Hi Zac Pagan,
Yes, it is possible to use Vapi to build voice agents for bars and restaurants even if the existing booking software does not offer API access. Vapi's Workflows allow you to design voice agents that handle complex customer interactions, such as scheduling and managing reservations, by using visual decision trees and conditional logic.
You can build a solution where the voice agent interacts directly with customers to take and confirm bookings, bypassing the need for direct API integration. Alternatively, you might consider manually syncing the data between the voice agent and the booking software.
For more detailed guidance on setting up such systems, you can refer to the [Appointment Scheduling example](
https://docs.vapi.ai/examples) which provides insights into building similar assistants.
