The Late Check-in Notifications module pulls today’s expected arrivals from your PMS or from a manually uploaded XLSX file, filters the list against your company’s configured cutoff time, and surfaces only the guests who need to be proactively contacted. Instead of scanning a full arrivals list every morning and mentally filtering for late arrivals, your reception team sees only the actionable guests — together with a ready-to-send message built from your pre-approved templates in the Communications Vault.Documentation Index

How it works
Check the status dashboard
Call the status endpoint to see the current PMS connection state, today’s full check-in list (or an indication that no PMS is connected), and the cutoff hour your company has configured.You can optionally pass a Response (200):When
fecha query parameter (YYYY-MM-DD) to inspect a date other than today:pms_conectado is false, the checkins_hoy array will be empty — use the XLSX upload flow described in the next step instead.Upload an XLSX file (fallback)
If no PMS integration is configured, upload a spreadsheet exported from your PMS. The API parses it, applies the cutoff time filter, and returns only the late check-ins. Nothing is stored.Response (200):Only rows where the arrival time is later than the company’s
hora_corte are included in the response. Rows with missing or unparseable times are reported as warnings.This endpoint is rate-limited to 20 requests per hour.Guest data from the XLSX file is processed entirely in memory and is never written to the database. This is consistent with Stay Sidekick’s GDPR-first approach — the platform is a satellite tool, not a data warehouse.
Compose and send the notification
Pick a template from your company’s vault (category
CHECKIN_TARDIO) and use it as the base for the notification message. Templates can include dynamic placeholders such as {NOMBRE}, {APARTAMENTO}, {HORA_LLEGADA}, and {PROTOCOLO_CHECKIN}.See Managing notification templates below for how to create and manage templates for this module.Managing notification templates
Templates for late check-in notifications live in the Communications Vault under theCHECKIN_TARDIO category. You can manage them directly through the notifications module endpoints — any template created here also appears in the full Vault.
List templates:
nombre and contenido are required. The template is automatically assigned the CHECKIN_TARDIO category and the es language.
Update an existing template:
Cutoff time configuration
The cutoff hour defines when an arrival is considered “late.” It is stored per company and applies to both the PMS-based status check and the XLSX upload parser. Read the current cutoff configuration:HH:MM 24-hour format. Any arrival with a scheduled check-in time strictly after this hour is flagged as a late check-in.
Only company administrators can modify the cutoff time. Regular users can read the configuration and see the late check-ins list, but cannot change the threshold.
