Order Status & Delivery Updates
Proactively notify customers about order status changes, delivery windows, and exceptions — reducing WISMO calls to your support team.
Why this matters
Drive revenue and retention with voice automation for order updates, cart recovery, loyalty enrollment, and post-purchase engagement. This example shows you how to automate order status & delivery updates calls end-to-end with Guava's SDK — no telephony plumbing, no prompt engineering, just Python.
Installation
Install from Guava's private PyPI index. A public package is coming soon — the install command will simplify to pip install guava.
# 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

Every Guava agent is a Python class. Walk through the key sections below, then grab the complete file at the end.
Imports
Import the Guava SDK and any helpers you need. guava.CallController is the base class for every voice agent.

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.

)Run it
Start the agent. It will connect to Guava's infrastructure and begin accepting calls on your assigned number.
