# Buy a credit pack with MPP

`POST /api/v1/credits/packs/mpp`

## Request

- Base URL: `https://spoolis.com`
- URL: `https://spoolis.com/api/v1/credits/packs/mpp`
- Auth: HTTP bearer

Issues an MPP card challenge or accepts a verified MPP credential. The payment webhook credits the ledger after the provider confirms payment. Full-scope and verify-scoped account keys are accepted. On the paid retry, send the Spoolis key in the X-Api-Key header and the MPP credential as the Authorization Payment scheme; wallet clients own the Authorization header, so keep the Spoolis key out of it. Comma-separated Authorization schemes are also accepted.
