question

My main objective is to apply a payment with a pre-existing tender.

My understanding is that this needs to be set either through the tenderConnector or provided in the resulting intent? How can the tender to perform the payment with be defined in the result intent?

Intent resultIntent = new Intent();
resultIntent.putExtra(Intents.EXTRA_AMOUNT, amount);
resultIntent.putExtra(Intents.EXTRA_CLIENT_ID, userId);

// TODO select the specific tender 

resultIntent.putExtra(Intents.EXTRA_NOTE, "Example note");

setResult(RESULT_OK, resultIntent);

finish();
