# Get Billing Postpaid

`GET /api/app-auto-gtm/billing/postpaid`

AutoGTM postpaid (overdraft) tier state for the Billing UI.

Returns the active slot's headroom + settled count + the org's
current tier rung. The tier_number / tier_cap_credits fields are
populated even when no active slot exists so prepaid users
(no card / no overdraft history) still see a meaningful "Tier 1
up to $5" subtitle on the unified balance card (issue #801).
