Authentication

Every External Cloud API request requires API credentials and a whitelisted caller IP.

Headers

Header	Description
`client-id`	Public client identifier from Developer Tools
`client-secret`	Secret key — never ship it in browser code

IP whitelist required Requests from IPs not listed under Developer Tools → IP Whitelist are rejected. Use GET /external-api/ping to discover the IP Washeej sees.
