This document outlines setting up google's ruby gem, google-api-client, to verify payloads(receipts) sent to a server from google play in app purchases made via an android app.
This document was written using version 0.9.13.

First you'll need 'owner' access to the google play developer's console that contains the mobile app you wish to verify receipts from.

• Go to https://play.google.com/apps/publish
• Click on the mobile app you'd like to set up
• Click "Settings" on the left click "API access"
• Below "LINKED PROJECT" link the google play account

Next setup an api account

• Kinesis Freestyle (Terrible key switches. Mushy and un-lovable)

• Kinesis Freestyle Edge (Traditional layout with too many keys, mech switches, proably too big to be tented easily/properly)

• Matias Ergo Pro (Looks pretty great. Have not tried.)

• ErgoDox Kit (Currently, my everyday keyboard. Can buy pre-assembled on eBay.)

• ErgoDox EZ (Prolly the best option for most people.)
