# PaymentParameters

class PaymentParameters

Parameters to describe a single payment made using Mobile Payments SDK. Use Builder to create and configure payment parameters, for example:

    val paymentParameters = PaymentParameters.Builder(Money(350, USD), AUTO_DETECT)
       .paymentAttemptId("SK95TM0")
       .autocomplete(true)
       .orderId("YZ2319D")
       .tipMoney(Money(100, USD))
       .referenceId("1314387")
       .build()

## Types

Builder
Link copied to clipboard
class Builder(amount: Money, processingMode: ProcessingMode)

The builder used to create PaymentParameters. An amount of money and processingMode are required to build a PaymentParameters. In addition, Builder.paymentAttemptId or (deprecated) Builder.idempotencyKey must be set.

## Properties

acceptPartialAuthorization
Link copied to clipboard
val acceptPartialAuthorization: Boolean

Allows successful authorization of a part of the requested amountMoney. Defaults to false. It is necessary to check the returned Payment object to determine the actual amount authorized.

amountMoney
Link copied to clipboard
val amountMoney: Money

The amount of money to accept for this payment, not including tipMoney, but including any appFeeMoney.

appFeeMoney
Link copied to clipboard
val appFeeMoney: Money?

appFeeMoney is an amount of money paid to a marketplace or application developer instead of the selling merchant, as a fee for processing the payment. Square takes the specified portion of the amount from the payment and deposits it in the developer account balance. For payments (including tip) greater than or equal to

$5.00, the maximum application fee percentage is 90%. For amounts below $

5 the maximum application fee percentage is 60%.
autocomplete

val autocomplete: Boolean

Most transactions immediately "capture," but this setting can delay that. It is `true` by default, but if set `false`, then the card will be processed up to authentication, and will complete or cancel based on the delayDuration and delayAction settings.

customerId

val customerId: String?

Optionally set to the customer Id of the purchaser.

delayAction
Link copied to clipboard
val delayAction: DelayAction?

Action to take after delayDuration has expired without payment the authorized payment being either completion or cancellation. By default, this will be CANCEL unless explicitly set.

delayDuration
Link copied to clipboard
val delayDuration: Long?

Delay between creating a payment with autocomplete=false and when Square will automatically cancel the payment. Expressed in milliseconds here, because that is the JVM standard, but sent truncated to minutes (60,000ms), because a 5 millisecond delay is silly. Unused when autocomplete=true, because the payment will be completed or failed immediately.

locationId
Link copied to clipboard
val locationId: String?

Optionally override the location provided when authenticating to Mobile Payments SDK.

note
Link copied to clipboard
val note: String?

An optional note to annotate a payment.

orderId
Link copied to clipboard
val orderId: String?

The order associated with this purchase, or `null` if there is no order. Orders can be manipulated with the Orders API, and associate a transaction with the specific line items purchased in that transaction.

paymentAttemptId
Link copied to clipboard
val paymentAttemptId: String?

A unique identifier for the payment attempted with PaymentManager.startPaymentActivity. When provided, Mobile Payments SDK generates a unique idempotency key for the payment request and stores it with the payment attempt ID. If multiple payment requests are made for the same payment attempt (e.g. due to Strong Customer Authentication (SCA) requirements in Europe), the SDK generates a new idempotency key for each request and replaces the stored idempotency key for the payment attempt ID.

processingMode
Link copied to clipboard
val processingMode: ProcessingMode

The processingMode parameter determines whether the current payment needs to be processed online or offline. By default, this will be AUTO_DETECT unless explicitly set.

referenceId
Link copied to clipboard
val referenceId: String?

Optional value that can be used to associate a reference to some external system with this payment. The value is not used by Square. The same value is returned in a successful Payment response.

statementDescription
Link copied to clipboard
val statementDescription: String?

An override of the description line on the buyer's statement. Will be prefixed with Square's "SQ*" prefix, and may be truncated by the bank during generation.

teamMemberId
Link copied to clipboard
val teamMemberId: String?

Optional team member to associate with the payment.

tipMoney
Link copied to clipboard
val tipMoney: Money?

The amount charged as a tip, in addition to amountMoney.
