Get Organizations

Lists every organization accessible to the calling partner, with the partner's owner organization first. In `2025-09-18`, this endpoint is partner-scoped rather than a general "current caller visibility" listing. The partner owner organization is returned first, followed by child organizations. This ordering matters for partner workflows such as shared connections, where the parent connection must live in the partner owner organization. If you need only the organization implied by the current credential, use [`GET /api/organization`](../../api-reference/organization/get-current) instead.
