Signed & Delegated Requests

Signed & Delegated Requests are slightly more complex than the methods described in Basic Usage. Before making a Signed & Delegated API request; you need to obtain a ConsumerKey and SharedSecret for the user you are making requests on behalf.

This can be done using 3-Legged-Authentication which is described in detail here

Assuming you have successfully acquired a ConsumerKey and SharedSecret for the user; then you can retrieve data which is specific to that user.

For example; for our user (Steve French) we can retrieve the nutritional information of all food diary entries for a specified day.

> fatsecretR(fatsecret, "getFoodEntry", "2016-12-20", SteveFrenchToken, SteveFrenchSecret)

NOTE: dates must always be in the format YYYY-MM-DD
