Authorizations

Authorization
string
header
required

An API key minted at Settings › API & MCP. Send it as Authorization: Bearer <key>. A key carries its holder's own permissions, resolved on every call — revoking a membership closes the key's reach immediately. Keep it in an environment variable (GOOSY_API_KEY), never in a committed file.

Maximum string length: 128
