API reference
Every endpoint in the Volume API, with a playground you can send requests from.
One base URL, https://api.paywithvolume.com, and the API key decides the mode:
vk_test_ or vk_live_. See API keys and modes.
Each page carries a playground. It sends through this site rather than straight from your browser, so a test key works without any CORS setup of your own. It takes test keys only: keep a live key on your server.
