# Blocks can be executed before or after every API call, using `before`, `after`,
# `before_validation` and `after_validation`.
#
# Before and after callbacks execute in the following order:
#
# 1. `before`
# 2. `before_validation`
# 3. _validations_
# 4. `after_validation`
# 5. _the API call_
# 6. `after`
#
# Steps 4, 5 and 6 only happen if validation succeeds.
