Many thanks @Andrii_Magalich for sharing this, really low effort way in to having a play with this excellent API.
In case of interest or helps anyone else, here’s a link to the doc I built based on what you shared:
Main thing the sheet is for is to suggest what your next activity could be to achieve a user specified Form value - in the sheet imaginatively called “Next Activity”. Also recreates the fitness/fatigue chart.
To make it work take a copy, then your details (user number and API key) simply need to be entered in the red cells near the top of the sheet called "Daily Record’, which also has the button to manually trigger pulling data from intervals.
