FAQ
Should principal_id be a user id?
Use the most stable billing-owner identifier you already have.
- If billing is per-user, a stable user id is fine.
- If billing is shared by an org, team, or workspace, use that stable org/team/workspace id.
- If ownership can change later, avoid using a transient login or context id directly. Choose a stable internal billing-owner id instead.
Can I retry a timed out write?
Yes. Retry with the same Idempotency-Key and the same body.
How do I obtain billing_account_id?
Use POST /mgt/v1/token/issue from your backend and store the mapping.
