Contact ShowingTime directly via sales@showingtime.com or 800-347-8001 to inquire about partner API access; ShowingTime does not publish a self-serve public developer API
If your platform is an MLS technology vendor, explore integration through ShowingTime's MLS data distribution and RESO Web API certified feed for listing data, which is separate from the showing scheduling functionality
For showing scheduling within MLS workflows, use ShowingTime's existing MLS-embedded integrations where they exist, or ask the MLS to enable API-level access for authorized technology partners
Implement a generic showing-request workflow using your own scheduling logic: validate listing availability against a calendar, send confirmation requests to listing agents via email or SMS webhooks, and store confirmed showing windows in your database
For platforms not integrated directly with ShowingTime, provide deep links into ShowingTime's agent-facing interface for manual scheduling rather than attempting unauthorized API calls
Monitor ShowingTime+ announcements for any expanded partner API program, as the platform is part of Zillow Group and capabilities may expand
Known gotchas
ShowingTime does not offer a publicly documented REST API for third-party showing scheduling as of 2026; any integration must go through a formal partnership channel
Attempting to scrape or automate ShowingTime's web interface violates its terms of service and will result in account termination
Generic calendar-based showing schedulers can substitute for direct ShowingTime integration in many workflows — evaluate whether ShowingTime-specific integration is truly required before pursuing a partnership
