createAndSubscribe( … )

The <PayloadAndSubscription> object is basically a <PayloadSubscription> object with the created payload results in the created property:
All information that applies on Sdk.payload.create() and Sdk.payload.subscribe() applies. create( … ) / subscribe( … ) Differences are:
  1. 1.
    The input for a Sdk.payload.createAndSubscribe() call isn't a payload UUID / existing payload, but a payload to create.
  2. 2.
    The response object also contains (<PayloadAndSubscription>.created) the response obtained when creating the payload.

Example code

xumm.payload.createAndSubscribe({
TransactionType: 'Payment',
Destination: 'rfHn6cB5mmqZ6fHZ4fdemCDSxqLTijgMwo',
Amount: String(1000000) // one million drops, 1 XRP
}, eventMessage => {
if (Object.keys(eventMessage.data).indexOf('opened') > -1) {
// Update the UI? The payload was opened.
}
if (Object.keys(eventMessage.data).indexOf('signed') > -1) {
// The `signed` property is present, true (signed) / false (rejected)
return eventMessage
}
})
.then(({ created, resolved }) => {
console.log('Payload URL:', created.next.always)
console.log('Payload QR:', created.refs.qr_png)
return resolved // Return payload promise for the next `then`
})
.then(payload => console.log('Payload resolved', payload))
// This is where you can do `xumm.payload.get(...)` to fetch details
