GCP Cloud Functions Setup

This application uses Google Cloud functions as a backend. We mainly use 4 HTTP Triggers Endpoint:

  • authorizeLyrebirdUser: OAuth Endpoint for Lyrebird Authorization.
  • getSlackToken: OAuth Endpoint for Slack Authorization.
  • voicifySlack: Endpoint that receives the Slack Voicify request.
  • voicifyHandle: Endpoint that calls Lyrebird Vocal Avatar in order to voicify the request.

This tutorial is a great place to help you get started. It demonstrates using Cloud Functions to implement a Slack Slash Command.
