Elixir Microsoft Bot Framework Client

This library provides Elixir API wrapper for the Microsoft Bot Framework and handles authentication and token management.

Documentation

API documentation is available at https://hexdocs.pm/ex_microsofbot.

Installation

1. Add ex_microsoftbot to your list of dependencies in mix.exs:

def deps do
  [{:ex_microsoftbot, "~> 3.0.0"}]
end

2. Add the registered bot app id and app password in your config:

config :ex_microsoftbot,
  app_id: "BOT_APP_ID",
  app_password: "BOT_APP_PASSWORD"

3. Start the ex_microsoftbot:

def application do
  [applications: [:ex_microsoftbot]]
end

Usage

The main functionality is provided by three main modules that match each of the corresponding API endpoints of the Microsoft Bot Framework:

• ExMicrosoftBot.Client.Attachments,
• ExMicrosoftBot.Client.Conversations
• ExMicrosoftBot.Client.Teams

Example usage:

alias ExMicrosoftBot.Client.Conversations

def reply(activity = %Activity{}) do
  text = "Hello, world!"

  resp_activity =
    %Activity{
      type: "message",
      conversation: activity.conversation,
      recipient: activity.from,
      from: activity.recipient,
      replyToId: activity.id,
      text: text
    }

  Conversations.reply_to_activity(
    activity.serviceUrl,
    activity.conversation.id,
    activity.id,
    resp_activity
  )
end

Config

In addition to the required auth configs mentioned in Installation, there are a few more options available to customize this lib:

config :ex_microsoftbot,
  using_bot_emulator: false,
  scope: "https://api.botframework.com/.default",
  http_client_opts: nil

using_bot_emulator

Default false. Set this to true to disable the auth token manager, and instead use a fake auth token in all requests.

scope

Default "https://api.botframework.com/.default". This sets the scope used when authorizing with the BotFramework.

http_client_opts

This is passed on each request to the underlying HTTP client, HTTPoison. See the :options key in their docs here for all available options.

Connection Pools

This is currently undocumented in the link above, but HTTPoison allows specifying a connection pool and other :hackney options via the :hackney atom in the HTTP options. For example, to configure this library to use the :bot_framework dedicated pool:

config :ex_microsoft_bot,
  http_client_opts: [
    hackney: [pool: :bot_framework]
  ]
