@farhansheikh I will be happy to provide more information in detail if you could share your use case. But, from what you stated: 

• For automating scheduling process - You could you use our List User Event Type to get Scheduling URL that you can share with external users from your own product. Once the meeting is booked, use this information to automate tasks on your end or just add record with meeting details such as invitee name/email, meeting details, etc. 
• For managing availability - we have APIs were you can view busy/available times for all of your users (provided you have admin access). We have added information regarding this in documentation section
   

Thank you for the detailed response! I appreciate the guidance.

My use case involves integrating Calendly with a custom CRM application. I’m looking to automate the scheduling process for our sales team by pulling available times and generating booking links directly within the CRM. We also want to automatically log meeting details in the CRM once a booking is confirmed.

I’ll review the documentation on viewing busy/available times and using the List User Event Type API. If there are any specific examples or best practices for integrating with a CRM, I'd love to hear about them.

Thanks again for your help!

To integrate Calendly with custom applications using the API effectively, follow these best practices:

1. **Use OAuth2 for Secure Authentication**: Ensure secure access, especially for multi-user accounts.
2. **Automate Scheduling**: Trigger event creation and sync availability dynamically with your app.
3. **Leverage Webhooks**: Get real-time updates on bookings, cancellations, and reschedules.
4. **Manage Availability**: Dynamically update availability, incorporate buffer times, and implement custom scheduling rules.
5. **Optimize User Experience**: Customize booking pages and generate personalized booking links.
6. **Implement Robust Error Handling**: Use error logging, retry logic, and regularly test the integration.
7. **Ensure Data Privacy**: Handle scheduling data securely and comply with regulations like GDPR.

These practices will help you automate scheduling and manage availability efficiently with Calendly.
