This example project helps you validate Python SDK webhook signature verification locally.

• receiver.py: local webhook endpoint that verifies and parses events
• send_test_webhook.py: sends a signed test webhook request to your local endpoint

cd packages/python-sdk/example/webhook-test-project
python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

Terminal 1:

python receiver.py

Terminal 2:

python send_test_webhook.py

You should see:

• 200 response from the receiver
• parsed webhook event output in the receiver terminal

• BYTESEND_WEBHOOK_SECRET (default: whsec_test)
• WEBHOOK_URL (default: http://127.0.0.1:8000/webhook)

Use the same BYTESEND_WEBHOOK_SECRET for both scripts.
