      🧾 Get Pending Invoices – Invoice Lookup#

      This method allows clients to retrieve pending invoices or outstanding balances for a specific postpaid product. It is the second step in the invoice payment workflow and must be executed using the dynamic fields obtained from the Get Parameters method.

      🔍 Description#

      Once the required fields are known (via Step 1), this endpoint is used to:
      Validate the customer’s account or reference
      Retrieve the list of pending invoices or total debt
      Obtain dynamic values such as transaction_code, which are required for payment
      The response also includes the payment type, which determines how the client can proceed (e.g., full payment only, partial invoice selection, or open wallet-style payment).

      📥 Request#

      The request body must be an array of key-value pairs, where each key corresponds to a field name returned in the query array from Step 1.

      Example Request#

      [
  { "key": "card_code", "value": "1234567890" },
  { "key": "installments_to_pay", "value": "2" }
]

      📤 Response#

      The response includes key information needed to prepare the payment request:
      additionalData: Dynamic fields required for the payment step (e.g., transaction_code)
      type: Payment behavior (TOTAL, DISCRETE, or OPEN)
      pendingInvoices: Number of invoices found
      amountToSendX100, destinationAmountX100, serviceFeeX100, totalAmountX100: Amounts in cents

      🧠 Usage Notes#

      This method must be called after retrieving the required fields via Get Parameters.
      The transaction_code included in additionalData is mandatory for the next step (Execute Payment).
      All monetary amounts are expressed in cents (e.g., 5000 = €50.00).
      The type field defines the payment strategy the client must respect during Step 3.
