Review sources

Booking.com, Expedia, Tripadvisor and other platforms

Revinsta stores your exact listing URL for each platform (found automatically when you add a property) and is built to ingest reviews from all of them. Here is the honest status of each:

The integrations matrix shows what each platform supports

Google: live today, including full history and reply posting once Business Profile is authorized.
Booking.com / Expedia: their review APIs require a signed partner agreement with each company. These integrations are in progress; reply posting will be supported once approved.
Tripadvisor: read only content API planned; replies remain manual on their site.
Facebook: recommendations import planned via a Page connection.
Airbnb, Agoda, HolidayCheck, OpenTable: no open APIs; ingest options are being evaluated.

For any platform, the Copy & open button in the inbox copies your finished reply and opens your listing so posting manually takes seconds.
