Crypto Price Bot for Slack, which posts price and market cap updates from CoinMarketCap at regular intervals. Originally built for the Golem Slack.

Requirements

• A web server with PHP 5 and cURL installed

Installation and Configuration

Slack Configuration

1. In Slack, create a new incoming webhook integration and choose the chanel, label, name and icon that you want the bot to use.
2. Optionally, create a second incoming webhook integration to be used for testing any code changes you want to make to the bot (you will probably want this second webhook to post to a private group rather than a public channel).
3. Add the 3 png files as custom emoji. Alternatively, you can use your own emoji and edit the required variables in variables.php.

Web Server Configuration

1. Download the files (or do a git pull) to a directory on your webserver
2. Edit variables.php with the settings you require. At a minimum you will need to set the following:

• $url_slack - the webhook URL created above
• $url_slack_dev - the optional second webhook URL created above
• $script_name- the location of index.php on your webserver
• $script_name_dev- the location of dev.php on your webserver
• $token_symbol - the 3 or 4 letter token symbol
• $token_api_name - the id (not name) of the token used by the CoinMarketCap API

3. Create a cron job or scheduled task to run index.php at the required interval.

Running Multiple Bots

If you wish to have regular updates on multiple different tokens/coins, you will need to create multiple directories on your webserver (one for each token/coin) and have a copy of the php files in each. You will also need to create a cron job or scheduled task for the index.php in each directory. As long as they are posting to the same slack channel, you will not need to create additional webhooks.

Troubleshooting

• running index.php?mode=live in a web browser will output the result to the browser, rather than posting it to the Slack channel
• dev.php is an exact copy of index.php. It exists so that you can edit and test the code without it affecting the scheduled posts when index.php is run by cron or scheduled tasks.
