Missing Achievement IDs

API Discussion

I’m unable to find the ID for a few achievements anywhere online:
Three’s company 2400
Three’s company 2700

Wowwiki has a list of achievement IDs - it’s quite comprehensive except for these achievements.

Are the IDs for these achievements available anywhere?
