It uses resource-oriented URLs and standard [HTTP response codes](https://developer.mozilla.org/docs/Web/HTTP/Status). Send request bodies as [JSON](https://www.json.org/json-en.html) with `Content-Type: application/json`, unless an endpoint specifies another format.\n\nYou can experiment and work on your integration in a sandbox that doesn't affect your regular data and doesn't process real transactions. To create a sandbox merchant account visit the [dashboard](https://me.sumup.com/settings/developer). To use the sandbox when interacting with SumUp APIs [create an API](https://me.sumup.com/settings/api-keys) key and use it for [authentication](https://developer.sumup.com/api/authentication).",

A transaction contains the core payment result, such as the amount, currency, payment method, creation time, and current high-level status.\n\nIn addition to the main payment outcome, a transaction can contain related events that describe what happened after the original payment attempt. These events provide visibility into the financial lifecycle of the transaction, for example:\n- `PAYOUT`: the payment being prepared for payout or included in a payout to the merchant\n- `REFUND`: money returned to the payer\n- `CHARGE_BACK`: money reversed after the original payment\n- `PAYOUT_DEDUCTION`: an amount deducted from a payout to cover a refund or chargeback\n\nFrom an integrator's perspective, transactions are the authoritative record of payment outcomes. Use this tag to:\n- list transactions for reporting, reconciliation, and customer support workflows\n- retrieve a single transaction when you need the latest payment details\n- inspect `simple_status` for the current merchant-facing outcome of the payment\n- inspect `events` or `transaction_events` when you need refund, payout, or chargeback history\n\nTypical workflow:\n- create and process payments through the Checkouts endpoints\n- use the Transactions endpoints to read the resulting payment records\n- use the returned statuses and events to update your own order, accounting, or support systems"
