To create a payload, a txjson XRPL transaction can be provided. Alternatively, a transaction formatted as HEX blob (string) can be provided in a txblob property.

Example contents of a payload

{% hint style="info" %} Take a look at the API Docs for more information about payloads object contents and possible replacement variables for the Return URLs. {% endhint %}

{
  txjson: {
    TransactionType: "Payment",
    Destination: "r...",
    Amount: "1000000"
  },
  options: {
    return_url: {
      app: "https://sample.test/?...",
      web: "https://sample.test/?id={id}"
    },
    force_network: "MAINNET"
  },
  custom_meta: {
    identifier: "123123",
    instruction: "Please sign this to..."
  }
}

The response of a Sdk.payload.create() operation, looks like this:

{
  "uuid": "1289e9ae-7d5d-4d5f-b89c-18633112ce09",
  "next": {
    "always": "https://xumm.app/sign/1289e9ae-7d5d-4d5f-b89c-18633112ce09",
    "no_push_msg_received": "https://xumm.app/sign/1289e9ae-7d5d-4d5f-b89c-18633112ce09/qr"
  },
  "refs": {
    "qr_png": "https://xumm.app/sign/1289e9ae-7d5d-4d5f-b89c-18633112ce09_q.png",
    "qr_matrix": "https://xumm.app/sign/1289e9ae-7d5d-4d5f-b89c-18633112ce09_q.json",
    "qr_uri_quality_opts": ["m", "q", "h"],
    "websocket_status": "wss://xumm.app/sign/1289e9ae-7d5d-4d5f-b89c-18633112ce09"
  },
  "pushed": true
}

The next.always URL is the URL to send the end user to, to scan a QR code or automatically open the XUMM app (if on mobile). If a user_token has been provided as part of the payload data provided to Sdk.payload.create(), you can see if the payload has been pushed to the end user. A button "didn't receive a push notification" could then take the user to the next.no_push_msg_received URL. The

Alternatively user routing / instruction flows can be custom built using the QR information provided in the refs object, and a subscription for live status updates (opened, signed, etc.) using a WebSocket client can be setup by connecting to the refs.websocket_status URL. Please note: this SDK already offers subscriptions. There's no need to setup your own WebSocket client: createandsubscribe.md
