Is it possible to integrate a booking app on a website that connects with a Google Calendar to show available time slots and allows the client to approve appointments before adding them to the calendar? What are the preferred web apps or tools to achieve this with Webflow?

Yes, it is definitely possible to integrate a booking app on a website that connects with a Google Calendar to show available time slots and allows clients to approve appointments before adding them to the calendar. In order to achieve this with Webflow, you have a few options:

1. Zapier: Zapier is a web automation tool that allows you to connect different apps and services together. With Zapier, you can create a Zap (automation workflow) that connects your booking app with Google Calendar. When a client submits a booking request through the app, the Zap can create an event in your Google Calendar and send a notification to the client for approval. Once approved, the event can be added to the calendar. Some popular booking apps that integrate with Zapier include Calendly, Acuity Scheduling, and Setmore.

2. Custom Integration: If you have development skills or access to a developer, you can create a custom integration using the Google Calendar API. The API allows you to manage events, availability, and permissions programmatically. You can build a booking form on your Webflow website that sends data to your backend, where you can handle the integration with Google Calendar and the approval process. This option gives you more flexibility and control over the integration, but it requires technical expertise.

3. Third-party booking platforms: There are also third-party booking platforms that offer seamless integrations with Webflow and Google Calendar. These platforms provide pre-built booking widgets or embeddable forms that you can easily add to your Webflow website. Some popular options include Square Appointments, Timely, and SimplyBook.me. These platforms often handle the synchronization with Google Calendar and have built-in approval workflows.

When choosing a web app or tool to achieve this integration, consider factors such as your specific requirements (e.g., appointment types, custom fields), ease of setup and use, pricing, and compatibility with Webflow. Additionally, it's important to test and ensure that the chosen solution provides a seamless user experience for both clients and yourself, so you can efficiently manage appointments and availability.
