# What does this PR do? Adds a `/alpha/` prefix to all the REST API urls. Also makes them all use hyphens instead of underscores as is more standard practice. (This is based on feedback from our partners.) ## Test Plan The Stack itself does not need updating. However, client SDKs and documentation will need to be updated.
