If anyone has found an easier way of doing this i would be interested to hear from you.

I don't know what language you're using, but here's a snippet of Ruby I used for a toy app of mine. It results in an array of hashes each with an ID and a name; the full finalized data structure can be seen at http://achieveit.heroku.com/ach

def parse_achievements(ach)
final = []
ach.each do |value|
if value.has_key?("achievements") || value.has_key?("categories")
if value.has_key?("achievements")
final.push(parse_achievements(value["achievements"]))
end
if value.has_key?("categories")
final.push(parse_achievements(value["categories"]))
end
else
final.push({'id' => value["id"], 'name' => value["title"]})
end
end
final.flatten
end

The full source for the main file is at https://gist.github.com/2432197.

Please note I made this app in a couple hours and haven't looked at, according to the Git log, since November--so I make no guarantees that it still works at all. :)

Cyaga, does that do any way of pairing up with who got the achievement?

No, it doesn't--it's simply a flattened view of the data at http://us.battle.net/api/wow/data/character/achievements (while only keeping the ID and achievement name around).

At https://gist.github.com/2433774 you can find another script I threw together to build a giant flattened hash of all the achievements, keyed by their IDs; it also keeps track of which category/subcategory the achievement is in. There is some example output in case you don't have Ruby on your machine.

Once the data is flattened like this, it's easy to look up an achievement by its ID or search through the array for other criteria.

As for matching up earned achievements, I think you're on the right track. The JSON response for a character with achievements included returns six arrays: achievementsCompleted, achievementsCompletedTimestamp, criteria, criteriaQuantity, criteriaTimestamp, and criteriaCreated. The first two arrays have the same length, as do the last four.

If, say, you wanted to see the character's most recent achievement, you could find the largest timestamp in the achievementsCompletedTimestamp array and store its position in that array. Find the element in the same index in the achievementsCompleted array, and that is the ID of the achievement that was completed. Finally, use that ID to find the achievement data (which is where the flattened view of achievement data is useful) and you have what you're looking for.
