Steps
Connect your PMS to Revinate using one of its 75-plus supported PMS integrations to enable automatic guest profile and reservation sync into the Revinate CDP
Access the Revinate API using the documented authentication method, which uses HMAC SHA-256 signing via the X-Revinate-Porter-Encoded header
Configure pre-arrival message sequences specifying trigger timing (such as a set number of days before check-in), message content, and the communication channel such as email or SMS
Use the Ivy AI messaging product for real-time SMS conversations, which handles routine guest inquiries, upsell offers for upgrades or late checkout, and service requests automatically
Retrieve and process guest replies or escalated conversations through the API or dashboard so that front-desk staff can respond to cases Ivy cannot resolve
Query guest history and preference data from the unified CDP profile to personalize message content and offers before dispatch
Known gotchas
Revinate syncs guest data from the PMS; inaccurate or incomplete guest profile data in the PMS (missing email addresses or phone numbers) causes messages to fail delivery silently without surfacing as API errors
HMAC SHA-256 signing requires the request body to be signed with a shared secret; any middleware that modifies the request body after signing but before transmission will cause signature validation failures
SMS opt-out regulations vary by country; sending automated messages to guests who have not explicitly opted in for SMS communications can violate local data protection or telecom regulations
