Delivery Confirmation & Signature
Confirm high-value deliveries with recipients, collect verbal acknowledgment, and create a timestamped audit record — without requiring a physical signature.
Why this matters
Keep freight moving with automated delivery confirmation, carrier check-ins, claims intake, and compliance data collection. This example shows you how to automate delivery confirmation & signature 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.
