API keys
InkLink uses organization API keys, all in the form secret_live_xxx.
Using the key
From your backend, send the full key string on every request as the api-key HTTP header:
Never expose API keys in browsers, client-side JavaScript, or mobile app bundles. InkLink requests must run only on your backend–route end-user traffic through your server so the key never ships to clients.
Where to create keys
Create API keys in the InkLink dashboard on platform.inklink.com; in the sidebar, open Manage → API Key, then use New API Key.
