This can be done with the formula function MAP()! After you have retrieved the data from the REST API using Get Records, you can add the logic node Set Page Variable after it. Then, using a formula for the assigned value of the page variable, you can use MAP() to modify the original data to the same schema as the page variable, it would looks something like this:
So here you take the original data list, and for each item in the list you transform it to the same schema and property names as the page variable and assign the correct data from the original list to each property. The data.SoccerDataAppVar.___ depends totally on how these different properties are named in the original data list, the examples I used in my formula are just guesses from my part.
Note that the property names have to match exactly in your MAP() formula and in the page variable, and the data types need to match too.
