Slack doesn't provide an easy way to extract custom emoji from a team. (Especially teams with thousands of custom emoji) This Gist walks you through a relatively simple approach to get your emoji out.
If you're an admin of your own team, you can get the list of emoji directly using this API: https://api.slack.com/methods/emoji.list. Once you have it, skip to Step 3
HOWEVER! This gist is intended for people who don't have admin access, nor access tokens for using that list.

Copies all keys from the source Redis host to the destination Redis host. | |
Useful to migrate Redis instances where commands like SLAVEOF and MIGRATE are | |
restricted (e.g. on Amazon ElastiCache). | |
The script scans through the keyspace of the given database number and uses | |
a pipeline of DUMP and RESTORE commands to migrate the keys. | |
Requires Redis 2.8.0 or higher. |

Copy this into the console of any web page that is interactive and doesn't | |
do hard reloads. You will hear your DOM changes as different pitches of | |
audio. | |
I have found this interesting for debugging, but also fun to hear web pages | |
render like UIs do in movies. | |
