The invoice being processed for this transaction @readonly

The type of transaction being attempted (defaults to Sale if the invoice is not already paid, Refund if it is already paid)

Given the current state of the invoice and transaction, is a signature required to secure payment? @readonly

Digital Card information

id of the PP order for payment

While building your invoice, the running total will be displayed on PaymentDevices capable of displaying messages. If you set totalDisplayFooter, that will be displayed (centered) after the total amount. Note that once the payment flow starts, EMV certification requires that the display just show the total and iconography corresponding to expected payment types. Your message will not be on that screen.

Returns the current state of payment

Returns the current state of tipping

Clear the on-reader tip that was acquired for this transaction

Begin the payment flow (activate payment devices, listen for relevant events from devices)

Begin the flow to issue a refund on the current invoice.

Begin the flow to issue a refund on the current invoice.

Is the transaction a type of refund?

Deactivate form factors without ending the transaction. Once deactivated, you should re-begin the transaction to start taking payments

Abort an idle transaction abandoning activated readers and all event listeners. The completed event will NOT be fired for this TransactionContext given that you have explicitly abandoned it

Check to see if payment is in ‘retry’ state. This check helps with disconnection/connection logic when the app goes in the background.

Request to cancel a payment. The request will only be accepted if payment is not already in progress.

Request to cancel an ongoing payment. The request will only be accepted if there is a partial digital card payment and payment is not in progress.

Remove all handlers

Discard the presented card for non-EMV transactions only

Begin the flow to issue a refund on the current invoice.

Continue processing transaction with Digital Card/Code information

Continue processing a transaction - the behavior of which depends on the presented card. If it’s a magnetic card or an NFC tap, payment will be attempted and money will move (if successful). If it’s an EMV card insertion, we will start the EMV flow which includes a few calls to the server, potentially asking the user to enter a PIN, etc.

Sync the Invoice total to the reader display. Use this function to sync invoice amount on the app to the reader. This automatic invoice syncing will stop based on the transaction state. Use ‘syncInvoiceOnce’ to do an on-demand push invoice total to the card reader display

Do a one time sync of invoice total to card reader

Continue processing a cash transaction.

Continue processing a QRC transaction.

Continue processing a check transaction.

If you acquire signatures yourself, for example from a Topaz Pen Pad or with an external camera, set this property to a handler that will be invoked when signature should be collected. Once you’ve collected the signature, call the supplied signatureReceiver with a base64 encoded JPG of the signature. Try to keep it under 100k.

Provide a token expiration handler if you want to handle token expirations during a transaction

Provide a handler to get notified after chip card insert is detected but before EMV data is read. cardInsertedHandler.continueWithCardDataRead must be invoked to continue with transaction

Provide a handler to get notified when card was presented and emv/magstripe data was read. TransactionContext.continueWithCard should be invoked to continue the payment

Provide a handler to get notifications for QRC Payment

Provide a handler to get notified once transaction is complete

Provide a handler to get notified once vault is complete

Provide a handler to get offline transaction addition notification

If you would like to display additional receipt options such as print, etc., you can provide them here. These options would be presented on the receipt screen below the Email and Text options.
