A sign request in Xumm is a prompt to approve a transaction or action on the XRP Ledger. This page will show you how you can create a Sign Request, and how you can deliver the request to the end user.
When creating Sign Requests from a backend environment, the Xumm SDK is called with your API Key & Secret. A payload can be opened by any user. A user will not get notified about a payload, unless if they interacted with the payload through a deeplink or scanning the Payload QR code.
If you want to deliver backend created Sign Requests to a user & the user is identified by your application, you have to provide a user_token to the payload. The user_token can be obtained after the user interacted with your application & signed a payload. See: Push​
import { Xumm } from "xumm"
const xumm = new Xumm("some-api-key", "some-secret-key")
const payload = await xumm.payload?.create({
user_token: 'xxxx',
txjson: {
TransactionType: 'SignIn'
To decide where the user is sent after signing the payload, please read: Payload Return URL​
