Requirements:

SignalWire Coding Challenge

This challenge is designed to be representational of the type of functionality we often do at SignalWire. The challenge should ideally not take longer than 1 hour to implement.

The challenge is to build an API route, that accepts a JSON payload that looks like:

{
  "user_id" : 1234,
  "title" : "My title",
  "tags" : ["tag1", "tag2"]
}

• The route should validate that user_id and title are present, tags can be empty, but must also be fewer than 5.
• If valid, the request should:
  • Store the user_id and title in a table named tickets, along with the datetime it was received.
  • Keep a running count of all the case-insensitive tags received in a table named tags.
  • Send a webhook request to a URL containing the tag with current highest count. No specific requirements, just be sure to include the tag in the request query string or body. Feel free to use a website like https://webhook.site/ to send the request to.
• If invalid, the request should:
  • respond with a 422 and a JSON payload explaining the validation errors.

You SHOULD:

• Provide a working, runnable Rails application that accepts requests on port 3000.
• Provide specs that test the above behaviour.
• Use any gems or libraries you want.
• Deliver via a git repository, zip file, gist.

You SHOULD NOT:

• Worry about UI
• Worry about authentication or authorization
• Configuring the Rails application, security, environments, etc.

Feel free to reach out if you have any questions!

Assumptions:

• Always create new ticket for each POST request, even with the same title. There is no uniqueness validation in the requirements.
• One ticket has many tags.
• One tag can be attached to many tickets.
• If there are many tags with the same max count, send all of them to webhook.
