Build your Retell AI and Google Calendar integrations.
When a conversation or call event occurs in Google Calendar, it triggers an automated workflow in Make that creates calendar events in Retell AI. Google Calendar serves as the trigger by detecting completed calls, customer conversations, or specific call outcomes, which then automatically initiates actions in Retell AI such as creating appointments, scheduling follow-up meetings, or adding events with relevant details from the AI-driven conversation. This integration eliminates manual data entry by automatically populating your Retell AI with events, reminders, and tasks based on voice AI interactions captured by Google Calendar.

Make offers a scalable pricing model starting with a free tier, allowing you to test integrations before committing. You can automate hundreds or thousands of tasks monthly for a fraction of custom development costs, with the added benefit of instant updates, reliability, and the ability to modify workflows as your needs evolve.
A scenario represents a workflow or a project of your own creation, and it is made up of a series of modules that automate apps and services. Creating a scenario allows you to transfer and transform data between apps and services via these modules to automate anything and improve the way you work.
Modules are the main building blocks of automation in Make. Modules represent actions that Make performs with an app, like creating, updating, or deleting data.
