Provision an organization (service key)
Create a Zelto organization headlessly from an automation (e.g. a Slack/CRM provisioner) during a sales call. Finds-or-creates the owner user by email, creates the org and an owner member, seeds signup credits, mirrors to the analytical store, and emails the owner an invite to set up their login.
Requires an admin/service API key — read-only org-scoped customer keys are rejected with 403. Idempotent: a repeat call with the same owner email and org name returns the existing org (created.org=false) instead of duplicating.
Authorizations
Send Authorization: Bearer YOUR_API_KEY. The key resolves to a single organization.
