Some of the API fields don't match the convention, this includes the list below but may contain others:

• `created` needs to be `created_at`
• `expires` needs to be `expires_at`
• `completed` needs to be `completed_at`

Also, expires_at is missing from the API spec:

Check that no other fields are using uncommon names from other services, update the field names, update the API spec, and make sure to let QA know the spec was changed.
