Spara's AI can intelligently push leads to schedule a call with your sales team. To accomplish this, Spara supports integrations with most major third party calendar scheduling solutions. {% hint style="info" %} Spara strongly recommends Cal.com as a calendar provider. {% endhint %} Each agent type uses calendars differently: * **Chat agents** render a calendar widget directly in the conversation for the lead to pick a time * **Email agents** include links to your calendar booking page * **Phone capabilities** handle booking entirely by conversation — Spara reads available slots aloud, the lead picks a time, and it books the meeting. See [Phone](/build/channels/phone.md) for details on the voice booking flow. All Spara agents can route leads to specific calendars based on any information known about the lead. Spara supports both round robin calendars and routing to specific sales reps' calendars (through Salesforce integration only). See [Salesforce](/integrations/crm-integrations/salesforce.md#owner-objects) documentation for more details. Spara's integrations are sometimes limited by what each calendar's API makes available. In all cases, Spara is immediately alerted whenever a calendar event has been scheduled, meaning that Spara's behavior can react to this situation. After a call is scheduled, it is common to configure Spara to send a success message and then ask additional prequalification questions. Please see our calendar integration guides, including installation instructions and calendar limitations, in the table below:

## Voice agent calendar booking Voice agents book meetings by conversation — the agent reads available slots aloud, the lead picks a time, and the agent books it directly. This is a different integration path than the calendar widgets above, which embed a scheduler for the lead to fill in. The table below covers which calendar providers Spara supports for voice scheduling today.

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.spara.com/integrations/calendar-integrations.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
