Five Core Pillars of a Greater Bay Area Ground Transport RFP
- 1. Single-Provider Multi-Border Coverage: Can the vendor cover Hong Kong local, Macau local, Hong Kong ⇄ Macau, Hong Kong ⇄ Shenzhen/Guangzhou/Zhuhai/Dongguan, and Macau ⇄ Guangdong under one master agreement?
- 2. Commercial Licensing & Cross-Border Compliance: Does every dispatched MPV carry valid commercial hire-car permits and dual-plate quotas, strictly excluding non-commercial private cars?
- 3. Deterministic All-Inclusive Pricing: Are tolls, bridge fees, fuel, luggage, and waiting allowances baked into fixed upfront rates, with clear rules for the night window (23:00–07:00) and overtime (HK$400 per hour)?
- 4. Quantifiable Service Level Agreements (SLAs): Are confirmation times, live support response times, driver detail lead times, and complimentary waiting buffers contractually defined?
- 5. Partner Portal & REST API Scalability: Can travel bookers and finance teams use a role-based portal with per-currency CSV exports, or connect directly via REST API and signed webhooks?

| Driver Dispatch & Support SLA | Ad-hoc messaging with no audit trail | Driver name, mobile, and plate sent via email & SMS 1 hour before pickup; after booking, the My order chat replies within five minutes, 24/7 |
| Booking Portal & Reconciliation | Manual spreadsheets and paper receipts | Contracted accounts receive a partner portal with multi-role permissions, monthly invoicing, and per-currency CSV statement exports |
| System Integration (API) | None; chat-based manual ordering | Standardised REST API (see API Integration) covering route discovery, quotes, idempotent booking creation, status lookup, and signed webhooks |
REST API & Signed Webhook Architecture Highlights
For TMCs, hospitality groups, and travel platforms embedding GBA ground transport into their own booking flows, Mayline provides a clean technical specification (see API Integration):
- Core Endpoints: Route availability, instant all-inclusive quotes, order creation and cancellation (with
externalOrderIdmapping and idempotency protection), and live driver assignment queries. - Event-Driven Webhooks: Automatic push notifications when an order is confirmed, assigned a driver, en route, completed, or cancelled—eliminating polling overhead.
- Enterprise Security: Requests and webhooks are authenticated with
HMAC-SHA256signatures andX-Timestampreplay protection, backed by a dedicated Sandbox environment.

Frequently asked questions
How do we qualify for monthly invoicing, the partner portal, and API access?
The multi-role partner portal, consolidated monthly invoicing, and REST API integration are available to corporate, hotel, and platform partners under a written agreement. Individual travellers and ad-hoc bookers can book instant all-inclusive rides online with automatic email receipts.
Can monthly billing statements be exported by currency for ERP ingestion?
Yes. The partner portal exports standardised monthly CSV reconciliation statements separated by billing currency, detailing order IDs, external reference numbers, travel dates, routes, and totals.
Is a sandbox environment available for API integration testing?
Yes. We provide a dedicated Sandbox environment alongside our REST JSON specification so your engineering team can test quote generation, booking creation, and webhook signature verification end to end.
