Backup your Wunderlist data into a JSON file.
This script produces similar output to the backup files generated by the Wunderlist web application export feature.
Ruby >= 2.0 (no extra gems needed)
You have to create an application in Wunderlist to get access to the required OAUTH data for authentication.
After that you see the "Client ID" and "Client Secret". Now you have to generate an access token.
Store that token in a secure location, it's only shown once!
Now you have to set two environment variables to allow the backup script to access the Wunderlist API. After doing that, just run the script.
$ export WUNDERLIST_ACCESS_TOKEN=<your Wunderlist access token> $ export WUNDERLIST_CLIENT_ID=<your Wunderlist client id> $ ruby wunderlist-backup.rb > wunderlist-backup.json
