Connection priority
Start with the Withinstay dashboard as the system of record, then add delivery and backup connections around it.
Withinstay dashboard data
Native tenant database with role-controlled dashboard access
Withinstay is the canonical database. External services deliver guests into the flow, send messages or receive optional backups; they do not become the operating database.
System of record
Hosted pre-arrival forms
Withinstay hosted branded links
This becomes the universal layer: every host gets a branded arrival form link that can be sent through any platform message, email, WhatsApp or PMS template.
Native core
Resend
Server-side API key with verified sending domain
Resend becomes the hosted transactional email layer for Withinstay, with optional hosted template IDs and webhooks for sent, delivered, bounced, complained and suppressed events.
Email backbone
Google Sheets
Google OAuth 2.0 or service account for host-owned backup sheets
Sheets is an optional one-way backup/export for hosts who want their own copy. Withinstay remains the dashboard and system of record.
Optional backup
Airbnb message templates
Host-managed Airbnb scheduled quick replies
This avoids restricted Airbnb APIs: the host uses Airbnb’s own automated guest messaging to deliver a Withinstay form link.
Template delivery
Booking.com message templates
Host-managed Booking.com extranet/Pulse messaging
This avoids needing full Connectivity API access on day one while still reaching Booking.com guests through supported messaging surfaces.
Template delivery
Core data model
These are the objects Withinstay owns before any optional Google Sheets backup export is created.
