# createTokenPurchase

mutation · in the family [Token purchase](/reference/token-purchase/)

## What it does

Buy kernels — top up your group’s prepaid balance.

Buy platform tokens for the caller's group: resolves the group's wallet via the singleton marker (no wallet → NOT_FOUND/CONSTRUCT: open the TokenAccount first; a PAUSED wallet refuses CONFLICT/REF_STATE), gates real money by classification × Stripe mode (ruling — live-mode requires a production group; test-mode legal always), resolves the volume tier + computes tokensPurchased SERVER-side, mints the platform TEST PaymentIntent with the ruling- join metadata BEFORE the record (PI-first — a processor refusal aborts with NOTHING written; an orphaned TEST intent is the deferral-14a reconcile class), then commits the record carrying the pi_… ref. Settlement is the WEBHOOK's (ruling — the existing 8-event roster; succeeded posts the purchase entry + balance atomically; failed/canceled settles failed). Requires the unrestricted capability. Template class A16_BILLING (hand-derived v23).

## What happens

Charges your billing method and credits the balance in one recorded purchase.

## Careful

Real money for platform credits.

## Returns

[TokenPurchase](/types/TokenPurchase/) `TokenPurchase!` — A TokenPurchase — buying platform tokens with real money (\*\*Stripe primary\*\*; ACH/wire/invoiced = deferral 7): $ → tokens at the volume tier (tier_1 | tier_2 | tier_3 — SERVER-computed, never client-asserted), loaded into the GROUP's TokenAccount as a purchase TokenEntry when the webhook settles. \*\*AT/stack charging the MERCHANT\*\* — the platform account's OWN PaymentIntent (distinct from the merchant's customer Payments and the Connect plane). \*\*NON-REFUNDABLE\*\*. The FSM is the ratified 3-STATE table VERBATIM: created(i) → succeeded ▣ / failed ✦, BOTH edges system:stripe_webhook — NO caller transitions and NOTHING mutable between birth and settlement ⇒ the wire realizes {create:true, update:false, transitions:false} (a NEW suppression combination — the webhook-settled document). The birth op mints the TEST PaymentIntent api-side with the LOAD-BEARING metadata {at_kind, tokenPurchaseId, rootId} (ruling — the lesson: PI metadata IS the join key; the EXISTING platform 8-event endpoint roster covers the lane — payment_intent.succeeded/payment_failed/canceled; canceled settles failed). The real-money gate = classification × Stripe MODE (ruling: live-mode charges require a production-classified group; test-mode is legal for ANY classification — that is how the goldens run; the mode derives from the custodied key, never asserted). Purchase-abandon reconciliation beyond canceled = deferral 14a. NOT searchable. Template class A16_BILLING (hand-derived v23).
