iGMS Integration

iGMS stays your channel manager and team tool. Haven is the branded direct-booking site, checkout, guest portal, ID check and rental agreement on top.

Connect from Settings → Integrations (/host?tab=integrations) → Connect iGMS, sign in to iGMS and click Allow. Each iGMS property becomes one Haven listing. Listing content, nightly prices, minimum stays and availability sync from iGMS, your existing iGMS reservations import when you connect and new or changed ones reach Haven as they happen, and Haven bookings are created in iGMS. No iCal feed is required.

When to use it

Use the iGMS connection when iGMS runs your calendars and channels and you want a direct booking site that keeps them closed together. If you would rather connect through Airbnb, that still works, but a booking taken on Haven then reaches iGMS only through the Haven iCal feed.

How to connect

  1. Sign in to Haven and open Integrations.
  2. Click Connect iGMS. You can also choose iGMS on onboarding's Connect your PMS step.
  3. Sign in to iGMS and click Allow on iGMS's permission screen. Haven asks iGMS only for the access iGMS has enabled for Haven: today your listings, direct bookings and calendar control.
  4. Back in Haven, choose which iGMS properties to bring in. If you already have Haven listings, match each iGMS property to its Haven listing instead of importing a duplicate.

Haven never sees or stores your iGMS password. Already connected through Airbnb? Connect iGMS as well and match each property to the listing you already have, so nothing is duplicated. See Switch or Add a PMS Without Duplicating Your Properties.

What syncs from iGMS

  • Listing content: Haven reads the property's direct booking listing in iGMS (the one iGMS uses for its own booking website): description, photos, amenities, guest capacity, beds, check-in and check-out times, house rules, whether children, infants and pets are welcome, and the cancellation policy as text. The name, address, map pin, bedrooms and bathrooms come from the iGMS property itself.
  • Fees and taxes from that direct booking listing: the cleaning fee, the extra-guest price, the pet fee, other fees, and taxes. A fee Haven cannot price exactly is flagged, not charged.
  • Calendar: the nightly price, minimum stay and availability for every night.
  • Reservations from Airbnb, Vrbo, Booking.com and iGMS's own site, with the dates, status, number of guests and price. The guest's name and contact details arrive separately, when iGMS sends them for an upcoming stay (see below). Owner stays arrive as blocked dates.

A property with no direct booking listing in iGMS still imports, with its name, address, rooms and check-in times. Set its description, photos and fees in Haven, or turn on iGMS's direct booking website for it and click Sync now. The card at the top of the listing editor's sidebar lists what is missing under Worth checking.

Reservations made before you connected

Your existing iGMS reservations import when you connect: every stay that has not ended yet, plus the last 30 days, appears on the Haven calendar and in your reservations as a real reservation, with its dates, channel, number of guests and price. Cancelled ones free their nights.

Unless your connection includes Guest details on every stay (see Guest messages, reviews, door codes and Airbnb requests), iGMS sends a guest's name and contact details on their own, only for upcoming stays, and not always at the moment the reservation arrives. Until it does, the reservation shows without a guest name, with its channel, dates and number of guests; the name and contact fill in on their own once iGMS sends them. A stay that has already ended stays without a name.

What Haven sends to iGMS

  • Haven bookings are created in iGMS as direct bookings with Haven's total, so the dates close on every channel iGMS manages. Haven already collected the payment, so iGMS does not invoice the guest. iGMS itself does not stop a booking on nights that are already taken, so Haven checks the iGMS calendar first: if any of the nights is closed in iGMS by then, Haven does not create the booking there and tells you, so you can resolve the overlap in iGMS. Date changes are checked the same way.
  • Date changes, guest-count changes and cancellations on bookings made on Haven. Cancelling a Haven booking cancels it in iGMS.
  • Blocks you set in Haven, and nights you open again.
  • Prices and minimum stays you set on selected dates in Haven. A listing set to Manage pricing in Haven keeps its Haven rates on Haven only: none of them are sent to iGMS, and iGMS keeps pricing its channels.

Closed-to-arrival and closed-to-departure rules have no place in iGMS, so they apply on Haven only. If you switch off calendar control for a property in iGMS, Haven cannot change that property's iGMS calendar until you switch it back on.

Guests who book on Haven

A booking Haven creates in iGMS carries a Haven relay address instead of the guest's own email, and no phone number. Anything iGMS emails that guest, such as an iGMS automated message or a reply you send from the iGMS inbox, comes to Haven first and reaches the guest from Haven under your branding. It also shows on the stay's thread in Haven's Messages, marked via iGMS. Every such email is passed on, because an email does not say whether an automation or a person sent it. To keep an iGMS automation from reaching guests who booked on Haven, switch it off for direct bookings in iGMS.

How often iGMS syncs

New and changed reservations reach Haven the moment iGMS sends them, and Haven also re-reads your iGMS reservations every 6 hours, so a change that did not arrive still lands. Prices, minimum stays and availability are read from iGMS every 6 hours too, and right away when you click Sync now on the iGMS card. Haven bookings are sent to iGMS as soon as they are confirmed.

Guest messages, reviews, door codes and Airbnb requests

These need access that iGMS enables for Haven separately. The iGMS card's What syncs row shows each one as on or off for your connection. An item marked off is not available yet. Once iGMS has enabled it for Haven, the card shows Reconnect to turn on with the items it adds: click Reconnect iGMS, then Allow in iGMS.

  • Guest messages: your Airbnb, Vrbo, Booking.com and iGMS direct-booking conversations appear in Haven's Messages, including the earlier messages of every imported stay (marked read). A message a guest edits or unsends on Airbnb changes in Haven too. Haven also checks for missed messages every 6 hours.
  • Replies to guests: replies you type in Haven, AI replies to OTA guests, the guest portal auto-send and your custom automations go into the guest's Airbnb, Vrbo or Booking.com conversation through iGMS, or by email for an iGMS direct booking. AI replies and automations stay off until you turn them on, and earlier messages Haven brings in are never sent again. Haven never posts into a booking Haven created; it messages that guest itself.
  • Guest details on every stay: the guest's name, email and phone on every imported reservation, not only upcoming ones.
  • Guest reviews: reviews guests leave on your iGMS channels appear in the listing's reviews, and private feedback in Guest insights.
  • Door codes: the door code Haven gives a guest, from a smart lock or typed on the reservation, is written onto the iGMS booking. iGMS may message the guest the code itself if your iGMS automations do that. See Door Codes & Smart Locks.
  • Airbnb requests and changes: accept or decline an Airbnb request to book, or a guest's request to change their dates or guests, from the Airbnb requests list on the iGMS card or the On Airbnb section of the stay. Declining needs one of Airbnb's reasons and a message to the guest. Airbnb's answer reaches the booking shortly after.
  • Opening and closing nights: Haven opens and closes nights in iGMS with a method that confirms every night. If iGMS refuses a night, the sync names the dates and iGMS's reason. Without it, Haven opens and closes nights through the calendar update, which iGMS does not confirm night by night.

What does not sync

  • Haven details on iGMS bookings: Haven can't write the guest portal link, ID check or signed agreement onto an iGMS reservation.
  • Content you edit in Haven is not sent back to iGMS.
  • Wi-Fi details: set them in Haven.

Disconnecting

Disconnect on the iGMS card stops syncing. Your iGMS properties and reservations are not changed, and the listings you imported stay on Haven. iGMS has no way for Haven to withdraw its own access, so Haven stays listed among your connected apps in iGMS until you remove it there. If you revoke Haven's access in iGMS first, Haven disconnects too.
