Default Push data to Metawatch

Hi all,

new to the forum but search was unsuccessful so here goes. Is there a noobs guide to push data from an api (like fitbit) to the metawatch? or even pushing from any old webserver as (if i had to) I could pull the data via the api myself and then host it in a metawatch friendly way. however my issue is that I have no idea how the metawatch would read that data.

any pointers/guides out there?
