pretix Waiting List SMS

This is a pretix plugin that sends an SMS notification when a waiting list entry receives a voucher.

AI-generated project

This project's code and documentation were generated by AI coding assistants (Claude, Codex, and Gemini). It has not been independently audited; review it carefully before relying on it in production, particularly the parts that handle SMS gateway credentials and personal data.

Supported SMS gateways:

• Pingram
• Twilio
• Generic HTTP JSON webhook

Installation

Install the plugin in the same Python environment as pretix:

pip install pretix-waitinglistsms
python -m pretix rebuild

Then restart the pretix web and worker processes.

Configuration

Enable the plugin for an event, then open the event settings page and configure Waiting list SMS. The plugin sends messages only if all of these conditions are true:

• the plugin is active for the event
• SMS notifications are enabled in the plugin settings
• a waiting list entry has a phone number
• a voucher has been assigned to the waiting list entry
• no successful SMS log entry exists for the waiting list entry yet

Message placeholders

The message template supports these placeholders:

• {event}
• {item}
• {variation}
• {voucher_code}
• {voucher_valid_until}
• {url}

Data privacy

The plugin does not store any personal data itself. However, to deliver a message it transmits the waiting list entry's phone number (and the message content, which may include the event name and voucher code) to the SMS gateway you configure (Pingram, Twilio, or your own HTTP endpoint). Make sure your privacy statement covers this processing and that you have a data processing agreement with the gateway provider where required.

Development

Install in editable mode for local development:

pip install -e .
