  title: SumUp REST API
  version: 1.0.0
  description: |-
    SumUp’s REST API operates with [JSON](https://www.json.org/json-en.html) HTTP requests and responses. The request bodies are sent through resource-oriented URLs and use the standard [HTTP response codes](https://developer.mozilla.org/docs/Web/HTTP/Status).

    You 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).

  - name: Checkouts
    description: |-
      Checkouts represent online payment sessions that you create before attempting to charge a payer. A checkout captures the payment intent, such as the amount, currency, merchant, and optional customer or redirect settings, and then moves through its lifecycle as you process it.

      Use this tag to:
      - create a checkout before collecting or confirming payment details
      - process the checkout with a card, saved card, wallet, or supported alternative payment method
      - retrieve or list checkouts to inspect their current state and associated payment attempts
      - deactivate a checkout that should no longer be used

      Typical workflow:
      - create a checkout with the order amount, currency, and merchant information
      - process the checkout through SumUp client tools such as the [Payment Widget and Swift Checkout SDK](https://developer.sumup.com/online-payments/checkouts)
      - retrieve the checkout or use the Transactions endpoints to inspect the resulting payment record

      Checkouts are used to initiate and orchestrate online payments. Transactions remain the authoritative record of the resulting payment outcome.

    description: |-
      Allow your regular customers to save their information with the Customers model.

      This will prevent re-entering payment instrument information for recurring payments on your platform.

      Depending on the needs you can allow, creating, listing or deactivating payment instruments & creating, retrieving and updating customers.
    x-core-objects:
      - $ref: '#/components/schemas/Customer'
  - name: Transactions
    description: |-
      Transactions represent completed or attempted payment operations processed for a merchant account. A transaction contains the core payment result, such as the amount, currency, payment method, creation time, and current high-level status.

      In 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:
      - `PAYOUT`: the payment being prepared for payout or included in a payout to the merchant
      - `REFUND`: money returned to the payer
      - `CHARGE_BACK`: money reversed after the original payment
      - `PAYOUT_DEDUCTION`: an amount deducted from a payout to cover a refund or chargeback

      From an integrator's perspective, transactions are the authoritative record of payment outcomes. Use this tag to:
      - list transactions for reporting, reconciliation, and customer support workflows
      - retrieve a single transaction when you need the latest payment details
      - inspect `simple_status` for the current merchant-facing outcome of the payment
      - inspect `events` or `transaction_events` when you need refund, payout, or chargeback history

      Typical workflow:
      - create and process payments through the Checkouts endpoints
      - use the Transactions endpoints to read the resulting payment records
      - use the returned statuses and events to update your own order, accounting, or support systems

      The Payouts model will allow you to track funds you’ve received from SumUp.

        Creates a payment checkout for the specified merchant, amount, and currency. Supply a `checkout_reference` to identify the payment attempt in your own systems. Creating a checkout does not charge a payment instrument.

        Set `hosted_checkout.enabled` to `true` to receive a [Hosted Checkout](https://developer.sumup.com/online-payments/checkouts/hosted-checkout/) URL where the customer can complete the payment.
        Use `redirect_url` for redirect-based payment and 3DS flows. If `return_url` is provided, SumUp sends processing updates to that backend callback URL.

        Complete the payment through [Hosted Checkout](https://developer.sumup.com/online-payments/checkouts/hosted-checkout/) or the [Payment Widget](https://developer.sumup.com/online-payments/checkouts/card-widget).

        Adds a member to the merchant account with the specified roles.

        By default, sends an invitation email to the provided address. The recipient must accept the invitation to join the account.
        When `is_managed_user` is `true`, creates a managed user with the provided password and optional nickname and assigns the roles directly, without sending an invitation.

        Creates a Checkout for a Reader.

        This process is asynchronous and the actual transaction may take some time to be started on the device.


        There are some caveats when using this endpoint:
        * The target device must be online, otherwise checkout won't be accepted
        * After the checkout is accepted, the system has 60 seconds to start the payment on the target device. During this time, any other checkout for the same device will be rejected.


        **Note**: If the target device is a Solo, it must be in version 3.3.24.3 or higher.

      description: |
        Terminate a Reader Checkout stops the current transaction on the target device.

        This process is asynchronous and the actual termination may take some time to be performed on the device.


        There are some caveats when using this endpoint:
        * The target device must be online, otherwise terminate won't be accepted
        * The action will succeed only if the device is waiting for cardholder action: e.g: waiting for card, waiting for PIN, etc.
        * There is no confirmation of the termination.

        If a transaction is successfully terminated and `return_url` was provided on Checkout, the transaction status will be sent as `failed` to the provided URL.


        **Note**: If the target device is a Solo, it must be in version 3.3.28.0 or higher.
