Authentication

Learn how to authenticate your requests to the WinWinKit API.

Every request to the WinWinKit API must include an x-api-key header with your API Key.

curl -X GET "https://api.winwinkit.com/users/your-app-user-id" \
  -H "x-api-key: your-api-key"

The same header shape applies to every endpoint:

{
  "headers": {
    "x-api-key": "<your-api-key>"
  }
}

If the key is missing, invalid, or revoked, the API returns 401 UNAUTHORIZED — see Errors for the full error contract.
