Hello WebSite X5 Community!

I hope everyone is having a great day.

I am managing a premium mobile wellness and Busan Outcall Massage service in South Korea. Unlike traditional local spas, our business model strictly caters to English-speaking expats, foreign tourists (mostly from the US and Singapore), and VIP business travelers staying in 5-star hotels.

WebSite X5 has been absolutely fantastic for building our brand's elegant online presence. However, as our international clientele grows, our scheduling and payment needs are becoming highly specific.

I am looking for the best practices or plugin recommendations to achieve the following:

1. Multi-Currency Payment Gateway: Integration with Stripe or PayPal that easily processes international credit cards without strict local authentication.

2. WhatsApp API Integration: A fast, floating widget that allows clients to instantly reach our dispatch team, as 24/7 real-time communication is crucial for hotel deliveries.

3. Time-Zone Friendly Booking: An automated scheduling system that sends confirmations in English, adapting to the client's device time zone.

4. Mobile-First Speed: Optimization tips to ensure the booking form loads instantly on mobile devices, even on hotel Wi-Fi.

Has anyone successfully built a similar premium concierge or wellness booking flow using WebSite X5? Any widget recommendations or coding tips would be highly appreciated!

Thank you in advance for your valuable insights.

Best regards,
