Ticketmaster Bot

Ticketmaster Bot is a Discord bot designed to alert users every time a new event becomes available on Ticketmaster. Built for a ticket resale company based in NYC, it ensures users receive timely updates about upcoming events and provides powerful tools for managing event notifications.

Features

• Event Alerts: Automatically notifies a Discord server when new events are added to Ticketmaster.

• User Commands:

  • !next: Displays events with tickets going on sale next.
    
  • !addartist <artistID>: Marks an artist as notable, sending their events to a dedicated high-profile channel.
    

• API Crawlers: Continuously fetch new events from Ticketmaster’s API for four regions in North America.

Tech Stack

• Programming Language: Python
• Database: PostgreSQL
• Hosting: Heroku
• APIs:
  • Ticketmaster Discovery API
  • Discord API
• Deployment: CI/CD pipeline auto-deploys updates to Heroku from GitHub.

Architecture

The project is composed of two key components:

1. API Crawlers: Four Python scripts, each assigned to a specific North American region, poll the Ticketmaster API every minute and store new events in a PostgreSQL database.
2. Bot Script: The Discord bot retrieves unsent events from the database, posts them in designated channels, and handles user commands.
   Example request:
   https://app.ticketmaster.com/discovery/v2/events?apikey=YOUR_API_KEY&source=ticketmaster&locale=*&size=199&page=1&onsaleStartDateTime=2024-12-27T00:00:00Z&classificationId=CONCERTS&onsaleOnAfterStartDate=DATE&sort=onSaleStartDate,asc&latlong=CENTER&radius=DIST&unit=miles

Challenges & Solutions

• Rate Limits: The Ticketmaster API enforces a rate limit of 1000 events returned per query.
  

  • Solution: Run five separate Heroku servers (four crawlers and one bot) to distribute requests and avoid exceeding rate limits.
    

• Storage Efficiency: Optimized database structure to handle high-frequency updates and large datasets effectively.
  

Future Development

• Expand coverage to include events from other continents.
• Optimize database queries for better performance.
• Add new Discord commands and enhance logging mechanisms.
• Improve bot scalability and error handling.

Installation

1. Clone the repository:

   git clone https://github.com/adenjonah/TicketMasterBot.git

2. Install dependencies:

   pip install -r requirements.txt

3. Set up your environment variables:

   • TICKETMASTER_API_KEY
   • DISCORD_CHANNEL_ID
   • DISCORD_CHANNEL_ID_TWO
   • DISCORD_BOT_TOKEN
   • DATABASE_URL
   • DEBUG_LOGS (1 if on, 0 if off)
   • CENTER_POINT (long, lat of the zone you want to crawl)
   • RADIUS (in miles)
   • UNIT=miles
   • REDIRECT_URI=http://localhost
     Example .env

      TICKETMASTER_API_KEY='P7v8iurhq2a9r84o84irqo2uhq'
      DISCORD_BOT_TOKEN='MKSEalfnj87yBbE8.GHQ_Cx.KHGbkFHBFYUBFI-ri_XY'
      DISCORD_CHANNEL_ID='3795263749501923847509'
      DISCORD_CHANNEL_ID_TWO='73425974283745975392785'
      REDIRECT_URI='http://localhost'
      DATABASE_URL='postgres://7stfuastdg88:utaf8sfiasgig9asiygfouasgf0.cluster-s78syag9.us-east-2.rds.amazonaws.com:26739/aiysgfyasg98f'
      DEBUG_LOGS='1'
      CENTER_POINT=43.89789,-72.84782
      RADIUS=685
      UNIT=miles
     

4. Deploy to Heroku or run locally using the provided scripts (run newbot.py and crawler.py at the same time).

Usage

• Add the bot to your Discord server.
• Configure the database with your Ticketmaster API regions and preferences via environment variables.
• Start receiving real-time alerts and use commands like !next and !addartist to interact with the bot.
