Hey all! 
@Michelle_Mabuyo here from the Apollo Education team. I’m a Developer Educator and I build courses for Odyssey, our official learning platform.
I’m back for the next edition of a multi-part series to teach you the basics of Apollo Connectors: a powerful way to bring existing REST APIs into your graph, all through configuration in the schema.
This week’s learning: Transforming data with methods in Connectors
REST APIs often return deeply nested or verbose data. Apollo Connectors let you reshape that data using transformation methods! To use the method, you’ll need to prefix it with an arrow (->). Here’s my top three most used, with examples for each!
first: Extracts the first item from an array.
To retrieve just the first variant of a product:
variant: variants->first {
price
quantity
}
entries: Converts an object’s key-value pairs into a list of objects.
To transform a collection of unique key-value pairs into objects with consistent keys:
specs: specs->entries {
name: key
value
}
size: Returns the length of a list.
To save the frontend client an extra step of calculating the number of elements in the array:
colorCount: colors->size

You can find a full list of methods in the Apollo documentation.

Have you used transformation methods in your Connectors? What methods do you want to see that aren’t implemented yet? Let us know!
