 3 property-management systems where authorization timing was critical - one client was losing 12% of bids to expired holds before I rebuilt their queue. Let's schedule a 15-minute call to walk through your Beds24 API credentials and confirm whether their invoice structure supports what you need, because if it doesn't we'll architect a workaround now rather than discover it during UAT.
