Pre-Filled Online Check-In Links for OTAs and External Vendors

Paulina
Updated

Overview

Duve enables external vendors, OTAs, and travel agents to generate direct links to Duve’s Online Check-In (OCI) portal with pre-filled guest information using URL query parameters. 

When guests click these personalized links, their booking details are automatically populated in the login form, allowing them to proceed to Online Check-In quickly and without manual data entry.

Benefits Include:

  • Reduced friction in the guest journey
  • Increased Online Check-In conversion rates for hosts with missing guest details
  • Lower support burden for property staff
  • Improved guest satisfaction
  • Competitive advantage for properties using Duve

This functionality is available to all Duve customers.

How it Works

  1. Partner Generates the Link

Partner embeds a pre-filled Check-In Portal URL in the guest voucher with booking data.

  1. Guest Clicks Link

Form fields are auto-populated from URL parameters. No manual data entry needed. 

  1. Instant Check-In

Guest clicks Login and proceeds directly to Online Check-In flow.
 

How to Set Up

First navigate to Settings > General > Guest Login 

Hotels must enable the appropriate login method (Email, Phone, Booking Number, or Full Name + Dates).

If a login method is disabled, the corresponding Sign-in Option (sio) value will not work.


 

Next navigate to Settings > Check-In > Check-In Portal and enable the Check-In Portal toggle.


 

Copy the Base URL

Each hotel has a unique portal URL in the format:

https://m.duve.co/cip/{portalId}



Append Parameters

Add query parameters with guest data to pre-fill the login form.

Important Notes

  • The Check-In Portal link must be configured at the brand level, not at the account level.

  • Each brand should have its own unique Check-In Portal link.

Attribution (affType)

Use the affType parameter to track which partner generated the check-in.

  • This value is captured as the UTM source after a successful login.

Default Recommendation

  • Use sio=3 (Booking Number) when the partner has access to the reservation ID.

  • If the reservation ID is not available, use sio=7 as a fallback.

1 - Email

  • Email-based login
  • Pre-fills email, check-in date
  • Fields: email, checkInDate

2 - Phone

  • Phone-based login
  • Pre-fills phone number, check in date
  • Fields: phoneNumber, checkInDate

3 - Booking Number

  • Reservation ID login
