# Activate Subscription Endpoint

`POST /api/payment/activate-subscription`

Confirm card attached via SetupIntent — set default PM on Customer.

No Stripe Subscription is created. The card-trial bonus (5000 credits)
is granted asynchronously by the ``setup_intent.succeeded`` webhook
via ``api.app_auto_gtm.card_trial.ensure_user_and_grant``.

Endpoint name kept for frontend backwards-compat — historically this
DID create a Subscription before postpaid-v2 (see git history of this
file for context).
