README

This bundle provides the basic functionality to quickly connect your Slack Bot with your symfony project via slash commands.

Simply create a class, implement the provided CommandInterface and tag it as "slack.command" and your slash command is ready to go!

SlackBundle validates the token sent with the request to ensure this request comes authorized and from Slack. Then it searches for an service tagged with slack.command which tells to supported a given request. After collecting data from all suppported services it will respond to slack.

Dependencies

• Symfony 3.1
• PHP 7.0

Setup

• Create your own command class and implement Gotoemma\SlackBundle\Service\CommandInterface
• Tag your service with "slack.command"
• Go to https://api.slack.com/apps and create an app
• Add the clientId, clientSecret and token to your the config.yml
• Setup your first slash command and set https://your.url/webhook/slack as webhook url (use POST request)

"repositories": [
        {
            "type": "git",
            "url": "https://bitbucket.org/gotoemma/slack-bundle.git"
        }
    ],

Then type composer require gotoemma/slack-bundle

app/config/config.yml

slack:
  client_id:      "%slack_client_id%"
  client_secret:  "%slack_client_secret%"
  token:          "%slack_token%"

Your first command provider

With SlackBundle ships one default command: /list This command lists all registered commands in slack. The only thing you need to do is to add the slash command on api.slack.com/apps.

This command can be used as a basis for your first custom command also.
