getTransaction( … )

Fetch an XRPL transaction & metadata. Please don't use this method unless absolutely necessary: please set up your own connection to an XRPL node to fetch this information.
The getTransaction method allows you to get the transaction outcome (mainnet) live from the XRP ledger, as fetched for you by the XUMM backend.
Note: it's best to retrieve these results yourself instead of relying on the XUMM platform to get live XRPL transaction information! You can use the xrpl-txdata package to do this:
npm version
const txInfo = await Sdk.getTransaction(txHash);
Returns: <XrplTransaction>
