Authentication

API Keys

Overflow authenticates requests with header-based API keys. Contact Overflow developers to manage your API credentials.

Header	Example	Purpose
`x-client-id`	`c77c8d57-7e1c-4a7e-ad46-e756e5f8dabd`	Public identifier
`x-api-key`	`31d1467ffa4262cf71b1a600f2d8a425`	Secret key

The credentials are intended to be used server-side and shouldn’t be exposed in client-side code, public repos, or logs.
