Build with Magnum

Magnum combines Pix checkout, an integration API and payment tracking for a business that wants to follow receipt and settlement in one place.

Product surfaces

The website, account flows, merchant dashboard and developer documentation are available in Portuguese and English. The browser checkout can run inside an authorized website, while the API retains authority over the amount, network, destination and payment state.

• One business per account: integrations and records belong to that business.
• Checkout: responsive appearance, locale settings and short-lived sessions.
• API: scoped server keys, exact monetary values and idempotent requests.
• Events: persisted history and signed webhook deliveries.
• Operations: separate web, API, worker and PostgreSQL services.

Availability

The available payment environment is sandbox, which moves no money and returns non-payable demonstration codes. Live payments remain disabled pending explicit approval of the provider arrangement and account capabilities.

The business may configure fixed network/asset receiving addresses in Settings. That configuration does not activate payments, and the payer cannot choose an arbitrary wallet. The operator alone manages the backend 4P credential; a shared credential must never be interpreted as provider authorization for a multi-business commercial model.
