REST API Log

Exactly what I needed

its trash.
whilst i do like the idea of the plugin, this tool is simply not working properly. guess it's abandoned. 
there is a filter build in to filter for the request type, but it does not work (simply doesn't filter at all). and there is an option, to purge logs, that are older than x days, but this doesn't work ether. and deleting the logs takes ages, you might want to do that in the db directly. so handle with care, as it will bloat the db and it'll be hard to find the data, you might be looking for..

don't!!1!

This is great tool to log REST API calls. Period.

1 star? 5 stars!
