Appointment Reminders & Scheduling

Automatically remind patients of upcoming appointments and handle rescheduling in a single call, reducing no-shows and freeing front-desk staff.

Why this matters

HIPAA-compliant voice automation for patient engagement, scheduling, and clinical workflows. This example shows you how to automate appointment reminders & scheduling calls end-to-end with Guava's SDK — no telephony plumbing, no prompt engineering, just Python.

Step 01

Installation

Install from Guava's private PyPI index. A public package is coming soon — the install command will simplify to pip install guava.

terminal
# Step 1: Install Guava
pip install gridspace-guava --extra-index-url https://guava-pypi.gridspace.com

# Public PyPI package coming soon — the install command will simplify to:
# pip install guava

# Step 2: Set your credentials
export GUAVA_API_KEY="..."
export GUAVA_AGENT_NUMBER="..."
Step 02

How it's built

Every Guava agent is a Python class. Walk through the key sections below, then grab the complete file at the end.

01

Imports

Import the Guava SDK and any helpers you need. guava.CallController is the base class for every voice agent.

example.py
# Install: pip install gridspace-guava --extra-index-url https://guava-pypi.gridspace.com
import guava
import os
from datetime import datetime

Agent setup

set_persona() defines how the agent presents itself. set_task() gives it its mission in plain English. The checklist drives the conversation — Guava works through it top-to-bottom, collecting Field values and speaking Say items as it goes.

example.py
class AppointmentReminderBot(guava.CallController):
    def __init__(self, patient_name: str, provider: str, appt_time: str, clinic: str):
        super().__init__()
        self.patient_name = patient_name
        self.appt_time = appt_time
        self.set_persona(
            organization_name=clinic,
            agent_name="Maya",
        )
        self.set_task(
            objective=f"Remind {patient_name} of their appointment with {provider} on {appt_time} and confirm attendance or reschedule",
            checklist=[
                f"Greet {patient_name} and confirm you're speaking with the right person.",
                guava.Field(
                    key="confirmed_attendance",
                    field_type="bool",
                    description="Does the patient confirm they will attend?",
                ),
                guava.Say("if not attending, offer to reschedule"),
                guava.Field(
                    key="new_slot",
                    field_type="calendar_slot",
                    description="Preferred reschedule date and time",
                    required=False,
                    choice_generator=self.get_open_slots,
                ),
                "Thank the patient and confirm any changes.",
            ],
            on_complete=self.handle_result,
        )

    def get_open_slots(self):
        # integrate with your scheduling system
        return ["Monday 9am", "Monday 2pm", "Tuesday 10am", "Wednesday 3pm"]

    def handle_result(self, fields):
        if not fields.get("confirmed_attendance"):
            new_slot = fields.get("new_slot")
            print(f"Rescheduled {self.patient_name} to {new_slot}")
        else:
            print(f"{self.patient_name} confirmed for {self.appt_time}")

guava.dial(
    controller=AppointmentReminderBot,
    controller_args={"patient_name": "Sarah Chen", "provider": "Dr. Patel",
                     "appt_time": "Thursday at 2:00 PM", "clinic": "Westside Medical"},
