I've recently developed software on Microsoft's Cloud platform Azure and Slack Bot APIs in order to come up with a nice spread of real-time Bitcoin Transaction Fees. I wanted to share with you how I've done this and perhaps you can use it yourself as well.
All source code is published on my GitHub Gist.
Architecture Overview
Step 1
User issues a configured Slash command such as /fees which sends an HTTPS Request to the Azure Function.
Step 2
- The Azure functions pulls real-time Bitcoin Transaction data from http://bitcoinfees.earn.com.
- Computes transactions fees in very slow, slow, medium, and fast categories.
- Does some nifty code to parse out the Slack user who invoked the slack bot
- Sends an HTTP webhook back to the Slack Bot
Step 3
The Slack bot sends the results back to the Slack channel
So if I go into Coinbase right now and try to send BTC to another address, it'll charge me ~$16 USD which as you can see is on the faster side (roughly 36min) of the transaction fees. If you could manually adjust the speeds, you can easily pay about $1 and just get it the next day.
Here is a screenshot of configuring the actual Slack Bot application
The Azure Function itself is written in Microsoft PowerShell code which can be downloaded here:
Enjoy!
