Schedule Once is a leading scheduling automation platform that streamlines the process of booking meetings and appointments.
Transform your scheduling workflows with AI agents that can intelligently coordinate calendars, manage availability, and automate booking processes.



Schedule Once streamlines meeting coordination across teams and time zones. Relevance AI enhances this with intelligent AI agents that can autonomously manage complex scheduling scenarios and optimize calendar management.
Intelligent Scheduling Orchestration
The agent autonomously coordinates complex meeting schedules, optimizing for all participants' availability.
Proactive Conflict Resolution
The agent identifies and resolves scheduling conflicts before they arise, ensuring seamless meeting arrangements.
Automated Follow-Up Engagement
The agent sends timely reminders and follow-ups, enhancing communication and reducing no-shows.
Relevance AI gives you access to Schedule Once's scheduling capabilities within your automated workflows and AI agents.
What you’ll need
You don't need to be a developer to set up this integration. Follow this simple guide to get started:
- A Schedule Once account
- A Relevance AI account with access to your workspace
- Authorization (you'll connect securely using OAuth—no sensitive info stored manually)
Security & Reliability
The integration uses secure OAuth authentication, ensuring only authorized workflows access your ScheduleOnce scheduling data. Relevance AI handles API operations (like GET, POST, PUT, DELETE) in the background—so you don't have to worry about authentication tokens, request formatting, or rate limits.
Built-in validation and error handling ensure your scheduling workflows run reliably, even with complex booking scenarios.
No training on your data
Your data remains private and is never utilized for model training purposes.
Security first
We never store anything we don’t need to. The inputs or outputs of your tools are never stored.

Best Practices for Non-Technical Users
To get the most out of the ScheduleOnce + Relevance AI integration without writing code:
- Configure booking settings: Set up clear scheduling rules and availability windows first.
- Use OAuth properly: Ensure proper authentication by connecting with the correct ScheduleOnce account permissions.
- Structure API calls: Follow RESTful patterns when making requests to the ScheduleOnce API endpoints.
- Handle responses: Implement proper error handling for scheduling conflicts and API limits.
- Monitor webhooks: Set up reliable webhook endpoints to receive real-time booking notifications.
