# `Gamend.OAuth.Exchanger`
[🔗](https://github.com/appsinacup/gamend/blob/v1.0.7/lib/gamend/oauth/exchanger.ex#L1)

Default implementation for exchanging OAuth codes with providers.

This module is intentionally small and works with the Req library.
Tests may replace the exchanger via application config for easier stubbing.
